Disclosure and methodology
Kiin is on this list, ranks itself first and publishes it. Facts about the other fourteen agencies were read from each agency's own website: for agencies already reviewed in other Kiin comparisons, in September 2026, and for Inverta and Heinz Marketing, and the ABM checks on Directive, Ironpaper and Refine Labs, on 16 October 2026. Where something is not stated, the entry says so. Nothing here is paid placement.
Scored on: whether the agency runs named-account programmes as a practice or relabels demand gen · which tier (1:1, 1:few, 1:many) it is built for · whether sales works the accounts marketing opens · pricing transparency · results published with numbers. Not scored on: size, awards, design. The cost data on this page comes from Kiin Labs, the research arm behind our benchmark reports: $60M+ of LinkedIn spend across 1,000+ advertiser accounts, 22,942 campaigns, 12 months to 7 September 2026, LinkedIn Audience Network excluded, with the narrower cuts labelled where they are used.
The 15 agencies, grouped by the job they do
Every entry follows the same record: location, services and channels, who it is for, scale, pricing, then what that means for a buyer, the results the agency itself publishes, named clients and the tradeoff. Kiin comes first. Entries 2 to 8 are enterprise programme agencies, 9 to 12 are mid-market specialists that connect ABM to sales, and 13 to 15 are performance agencies whose account work sits inside a wider paid media programme. Kiin's own position, stated plainly: a LinkedIn-led B2B paid media agency that runs ABM as named-account targeting plus retargeting plus outbound, not a full-service ABM consultancy.
1. Kiin: best for LinkedIn-led one-to-many ABM with outbound, for B2B SaaS
ABM here means named-account LinkedIn campaigns, retargeting and outbound timed to ad engagement, with no intent-data resale, direct mail or events. Published results: Storysnap, $3M+ influenced pipeline and $1.28M closed won; Lumi AI, blended cost per lead from $455 to $176. Clients: Lead Forensics, MarketerHire.
Tradeoff: we publish this list; and for twenty strategic accounts that need bespoke research and executive events, an enterprise agency further down this list is the better buy.
2. Agent3: best for scaled enterprise programmes across all three tiers
The benchmark for enterprise ABM run at scale, and one of the few agencies here with a revenue number on the record. Published results: $58M of pipeline influenced at a 116x ROI for Splunk; Expereo demand targets beaten by 125%. Named clients: Splunk, Salesforce, Adobe.
Tradeoff: built for enterprise buying committees; a Series B company with a 40-account wish list will be buying more programme than it can use.
3. Inverta: best for US enterprise ABM run on an ABM platform
An ABM specialist that starts with the technology layer: Demandbase is the platform it lists, and its case studies are measured in pipeline rather than leads. Published results: Procore drove 75% of its outbound pipeline from ABM; Sysdig raised marketing-sourced contract sizes by 36%. Named clients: Procore, Sysdig, Actian.
Tradeoff: platform-led ABM assumes an ABM platform licence alongside the fee, so price both together; the one-to-one versus one-to-many model is not stated on the site.
4. Momentum ITSMA: best for building an ABM function rather than buying a campaign
The firm that codified account-based marketing, now with Accenture Song's creative and technology scale behind it, so the fit is a company standing up or repairing an ABM centre of excellence. No client results with numbers appear on the pages read, and clients are not named.
Tradeoff: advisory leads and media follows; a team that needs LinkedIn campaigns live this quarter should look elsewhere on this list.
5. strategicabm: best for a documented ABM framework you can run, share or learn
The most process-led agency on this page, which makes it a sound first partner for a team that wants to own the method afterwards. Result on record: a programme that won Forrester's 2025 B2B Program of the Year. Publishes a monthly ABM magazine and two podcasts, so its thinking can be inspected before a call.
Tradeoff: the framework is the product; buyers looking for a single bold creative idea will find the process rigid.
6. The Marketing Practice: best for enterprise brand-to-demand programmes with a pipeline figure attached
The pitch is coherence: one programme instead of separate brand and demand budgets. Published result: $13M of pipeline credited to the Thomson Reuters CoCounsel launch. Other named clients: AWS and ServiceNow. For a $100M+ company launching into named enterprise accounts it belongs on the shortlist.
Tradeoff: enterprise scale, minimums and cadence; a scale-up will be a small client there.
7. Ledger Bennett: best for enterprise ABM run across the US and UK
Its published work is enterprise ABM: running the complexity of a programme for Trend Micro and reshaping Canon's B2B marketing. The US growth ranking suggests the model travels across the Atlantic, which matters to a buyer with sales teams in both. No quantified result is published on the pages read. Named clients: Canon, Trend Micro.
Tradeoff: the portfolio is enterprise ABM, so a smaller demand generation brief sits outside what it shows; ask for a comparable client before signing.
8. Transmission: best for multi-region enterprise go-to-market with ABM inside it
Transmission suits the buyer whose account programme is one stream of a global launch rather than a standalone engagement. It publishes its own buyer research, including a study of Gen X and Gen Z B2B buyers and "The Yes Advantage" on behavioural biases. No numeric client result is published on the pages read. Named client: Qualcomm (Snapdragon X Elite).
Tradeoff: enterprise minimums; a $10k-a-month media budget is not the shape of work it is built for.
9. Ironpaper: best for US content-led ABM on long, complex sales cycles
Ironpaper treats ABM as buyer education: research the committee, publish what it needs at each stage, and hand sales the intelligence to work the account. Deal-based ABM, aimed at opportunities already open, is an option few agencies name. A featured case reports an 86% MQL increase over six months. Named clients: Steelcase, Mobilewalla, Solartis.
Tradeoff: content-first pace; paid media supports the programme rather than leading it, so expect months, not weeks, before pipeline.
10. Heinz Marketing: best for ABM and ABX tied to a sales pipeline method
Heinz frames ABM through its Predictable Pipeline Method: target account selection, personalised engagement and coordinated sales and marketing plays. That sales-side emphasis suits a team whose problem is converting engaged accounts, not reaching them. No quantified results on the pages read. Named clients: Qualys, Nutanix, Hyland, Uptempo, EDB.
Tradeoff: consulting-led; confirm who runs the paid media day to day before you sign.
11. Digital Litmus: best for ABM built on a HubSpot revenue engine
The argument is that ABM fails on disconnected systems, so the CRM, routing, scoring and reporting are designed first and the account programme runs on top. That makes it a sensible first ABM partner for a company whose real gap is measurement: every account touch lands where a revenue team can see it. Published case: Cambridge Spark, an FT 1000 company, rebuilt on HubSpot. No quantified ABM result is published on the pages read.
Tradeoff: HubSpot-centred; on Salesforce or Marketo the method still applies but the delivery partner is the wrong one.
12. Punch!: best for ABM where SDRs work the accounts using owned intent data
Punch! closes the gap most account programmes leave between marketing warming an account and someone actually calling it: intent data it owns flags the account, and SDRs on the same team work it. The fit is a seller that wants account-based marketing and account-based selling from one supplier, with a single number for meetings booked. Client names and numeric results are not published on the pages read.
Tradeoff: enterprise minimums, and the intent data is the product, so ask how it is sourced, how often it is refreshed and how often it is right.
13. Refine Labs: best for Series B+ demand programmes that also target existing accounts
Not an ABM agency by label, but its expansion work runs media against named customers and accounts, which is ABM in practice. Portfolio averages: +41% high-intent demo requests, +33% pipeline value. Named clients: Clari, Cognism, Algolia, BeyondTrust.
Tradeoff: $14,000 a month before media screens out most companies under $20M ARR, deliberately.
14. Directive: best for US enterprise performance programmes built around the ICP
Directive is here as the scaled US performance option. Its homepage frames the work around how the ICP discovers, evaluates and decides, and does not list ABM as a named service. Named clients: Calendly, Gong, ZoomInfo, Adobe, Cisco, Samsung. No ABM-specific result is published on the pages read.
Tradeoff: if you need one-to-one account plays, ask for an ABM case study first; a $10k-a-month account will not get its most senior people.
15. Powered by Search: best for B2B SaaS that wants ABM inside a paid, SEO and HubSpot programme
ABM is one lever in a stacked programme rather than a standalone practice, which suits a SaaS team that wants account targeting, search and CRM operations fixed by one partner. Case studies carry pipeline numbers: an $11.1M SEO pipeline for a data-privacy SaaS and +15% MRR for a mid-market client. Named clients: Elastic, Basecamp, Varonis, SentinelOne.
Tradeoff: a full-stack engagement; with SEO and content already covered you are buying more than the ABM you came for.
Full comparison: model, channels, pricing and regions
Columns chosen for an ABM buyer: the account model each agency is built for, the channels it runs itself, whether the price is on the website, and where the team sits. "Not stated" means the agency's own site does not say.

| Punch! | Mid-market and enterprise sellers | 1:few, 1:many plus SDRs | Intent data, email, phone, LinkedIn | On enquiry | UK |
| Refine Labs | Series B+, $50M+ ARR | Media to existing accounts | LinkedIn, Google, YouTube, Meta, CTV, OOH | Yes: from $14,000 a month | US |
| Directive | Funded and public B2B software | ICP-led; ABM not named | Paid, programmatic, content, RevOps | No | Orange County; six offices |
| Powered by Search | B2B SaaS | ABM within a stacked programme | Paid, SEO, content, HubSpot RevOps | No | Not stated |
Which ABM agencies connect programmes to sales revenue
"Connected to revenue" is the most common claim on an ABM agency homepage and the least often evidenced. The test is simple: does the agency publish a pipeline or revenue figure, with a client name, from its own case studies? Of the fifteen on this list, these do:
- Agent3: $58M of pipeline influenced at a 116x ROI for Splunk.
- The Marketing Practice: $13M of pipeline credited to the Thomson Reuters CoCounsel launch.
- Inverta: Procore drove 75% of its outbound pipeline from ABM; Sysdig raised marketing-sourced contract sizes by 36%.
- Refine Labs: +33% pipeline value as a portfolio average across clients.
- Kiin: Storysnap, $3M+ influenced pipeline and $1.28M closed won.
The rest publish engagement, MQL or programme outcomes, or nothing numeric on the pages read. That is not proof they cannot connect ABM to revenue, but it moves the burden onto the sales call. Ask for an account-level number: how many target accounts reached pipeline, at what value, against what list size. If the answer arrives in leads and MQLs, the programme is demand generation with a list attached.
One measurement limit applies to every agency here, Kiin included. LinkedIn reports engagement by company, not by person, so the honest unit for an ABM report is the account: companies reached, companies engaged, companies in pipeline. Any agency claiming to tell you which individual at an account saw your ad is describing something LinkedIn does not provide.
The best ABM agencies for beginners and first programmes
A first ABM programme fails for predictable reasons: the account list is a wish list rather than an ICP, nobody owns follow-up, and the budget is judged on cost per lead in month two. The right first agency reduces the number of those things that can go wrong at once.
- If you want to learn the method and keep it: strategicabm, which offers delivered, co-delivered and taught engagements.
- If your CRM cannot yet tell you which accounts engaged: Digital Litmus, which builds the HubSpot foundations first.
- If sales follow-through is the weak link: Heinz Marketing or Punch!, both built around the sales side of the play.
- If you want a fixed cost and a short commitment: Kiin, at a published flat fee with a three-month pilot, running the list on LinkedIn where the account targeting is native.
For most first programmes the sensible tier is one-to-many on a list of a few hundred companies you can already name, not one-to-one on twenty you hope to win. One-to-one needs research, content per account and executive time that a first programme rarely has. A step-by-step version of the LinkedIn build is in our LinkedIn ABM guide.
Integrated ABM programmes vs full-service strategy and execution
Buyers asking for "integrated ABM" usually mean one of three different things, and the agencies on this page split cleanly along them.
- Strategy and execution under one roof. One team sets the account strategy, builds the creative, runs the media and reports on pipeline: Agent3, The Marketing Practice, Ledger Bennett, Transmission, Ironpaper and Inverta. This is the full-service shape, and it carries enterprise minimums.
- Strategy first, delivery shared. The agency designs the programme and either trains your team or delivers alongside it: Momentum ITSMA, strategicabm and Heinz Marketing. Best when you intend to own ABM internally within a year.
- Channel-led execution against an account list. The agency runs the media and the follow-up motion against a list you supply: Kiin, Refine Labs, Directive and Powered by Search, with Punch! adding SDRs and Digital Litmus adding the CRM layer.
None of these is better in general. The mistake is buying the first when you needed the third, which costs an enterprise retainer for a list LinkedIn could have reached at a fraction of the fee, or buying the third when the real gap is account strategy nobody has written. If you are choosing for a large account base, our enterprise ABM agencies comparison goes deeper on that end of the market, and the Kiin ABM service page sets out exactly what we run.
ABM for B2B lead generation: what an agency can and cannot promise
Account-based marketing and lead generation pull in different directions, and the data says so. In Kiin Labs' lead gen forms study, uploaded lists are 42% of all lead gen spend and are the dearest audience on LinkedIn for a form fill. That is not a reason to drop the list; it is a reason to judge it on meetings and pipeline from named accounts rather than on cost per lead.
Two practical rules follow. First, the format matters more than the list: a demo form completes at 2% in the feed and 40% in a message ad, so an ABM agency that only runs single image lead forms against a list is choosing the most expensive combination available (LinkedIn Lead Gen Forms Benchmarks 2026). Second, narrowing helps only in one specific way, which the next three sections measure.
Does a tighter target list buy better engagement? Audience Report No. 7
The default ABM instinct is to narrow: fewer accounts, tighter titles, a more relevant audience. Kiin Labs tested that instinct inside the same advertiser accounts, comparing campaigns aimed at fewer than 30,000 people with campaigns aimed at 30,000 or more, so that account quality cannot explain the difference.
| Under 30,000 people vs 30,000+, same advertiser | Result | 95% interval | Advertisers higher | Significant? |
|---|---|---|---|---|
| CPM | +32.1% | [+19.2%, +52.0%] | 165 of 245 | Yes |
| Landing page click-through rate (LP CTR) | +0.8% | [−8.0%, +10.9%] | 123 of 245 | No |
| Cost per landing page click (LP CPC) | +32.2% | [+19.0%, +47.2%] | 159 of 245 | Yes |
n = 245 advertisers that ran both a narrow and a broad cold audience. Median of per-account ratios, bootstrap intervals, 4,000 resamples. Source: LinkedIn audience targeting: 2026 benchmarks (Kiin Labs Report No. 7): 491 advertisers, $34.8M of LinkedIn spend, 10,248 campaigns, one year, US dollar accounts, Audience Network excluded.
A narrow cold audience costs a third more per landing page click and the click rate does not move. Relevance is the reason agencies give for tight targeting, and on this panel relevance does not show up. Our UK ABM comparison found the same shape for named-company targeting across 72 paired accounts: a 28% better click-through rate, bought with a 75% CPM premium, so each click still costs 23% more.
For a buyer, the implication is a question to put to any agency on this list: how many people will our programme actually target once titles are applied, and why that number? If the answer is a few thousand on a cold audience, you are paying the premium without the benefit.
The one narrowing that pays: filtering people inside a known account list
The same report found the exception. Kiin Labs identified 317 matched audience segments, the identical uploaded list, that advertisers had run both bare and with a job title, seniority or function filter added on top. Because the list is held constant, only the layer changes.
| Same list, layered vs bare | Result | 95% interval | Segments higher | Significant? |
|---|---|---|---|---|
| CPM | +30.4% | [+14.6%, +46.3%] | 197 of 317 | Yes |
| Landing page click-through rate | +38.6% | [+17.3%, +107.5%] | 136 of 227 | Yes |
| Cost per landing page click | −26.2% | [−34.1%, −20.9%] | 77 of 227 | Yes |
| Cost per lead | −6.7% | [−56.6%, +65.3%] | 25 of 51 | No |
n = 317 segment pairs for CPM, 227 with landing page clicks on both sides, 51 with leads on both sides. Source: Kiin Labs Report No. 7, same panel as above.
Layering costs 30% more per impression and earns 39% more click-through, which nets a landing page click 26% cheaper. This is the mechanism that makes account-based targeting on LinkedIn efficient: the list decides which companies matter, and the layer decides who inside them is worth paying for. A bare account list is an unfinished audience. Lists themselves are not cheap, which is why the layer matters: paired within 165 advertisers, an uploaded list runs 19.7% more per landing page click than cold native targeting with no better click-through.
Is retargeting the engaged accounts cheaper than cold? Not inside the same advertiser
Most ABM proposals assume the second stage, retargeting the people at target accounts who engaged, is where costs fall. Across accounts it looks that way. Within the same advertiser it does not.
| Retargeting vs cold native targeting, same advertiser | Result | 95% interval | Significant? |
|---|---|---|---|
| CPM | +3.1% | [−8.4%, +23.3%] | No |
| Landing page click-through rate | +16.1% | [−0.7%, +27.1%] | No |
| Cost per landing page click | +1.2% | [−20.4%, +23.9%] | No |
| Cost per lead | −7.1% | [−46.4%, +218.5%] | No |
| Engagement rate | −10.1% | [−31.0%, +8.0%] | No |
n = 156 advertisers that ran both retargeting and cold native campaigns. Every interval spans zero. Source: Kiin Labs Report No. 7, same panel as above.
Retargeting looks cheap in cross-account tables because the advertisers who use more of it tend to be better operators. Paired, it is indistinguishable from cold targeting on every measure. That does not make retargeting pointless in an ABM programme; it means its job is sequencing, moving an account from seeing you to talking to you, not lowering your cost per click. An agency that budgets retargeting as the cheap half of the plan is working from the cross-account illusion.
