Most ABM agencies don't fail their clients because of poor creative or poor execution. They tend to fail because of two key areas: Firstly, they fail to challenge the client on whether they are truly ABM ready and, secondly, they don't work backwards from revenue. ABM agencies are after all meant to be revenue accelerators. In 2026, with Account-based Marketing now adopted by so many  B2B organisations, the gap between what great ABM agencies deliver and what average ones do has never been wider. Understanding that gap -  before you engage an ABM agency such as strategicabm - is the difference between transforming your pipeline and wasting precious time, budget, and opportunity.

A great ABM agency in 2026 is defined by its ability to deliver:

  • Strategic depth - treating ABM as a company-wide go-to-market discipline, not a campaign or a technology deployment
  • Revenue-tied measurement  - attributing pipeline, deal velocity, and closed revenue to specific account-level activities, not impressions or MQLs
  • Sales and marketing alignment - structurally bridging the gap between sales and marketing through shared account intelligence, joint planning, and integrated execution
  • Outcome-driven playbooks - matching the right ABM model and engagement framework to each account's stage, buying group complexity, and relationship maturity
  • Speed to value - compressing the "figuring it out" phase through proven frameworks, repeatable playbooks, and experienced practitioners
  • Scale architecture - building the foundations, training, and internal capability that allow ABM to grow beyond a pilot without fragmenting
  • Human-first AI integration - applying AI to accelerate insight, personalization, and execution without losing the strategic judgment that makes ABM work
ABM Lunch and Learn

An ABM Agency is meant to challenge you

 In practice, this means:

  • Great ABM agencies ask uncomfortable questions before they make recommendations - about readiness, alignment, and what success actually means to the business.

  • They build value propositions from account intelligence, not assumptions - and those VPs become the North Star for all messaging and content.

  • They engage buying groups, not contacts - understanding the dynamics, politics, and priorities of every stakeholder who influences a decision.

  • They measure what matters to CEOs and CFOs - revenue, retention, deal size, lifetime value - not what's easy to track in a campaign dashboard

  • They build internal mastery, not external dependency - the goal of a great agency relationship is to make itself progressively less necessary

  • They treat ABM failure as an organizational problem to diagnose, not a campaign problem to optimise

The single biggest distinction

There is one word that separates great ABM agencies from average ones: clarity.

Not the false certainty of "run these plays, hit these accounts, generate this pipeline."

That's demand gen with a badge.

And it's what a significant proportion of the market is selling under the ABM label.

Real clarity comes from an agency that has already made the mistakes your team hasn't made yet. That has worked across enough markets, industries, buying groups, and deal motions to know where the friction lives before you find it yourself.

That can replace months of internal debate and trial-and-error with structure, momentum, and a clear path to value.

The best ABM agency relationships don't start with a brief. They start with a conversation where the agency understands your problem before you've fully articulated it yourself.

"They wanted certainty. We offered clarity. Those aren't the same thing. And no proposal in the world closes that gap."

That distinction - between certainty and clarity - is the lens through which every agency evaluation should begin.

What clients actually want from ABM Agencies

The evidence on what clients want from ABM agencies is remarkably consistent - whether it comes from Forrester, Momentum ITSMA's benchmark studies, or direct client research conducted in the field.

When asked what they want from ABM, clients identify four things above all elseQuantifiable outcomes

1. Deliver ROI. Justify budget.

Connect the dots to business outcomes that the CEO and board care about. Not impressions. Not MQLs.

Revenue, pipeline, win rates, and deal size. Boards don't buy theory - they buy outcomes. CEOs don't ask "is ABM a good marketing strategy?" They ask "does this drive revenue, retention, and long-term value?" The agency that answers that question in business terms - not marketing terms - earns the room.

2. Speed

Speed to deep insights. Speed to meaningful personalization. Speed to market. Speed to time-to-value.

In 2026, speed isn't a luxury - it's a requirement. The agency that compresses the "figuring it out" phase into weeks rather than quarters is the one that earns the relationship and justifies the budget. 

Look for an ABM Agency that acts as an "accelerator". 

3. Scale

Foundations for scale. Meaningful personalization at scale.

The ability to extend ABM to new regions, new industries, and new tiers of accounts without rebuilding from scratch. Most ABM pilots work. The agencies that differentiate themselves are the ones that know how to build for what comes after the pilot.

4. Agility and simplification

On-demand support for sales. Models that build internal capability rather than external dependency. Simplified programs that don't require a PhD to run.

The ability to adapt as priorities shift, budgets change, and the go-to-market motion evolves.

Momentum ITSMA's 6th Annual ABM Benchmark Study (surveying 279 practitioners) quantifies the outcome priority:

  • 90% want active engagement** with target accounts

  • 84% want pipeline growth

  • 77% want revenue growth

These are outcomes, not activities - a distinction that defines how sophisticated buyers evaluate agencies.

Forrester's data puts numbers on what great looks like: ABM practitioners most commonly report:

  • 21–50% higher ROI versus non-ABM marketing.

  • Companies embracing buying-group strategies have seen a 17× increase in conversion rates

  • And a 4× improvement in win rates.

ABM Heroes (Terry Osborne)

The ten reasons buyers hire ABM agencies

Behind closed doors, the real reasons clients engage ABM agencies are more instructive than any RFP document. Here is what consistently emerges:

1. Hard-won experience you can't shortcut

You're not buying people. You're buying battle scars. Agencies bring lived experience across markets, industries, personas, and deal motions - without you paying the tuition fee yourself. The value isn't in their capability - it's in having already learned where things go wrong.

2. They eliminate the "figuring it out" phase

Most ABM failure happens before the first campaign launches - in the months spent debating strategy, alignment, account selection, and measurement. Great agencies replace that uncertainty with structure and momentum from day one.

3. They act as growth accelerators

ABM agencies compress time. That's the real ROI. Instead of months of internal debate and trial-and-error, you test faster, learn faster, and scale sooner. In 2026, speed isn't a competitive advantage. It's a baseline requirement.

4. They provide capabilities you'll never fully build in-house

ABM demands too many specialists to own internally - value proposition experts, messaging strategists, creatives, technologists, data specialists, and activation consultants. Agencies provide instant access to the full range without the hiring cycles, management overhead, or attrition risk.

5. They solve problems you don't know you have yet

ABM rarely fails on tactics. It fails on friction - misaligned incentives, unclear ownership, sales teams that don't engage, measurement frameworks that measure the wrong things. A neutral, external voice often surfaces and solves these structural problems faster than internal teams can.

6. They align teams around outcomes, not activities

No one comes to an ABM agency asking for campaigns. They come asking for market entry, enterprise account growth, competitive displacement, and pipeline acceleration. Strong agencies reverse-engineer execution from outcomes - and keep everyone accountable to the revenue metrics, not the activity metrics.

7. They reduce risk, not just cost

Building ABM capability internally looks cheaper until it fails - and by the time it fails, you've spent the budget and lost the year. The real comparison isn't agency versus salary. It's certainty versus experimentation.

8. They bring frameworks, not opinions

Systemized ABM wins. Proven frameworks. Repeatable playbooks. Clear operating models. The difference between an agency that has run ABM for one company and one that has run it for hundreds is the difference between a belief and a system.

9. They lead AI adoption without letting AI lead

The best agencies know where AI compounds value in ABM - and where it creates the illusion of progress while eroding quality. Human-first. AI-accelerated. Strategy-led. That's the model that works. Not prompt tricks and generic outputs, but AI applied precisely at the stages of the ABM journey where it genuinely accelerates results.

10. They build internal mastery, not external dependency

Great ABM agencies don't just deliver. They upskill. The goal isn't to outsource ABM forever - it's to create elite internal ABM practitioners who can eventually scale the model without ongoing agency support.

The ABM readiness reality most agencies won't tell you

Here is an uncomfortable truth that separates honest ABM partners from those simply chasing engagement:

Most companies aren't ready for ABM when they think they are. 

The teams that succeed aren't the ones with the best tech stacks or the biggest budgets. They're the ones honest enough to admit what isn't working before they start. The ones who invest in getting ready - not just in getting started.

A useful readiness diagnostic asks ten questions. Not about platforms or target account lists - but about whether the organisation is structurally capable of doing ABM:

1. Can Sales describe their top account's biggest challenge - and do they agree on who those accounts are?

2. Do Sales and Marketing agree on what a "good fit" account looks like?

3. Has your CEO spoken to a target account in the last 90 days?

4. Do you know why your last three lost deals actually said no - the real reason, not the CRM version?

5. Could you pause all paid media tomorrow and still generate pipeline?

6. If you asked Sales to score Marketing's contribution from 1–10, would you want to hear the answer?

7. Do you have the budget and the people to run ABM properly - not "we'll figure it out as we go"?

8. Can you measure ABM success against business objectives - not impressions or MQLs?

9. Have you defined what ABM means for your business - not what it means in the dictionary?

10. Is your current marketing strategy actually delivering? ABM is not a silver bullet for broken marketing.

Most teams score 3 out of 10.

Some score lower. That is not a failure - it's a starting point. The great ABM agencies use exactly this kind of diagnostic before proposing anything. Those that skip it are selling you a program you're not ready to run.

ABM case study

The questions that signal whether you're talking to a great ABM agency

There is a reliable tell for whether an ABM agency is genuinely sophisticated and truly able to help you "move the dial." 

It's not the credentials deck or the case study roster. It's the questions they ask -  and the questions they help you ask yourselves.

The best teams in the market have moved beyond "what tech stack?" and "what budget?" to the uncomfortable, structural questions that actually determine whether ABM will work:

  • What does ABM look like in a fragmented market - and when does segmentation break?

  • How do we turn experiments into a repeatable ABM programme? Tests don't scale. Systems do.

  • Which parts of ABM can we realistically outsource, and where are our real capability gaps?

  • How do we systemize Sales and Marketing collaboration? Alignment needs rituals, not slides.

  • How do we know if our ABM is working - and what does traction in the right accounts actually look like?

  • How do we scale without losing personalisation? Tiering, modular plays, meaningful relevance.

  • How do we make our CRM work for ABM - shifting from a contact database to an account intelligence engine?

  • How do we make ABM more than a marketing project - from silo to system, from tactic to transformation?

  • How do we benefit from AI without losing our north star? Human-first. AI-fast.

These aren't conference questions. They're leadership questions.

They're the difference between "doing ABM" and building a GTM engine around it.

The agency that surfaces these in the first conversation - before any proposal - is the one worth engaging.

The intimacy problem - why most ABM fails before it starts

Ask any marketer to describe their number one target account and you'll get one of two responses.

The data version:

They're a $2bn enterprise in financial services. They scored 85 for client satisfaction. We've got 3 contacts in the CRM.

 

The relationship version:

Their new CMO inherited a strategy she doesn't believe in - but can't say that publicly yet. They renewed with their current vendor reluctantly. The contract's up in September. That's our window.

The first is a Salesforce record.

The second is a relationship.

Marketing doesn't fail because of bad tech, wrong channels, or missing content. It fails because teams don't actually know the accounts they're targeting. It's an intimacy problem.

You can't personalise what you don't understand. You can't be relevant to someone you've never listened to. You can't build a relationship with a database entry.

Great ABM agencies know this.

Their research methodologies go beyond firmographics and intent signals to develop genuine account intelligence - understanding the pressures, politics, ambitions, and anxieties that drive decision-making within each target account.

This is the foundation on which effective personalisation is built. The ITSMA Three Rs framework captures the hierarchy:

  • Reputation

  • Relationships

  • Revenue

The agencies that deliver Revenue consistently are the ones that invest first in Reputation and Relationships - and build their entire methodology around that sequence.

Let's talk ABM

How great ABM agencies structure their approach

The most effective ABM agencies operate through a consistent methodology that moves from intelligence to execution across a clear journey. The best frameworks share five common phases:

  • Phase 1: Objective setting and ICP development

Discovery workshops with Sales and Marketing. Building and validating the Ideal Customer Profile at account, persona, stakeholder, and buying group level. ROI modelling. This phase is where most agencies rush - and where the best ones slow down. The quality of everything that follows depends on the quality of the intelligence gathered here.

  • Phase 2: Target account selection, tiering, and segmentation

Not all accounts are equal, and great agencies build the methodology to prove it. Accounts are tiered by deal complexity - from transactional single-buyer decisions to cross-functional multi-stakeholder deals to strategic enterprise partnerships requiring entirely different engagement models. Each tier demands a different depth of investment and personalization:

One-to-one ABM offers deep, bespoke engagement for the highest-value accounts

One-to-few ABM is a cluster-based personalization for accounts sharing common challenges

One-to-many is a programmatic engagement for broader market development

  • Phase 3: ABM Value Proposition development

This is what separates ABM from brand marketing. Where brand VPs speak to all potential buyers, ABM VPs are built from account intelligence, co-created with Sales, and relevant only to the specific accounts in the program.

They define the unique value the client offers to solve those accounts' specific challenges — and they become the North Star for all campaign messaging, content, and creative that follows.

  • Phase 4: Playbook selection and delivery

Outcome-driven playbooks matched to account stage and buying signal:

Awareness playbooks: creating visibility in untapped segments, breaking into net-new accounts, staying front of mind across long buying cycles. Best activated when entering new markets, targeting untouched accounts, or when leadership-level visibility is needed to elevate the proposition upstream.

Educate playbooks: reshaping perceptions, building trust with buying groups, proving differentiation against entrenched competitors. Best activated when accounts face entrenched competitors, when outdated brand perceptions block growth, or when buying groups are fragmented and struggling to build consensus.

Influence playbooks: progressing live opportunities, deepening stakeholder coverage, protecting deals from risk, re-engaging closed-lost accounts. Best activated when deals stall or slow, when executive conviction is missing, or when objections surface late in cycle.

Commit playbooks: last-mile decision alignment, executive value validation, driving deal closure. Best activated when the case is built but consensus is incomplete, or when a final barrier between marketing and closed revenue remains.

Each playbook contains account intelligence, a personalized value proposition and messaging framework, a personalised content and creative asset, a proven activation strategy, and consultant-led delivery support.

  • Phase 5: Multi-threaded activation

The most complex — and most valuable — deals involve multiple stakeholders across multiple functions.

Great ABM agencies build multi-threaded engagement frameworks that address each layer of the buying group simultaneously: cluster-level personalisation for shared industry challenges, account-level personalisation for specific organisational needs, DMU personalisation for the collective decision-making unit, and stakeholder-level personalisation for individual executives.

The ABM maturity problem nobody in the ABM industry talks about

There are roughly three groups of companies running ABM programs.

  • A third are exploring ABM for the first time

  • A third are in their first year

  • And a third are twelve months or more in to their ABM strategy

The first two groups are excited, energized, and full of ambition. The third group is stuck. Not failing, not quitting - just plateauing.

The pilot worked. Leadership bought in. A few deals came through. But now they're asking:

  • Are we measuring the right things?

  • What does mature ABM actually look like?

  • How do we scale beyond one region?

  • How do we get Sales to genuinely engage?

  • Where does AI fit in practically - not theoretically?

Nobody warned them about this phase.

Because the ABM industry is obsessed with getting started - "launch your ABM program in 30 days," "the beginner's guide to ABM."

Nobody is talking to the teams who already launched and are now asking: now what?

ABM success can become ABM failure. The moment it starts working across a region or business unit, others want to replicate it. Without a shared playbook, methodology, and operating model, each team improvises.

 

The program spreads faster than the philosophy. And before long, the thing that was working isn't anymore.

This is why ABM maturity - and the infrastructure to support it - is where the best agencies earn the relationship. Not in the pitch, but in what they do for clients who have proven the concept and need to make it work at scale. The questions that define mature ABM look very different from the launch questions:

  • How do we move from silo ABM to company-wide ABM?
  • How do we build an ABM Centre of Excellence?
  • How do we align Sales and Marketing around growth-driving metrics — not the ones we used in year one?
  • How do we apply AI across the full ABM lifecycle in ways that are practical and measurable?
  • How do we make ABM part of the entire GTM motion - not a side project?

ABM pilots don't fail because the strategy is wrong. They fail because teams aren't built to scale it.


ABM Playbook

What great ABM actually looks Like

The difference between ABM as a concept and ABM as a business outcome is measurable. Three examples illustrate what great execution produces:

The challenge: A major industrial software company known to one of the world's largest pharmaceutical firms for a single product.

The objective: Reposition AVEVA as a strategic partner capable of enabling GSK's Factory of the Future vision. Through a 1:1 ABM program engaging 8 DMUs across Operations, Manufacturing, IT, and Executive Leadership: 46 new stakeholder relationships, 2,000+ account microsite views, and a $9M opportunity pipeline built with a single account. AVEVA's ABM team was recognised as the Forrester B2B Program of the Year.

A blended 1:Many/1:Few program targeting 86 accounts across the automotive sector, focused on CMOs, CTOs, and Data Officers.

Result: 86 accounts engaged, 15+ meetings booked, 6 sales opportunities achieved (including Nissan, McLaren, PSA Group, Fiat, and AA), and $2M pipeline generated in 120 days.

Rakuten Advertising and CPG Accounts

A digital-first ABM program combined with social selling, targeting three strategic accounts across five territories. Result: engagement across all three countries, a 66% workshop conversion rate with Unilever and P&G, and a €MM Media Brand Partnership developed with Unilever.

These results share a common thread: they came from agencies that invested heavily in account intelligence before committing to activation, built value propositions from insights rather than assumptions, and deployed multi-channel, multi-threaded program aligned to buying group dynamics - not single-channel campaigns chasing MQLs.


The AI question: Human-first, AI-fast

AI has entered ABM - and the agencies handling it well are doing so with discipline. The pattern worth avoiding is increasingly visible: lazy prompting with no context, faster output but fuzzier insight, more content but less commercial relevance, tools everywhere but a nagging lack of confidence.

AI only works for ABM when practitioners know precisely where it fits. The use cases that are actually working:

  • AI-validated ICP and buying group development
  • AI-driven account selection and prioritisation based on fit and intent signals
  • AI-accelerated account research that surfaces insights manual research overlooks
  • AI-enabled value proposition development tailored to specific account needs and buying group dynamics
  • AI-powered personalisation at scale that preserves relevance without the 1:1 effort

The framework that characterises the best agencies: Human-first. AI-fast.

Strategy and judgment remain the domain of experienced practitioners. AI compresses the distance between intelligence and execution. The "north star" - the strategic intent, the account understanding, the relationship ambition - is never outsourced to a model.


How to evaluate an ABM Agency: The seven criteria that matter

Across Forrester, Gartner, Momentum ITSMA, and direct practitioner guidance, seven evaluation dimensions emerge consistently for assessing ABM agency quality:

1. Revenue-tied measurement

Can the agency demonstrate how they attribute pipeline and revenue to specific account-level activities? With real client examples? If not, they are running demand gen under an ABM label.

2. Sales-marketing alignment capability

Can the agency facilitate joint account planning, shared goal-setting, and integrated reporting? Agencies that operate in isolation from Sales are structurally unable to deliver ABM.

3. Strategic sophistication across ABM tiers

Do they recommend the right model (1:1, 1:Few, 1:Many) based on your deal size, sales cycle, and growth stage? One-size-fits-all thinking is a red flag.

4. Technology-agnostic integration

Do they work with your existing CRM, MAP, and ABM platforms without creating dependency on proprietary tools?

5. Account intelligence depth

How do they develop insights? Are they genuinely mapping buying groups, understanding organisational dynamics, and building account-specific value propositions - or using firmographics as a shortcut?

6. Scalability architecture

Do they build for scale from the start? Playbooks, frameworks, and training that build your team's internal capability over time?

7. Transparency and honest counsel

Are they honest about what ABM requires? Do they tell you when you're not ready? The agencies worth working with tell you what you need to hear, not what you want to hear.


FAQs: What makes a great ABM agency in 2026

  • What is an ABM agency?

An ABM (Account-Based Marketing) agency is a specialist B2B marketing partner that helps organizations design, build, and execute account-based go-to-market programs.

Unlike generalist marketing agencies, ABM agencies focus specifically on identifying and engaging high-value target accounts through personalized, multi-channel programs that align sales and marketing around shared revenue goals. The best ABM agencies operate as strategic partners - combining account intelligence, value proposition development, playbook design, and measurable execution - rather than simply running campaigns on behalf of clients.

  • What does a great ABM agency do differently from an average one? 

A great ABM agency treats ABM as a strategic go-to-market discipline — not a campaign tactic or a technology deployment.

The key differences: great agencies diagnose organizational readiness before proposing solutions; they build value propositions from genuine account intelligence rather than assumptions; they engage buying groups not contacts; they measure pipeline and revenue impact not impressions; and they invest in building the client's internal ABM capability rather than creating long-term dependency. Average agencies run targeted advertising and call it ABM.

  • What should you look for when choosing an ABM agency?

The seven most important evaluation criteria when choosing an ABM agency are: revenue-tied measurement capability, proven sales-marketing alignment methodology, strategic sophistication across ABM tiers, technology-agnostic integration with your existing stack, depth of account intelligence methodology, scalability architecture for growth beyond the pilot, and transparent honest counsel about what ABM requires.

The single most important test: can the agency demonstrate, with real client examples, how they attribute pipeline and revenue to specific account-level activities? If not, they are running demand gen.

  • How do you know if an ABM agency is actually doing ABM? 

The clearest signals: they ask about your organizational readiness before your budget; they want to understand your buying groups and deal dynamics before proposing tactics; they measure account engagement, pipeline influence, and revenue - not clicks, impressions, or MQLs; they involve your Sales team from day one; and they build personalized value propositions from account research rather than adapting generic brand messaging.

The most common failure mode in the market is agencies running programmatic advertising targeted at account lists and presenting it as ABM. Real ABM requires strategic depth, sales alignment, and genuine account intimacy.


  • How much should you expect to invest in an ABM agency? 

ABM investments typically range from $50,000-$200,000. Modern ABM agencies may offer different delivery models where they provide co-delivery or full delivery with dedicated resourcing and a complete ABM engine built and run for the client. The right investment level depends on your ABM maturity, account tier complexity, internal capacity, and growth ambitions. The more important question is not how much to invest but what you are investing in - outcomes, speed, and scale are what justify the spend.

  • What is the most common reason ABM agency engagements fail?

ABM agency engagements most commonly fail for four reasons:

- The organization was not ready for ABM before the engagement started (insufficient sales-marketing alignment, undefined success metrics, or no leadership conviction)

- The agency does not have sufficient experience in modern ABM

- The sales teams were not genuinely involved in account planning and execution

- The program was measured on campaign metrics rather than business outcomes.

Forrester research identifies that 56% of opportunities handed off to sales fail to close - underscoring that the marketing-sales gap, not the quality of campaigns, is usually the critical failure point.

  • How long does it take for ABM to deliver results?

ABM timelines depend heavily on deal complexity, account maturity, and programme design. Awareness and brand perception shifts in target accounts can be measurable within 90 days.

Pipeline influence and new stakeholder engagement typically become visible within a 90–180-day window.

Revenue impact from enterprise ABM programs is typically most clearly attributable at the 6–18 month mark, given the length of enterprise sales cycles.

Agencies that promise faster revenue results without this context are typically measuring activity, not impact. The best ABM programs are designed for long-term account relationships, not short-term campaign results.

  • What is the difference between ABM and demand generation?

Demand generation is designed to create broad awareness and generate leads at volume, typically measured by MQLs, form fills, and pipeline quantity.

Account-based Marketing is a strategic go-to-market approach focused on a defined set of high-value target accounts, measured by account engagement, relationship depth, pipeline quality, and revenue influence. ABM requires genuine collaboration between sales and marketing, account-level intelligence, personalised value propositions for specific buying groups, and measurement tied to business outcomes.

The most common mistake in the market is running demand generation programmes at account lists and calling it ABM.

  • What role does AI play in ABM agency work in 2026?

In 2026, AI plays a significant and growing role in ABM execution - but the best agencies apply it with discipline rather than enthusiasm.

The use cases delivering genuine value include: AI-validated ICP and buying group development, AI-driven account selection and prioritisation, AI-accelerated account research, AI-enabled value proposition development, and AI-powered personalization at scale.

The framework that defines best practice is Human-first, AI-fast - meaning strategic judgment, account intimacy, and relationship development remain in the hands of experienced practitioners, while AI compresses the time between insight and execution.

  • When should a company build internal ABM capability versus using an agency?

Most organizations benefit from both simultaneously rather than choosing between them. An ABM agency brings immediately deployable expertise, proven frameworks, and specialist capability that would take years to build internally. The best agency relationships are structured to transfer that expertise to the client over time — building internal ABM practitioners through training, co-delivery, and knowledge transfer. The goal of a great agency engagement is to make itself progressively less necessary while leaving the client with a scalable internal ABM capability. Companies that have moved ABM from pilot to company-wide programme typically combine a Centre of Excellence for internal governance and methodology with selective external agency support for specialist execution and new market development.

What metrics should an ABM agency be held accountable for? The metrics that matter in ABM are different from standard marketing metrics. An ABM agency should be held accountable for:

- Account engagement scores (are the right people in target accounts engaging?)

- New stakeholder access (how many new relationships are being built within accounts?)

- Pipeline influence (what proportion of pipeline in target accounts has been touched by ABM activity?) 

- Deal velocity (are ABM-covered accounts closing faster?)

- Win rate (are ABM-covered accounts converting at a higher rate?)

- Revenue impact (what is the measurable contribution of ABM to closed revenue?).

Agencies measured on impressions, clicks, or MQL volume are not running ABM programs.

  • What questions should you ask an ABM agency before hiring them?

The ten questions most likely to reveal the quality of an ABM agency:

(1) How do you assess whether we are ready for ABM?

(2) How do you develop account intelligence - what does your research methodology look like?

(3) How do you build a value proposition for a specific account?

(4) How do you involve our sales team in the program?

(5) How do you measure ABM success - with a real client example?

(6) What does your playbook methodology look like across different buying stages?

(7) How do you distinguish between 1:1, 1:Few, and 1:Many ABM, and how do you decide which model fits us?

(8) What happens when the program isn't working - how do you diagnose and adapt?

(9) How do you build our internal capability over the course of the engagement?

(10) What does great look like at 6 months, 12 months, and 24 months?
