How we built this list

Execution-framed, not enterprise 1:1

We verified each agency on its own current site in July 2026: what they do, who they serve, their engagement model, and any pricing they publish. We featured shops that run account-based, signal-driven outbound you can actually buy at seed to Series A, not the enterprise 1:1 ABM programs built around six-figure paid media and named-logo events.

We run signal-based account targeting ourselves, so the read on each shop comes from knowing the work. Where an agency had no independent review sample we could trust, we left the rating off rather than invent one.

How we built this list

→ Every agency verified on its own current site, July 2026
→ Framed for account-based execution at seed to Series A, not enterprise 1:1 ABM
→ Ratings shown only where a credible independent sample exists, linked and dated
→ No affiliate links, no paid placements, no pay-to-list
→ We publish this list and we are on it. We do not rank ourselves first, and we say where we are not the fit

The real test

Enterprise 1:1, or account-based outbound?

"ABM agency" covers two very different things. Getting the wrong one is the most expensive mistake here. Two honest models, and only one of them fits an early-stage budget.

Enterprise 1:1

A coordinated program around named logos

Paid media, bespoke content, and events aimed at a few dozen target accounts, usually worked by a large sales team. Powerful when a single logo is worth a small campaign, and priced accordingly. Overkill, and out of reach, before you have that motion.

Use it when a handful of accounts justify a full program and you have the team and budget to run it.

Account-based outbound

A fit-based account list, worked on signals

Pick the accounts that match, map the buying group, and reach them on email and LinkedIn when a real trigger fires. Fewer accounts, more context, and a reason to reach out. This is the version a seed to Series A team can actually buy and run.

Use it when you have a defined account list, a small team, and want meetings from the accounts that fit.

The through-line

Almost every shop on this list runs the second model. The edge is timing: reaching the right account when a real signal fires, a funding round, a new hire, a tech change, not spraying a list and hoping. Ask any agency here two things: how do you pick the accounts, and what tells you when to reach out?

The agencies

The ABM agencies, grouped by job

Grouped by what they are best at, not ranked one to eleven. Read the group that matches where you are.

Group A

Signal-based account targeting

They pick accounts, watch for a real trigger, and reach the buying group when the timing is right. The pick when you want targeting driven by signals, not a static list, and you have the motion to hold it.

01

C17

Remote TAM · signal-triggered

A revenue-engineering firm for technically mature teams: complex, custom automation, installed so you own the data, tools, and workflows. Account targeting starts from TAM mapping, then fires on signals.

Best for

Teams with real technical maturity that want advanced, owned account-based automation.

Model & pricing (Jul 2026)

Technical build engagements, quoted per scope. Not published.

Where they're strong

High technical depth, TAM mapping and signal-triggered outreach, and a client-ownership model that leaves the system with you.

Consider elsewhere if

You want a simple, hands-off starter setup. C17 is pitched at sophisticated, technical needs.

Bottom line

The pick when your account-based needs are genuinely advanced and you have the team to hold the system.

02

Kinetyca

Remote · US Intent loops

Systemized, ops-disciplined GTM: intent loops that run from ad to booked call, with enrichment, scoring, and routing wired together around the accounts that matter.

Best for

Post-PMF B2B past roughly $1M ARR that wants disciplined, account-based GTM infrastructure.

Model & pricing (Jul 2026)

Systemized build and run, quoted per scope. Pricing not published.

Where they're strong

An operations-first approach, Clay intent loops from ad to booked call, and documented pipeline results in public case studies.

Consider elsewhere if

You are pre-PMF or pre-revenue. The model assumes an existing motion to systemize.

Bottom line

A strong pick when you want intent and account signals wired into one loop that ends in booked calls.

03

Scalantec

Berlin, DE Signals + scoring

A Berlin-based GTM-engineering agency that builds automated go-to-market systems, TAM mapping, enrichment, signal monitoring, scoring, and automated outreach, so B2B companies scale revenue without adding sales headcount.

Best for

B2B companies with PMF that want a data-driven engineered outbound system, notably DACH and European mid-market SaaS and tech.

Model & pricing (Jul 2026)

Custom, project and build-based; case studies reference multi-month engagements. Pricing not published.

Where they're strong

Clay-heavy GTM automation with signal monitoring and FIT plus engagement scoring, led by an ex-Clay founder.

Consider elsewhere if

You are pre-revenue seed, or you want published pricing and detailed channel breakdown. Those are thin.

Bottom line

A systems-builder pick for European teams that want signal monitoring and scoring wired into automated outreach.

LeadGem

Amsterdam, NL Clay · signal-based

An Amsterdam-based RevOps and outbound agency, and a Clay Certified Partner, that builds Clay-powered outbound and RevOps systems, enrichment, signal-based prospecting, LinkedIn and email automation, to turn prospecting into predictable pipeline.

Best for

B2B revenue teams that want a Clay-powered, RevOps-aligned account outbound system; sector focus SaaS, manufacturing, recruitment.

Model & pricing (Jul 2026)

Custom, consultation-led via a discovery call. Build-and-run of Clay-powered systems. Pricing not published.

Where they're strong

Signal-based prospecting with enrichment across 50+ data sources, and a Clay Certified Partner badge. Serves Benelux, the Nordics, the US, and Australia.

Consider elsewhere if

You want published pricing, independent reviews, or a tighter seed-boutique focus. Their sector and stage range is broad.

Bottom line

A Clay-native, signal-based option for European revenue teams that want RevOps and account outbound wired together.

Group B

Lean, founder-led account execution

Small teams that run account-based outbound for early-stage companies without an enterprise price tag. The pick at seed to Series A, when you want a tight account list worked on signals and a low-risk way to start.

05

Crumbs

Remote · EU Clay-based · seed

An AI-powered, Clay-based B2B lead-acquisition and outbound agency that builds, tests, and scales outbound "that does the work of 5 SDRs," without the manual hassle. Targeting runs on intent and trigger signals.

Best for

Founder-led, product-led, or small sales teams that want to add, test, and scale account outbound without hiring SDRs.

Model & pricing (Jul 2026)

A low-commitment "test drive" and a roughly two-week proof of concept, then ongoing prospecting with bi-weekly check-ins. Pricing not published.

Where they're strong

Clay-native builds with 30+ data sources, AI personalization, and intent and trigger-signal messaging across email and LinkedIn.

Consider elsewhere if

You want calling, published pricing, or a disclosed HQ and founder details. Those are not public.

Bottom line

A genuinely seed, founder-led Clay shop, with a low-commitment test drive that lowers the risk of a first account-based experiment.

Real Good GTM (that's us)

Paris · US/Europe Founder-led · signal-based

The two of us run signal-based account targeting for seed to early Series A. You get booked pipeline plus a clear read on what to scale, and you keep everything we build. Paris-based, serving the US and Europe primarily.

Best for

Seed to early Series A founders who want the two founders running signal-based outbound, plus a real read on their market, not a junior pod chasing volume.

Model

A two-month start, then month to month, no lock-in. Signals over lists, built per segment. Email and LinkedIn (Instagram on request).

Where we're strong

Founder-led delivery, signal-based rather than list-based account targeting, and a live GTM Learning Memo per ICP on what actually converts and where to scale.

Not for you if

You need cold calling, enterprise-scale meeting volume, guaranteed lead counts, or a specialist industry team. That is not us.

Straight talk

We are early and have no third-party review sample yet, so we do not show a score for ourselves. Our proof is the pipeline we have built inside companies like Palm.ai, Mindflow, CEF.AI, and Inro. If outbound is not right for you yet, we will say so on the call.

DEV Commx

Remote AI · signal-based

An AI-SDR and GTM-engineering agency that builds AI-powered GTM systems to automate signal-based prospecting, personalized multichannel outreach, and lead qualification for B2B teams.

Best for

B2B founders, RevOps leaders, and sales managers who want a done-for-you signal-based outbound system rather than hiring SDRs.

Model & pricing (Jul 2026)

Done-for-you build-and-run of an outbound system, with a free GTM audit as the entry point. Pricing not published.

Where they're strong

Signal-based prospecting on triggers like job changes, funding, tech stack, and hiring, with GPT-4, Clay, and Smartlead behind the outreach and CRM routing.

Bottom line

An assembled AI stack wrapped around signal-based prospecting and automated reply handling, for teams that want it run for them.

Group C

Full account-based systems, funded

They build and run the whole account-based engine end to end, often with Clay as the spine and RevOps in the mix. The pick when you have revenue or product-market fit and want one team to own account targeting, not a first seed experiment.

08

Understory

Atlanta, US Allbound · one ICP

Runs paid media, GTM engineering, and LinkedIn content as one "allbound" system under a single ICP, with a marquee client roster to match.

Best for

Funded B2B SaaS that wants outbound, paid, and RevOps run as one compounding motion under one account list.

Model & pricing (Jul 2026)

Retainer, with GTM engineering listed from $12,000 a month on their own site. A 4 to 6 month minimum, run by a dedicated pod.

Where they're strong

Genuine allbound integration under one ICP, an Advanced Artisan Clay partner, and clients including Clay, HockeyStack, and RB2B.

Consider elsewhere if

You need a small, single-channel, or low-budget engagement. The entry point is around $12k a month.

Bottom line

A strong pick when account-based outbound, paid, and RevOps should be one team, not three vendors.

Nebor

Amsterdam, NL Full GTM · Clay

Full-stack GTM infrastructure, outbound, demand gen, and CRM hygiene, built by operator founders with Clay as the spine. The 2026 rebrand of Utmost Agency.

Best for

Model & pricing (Jul 2026)

Implementation packages: a one-time setup fee plus monthly monitoring, quoted per scope. Pricing not published.

Where they're strong

Integrated GTM and RevOps rather than siloed channels, operator founders, and a useful comparison-content library.

Consider elsewhere if

Bottom line

The pick when you want an owned, integrated account-based stack built on Clay, not a rented campaign.

FullFunnel

Boston, US ABX · RevOps

A B2B GTM and RevOps services firm that unifies sales and marketing around demand generation, pipeline management, and customer success, and is one of the few Clay Elite Studio partners. ABM and ABX are named parts of the motion.

Best for

B2B organizations with an existing GTM motion to systematize, public tech firms and PE-backed middle-market, not pre-revenue seed.

Model & pricing (Jul 2026)

RevOps-as-a-Service in a tiered consumption model, plus project and retainer consulting. Pricing and minimums not published.

Where they're strong

Full-funnel coverage across demand gen, sales ops, and Clay data operations, with confirmed Clay Elite Studio status.

Consider elsewhere if

You want a tiny founder-scale, single-channel, or month-to-month seed engagement. This is a full GTM/RevOps shop.

Bottom line

The pick when ABM and ABX should live inside a full-funnel RevOps program, not a standalone outbound campaign.

ColdIQ

Remote · EU/US Full account engine

One of a handful of Clay Elite Studio partners, and the most visible content brand in the category. Full-service revenue engines, built and run for you around your target accounts.

Best for

Post-PMF B2B tech that wants a done-for-you, multi-channel account-based engine run end to end.

Model & pricing (Jul 2026)

Monthly retainer, three-month minimum, quoted per scope. Their done-for-you tier is gated to roughly $100k/mo revenue and up.

Where they're strong

Elite Clay build depth, a deep content and teardown library, and full-stack coverage across outbound, LinkedIn ads, and email infrastructure.

Consider elsewhere if

You are pre-revenue or want month-to-month terms. Their done-for-you tier starts above seed and asks for a three-month commit.

Bottom line

The category's most established full-service shop. Out of range, and overkill, for a first seed experiment.

How to choose

Who each one is for

Find your situation below and start with the agency next to it. A sensible starting point, not the only right answer.

Seed, want to test account outbound

Real Good GTM (that's us) to run signal-based targeting, or Crumbs for a low-commitment Clay test drive.

Post-PMF, want signals wired in

Kinetyca for intent loops to booked calls, or C17 if your needs are technical and you want to own it.

Funded, want it fully done for you

ColdIQ or Understory. Full-service teams that run the whole account engine.

Based in Europe, especially DACH

Scalantec in Berlin, or LeadGem in Amsterdam for a Clay-native, signal-based build.

Want an AI-run outbound system

DEV Commx for signal-based prospecting and reply handling run as an AI stack.

Want ABM inside full-funnel RevOps

FullFunnel for ABX plus RevOps, or Nebor for an owned, integrated stack on Clay.

Putting it together

How we'd actually choose

We run signal-based account targeting for a living, so here is the order we would run the decision in, whether or not we are on your list.

1

Rule out enterprise 1:1 first

If you do not have a large sales team and a budget for paid media around named logos, you want account-based outbound, not a six-figure ABM program. That alone removes half the "ABM agencies" out there.

2

Match the stage gate

Most full-service shops here want revenue or product-market fit. At seed, that narrows you to the lean, founder-led options with a pilot or month-to-month terms.

3

Ask how they pick and time accounts

The whole edge is choosing the right accounts and reaching them when a signal fires. Ask how they build the list and what tells them when to reach out. A good answer is specific.

FAQ

Questions people ask

What is an ABM agency?

An ABM (account-based marketing) agency focuses your go-to-market on a defined set of target accounts rather than a broad list, then reaches the buying group inside those accounts with coordinated outreach. The enterprise version is heavy 1:1 marketing with paid media and content aimed at a few dozen named logos. The version that fits seed to Series A is leaner: pick the accounts that match, watch for a real buying signal, and run account-based outbound on email and LinkedIn when the timing is right.

Is ABM worth it for an early-stage startup?

Yes, if you treat it as targeting discipline rather than an enterprise program. At seed to Series A you rarely have the budget for full 1:1 ABM with a display-ad layer, and you do not need it. What works is a tight account list built from fit plus a trigger, and outbound that lands while the signal is fresh. Skip the shops that sell six-figure enterprise ABM programs. They are built for a different buyer.

How is account-based outbound different from a normal lead list?

A normal list is a pile of titles that match a filter, worked in order until it runs out. Account-based outbound starts from the accounts you actually want, maps the buying group inside each one, and reaches them when a signal says the timing is right, a funding round, a new hire, a tech change, a product launch. Fewer accounts, more context per account, and a reason to reach out beyond the fact that they exist.

How much does an ABM agency cost?

Most work on a monthly retainer quoted per scope rather than published. The leaner, account-based-outbound shops on this list start lower and often offer a short pilot or test drive; several full-service and Clay Elite shops gate their done-for-you tier to companies already past roughly $100,000 a month in revenue. Enterprise 1:1 ABM programs run far higher again. Always confirm the current number on the agency's own site.

Do I need enterprise 1:1 ABM or account-based outbound?

Enterprise 1:1 ABM makes sense when a handful of named accounts are worth a coordinated program of paid media, events, and bespoke content, usually with a large sales team to work them. Account-based outbound makes sense when you have a defined account list, a small team, and want meetings from the accounts that fit, triggered by signals. Most seed to Series A companies want the second, not the first.

How is an ABM agency different from a lead generation agency?

A traditional lead generation or appointment-setting agency staffs SDRs who work a broad list on your behalf, and you pay largely for their activity. An account-based agency narrows the field to the accounts you want, adds context and timing, and reaches the buying group with a reason. The line blurs in practice, and many buyers end up wanting some of both, but the starting point is different: accounts and signals, not volume.
