Account-based marketing is easy to buy badly. Plenty of programs sold as ABM turn out to be broad lead generation with an account list attached, and the sales team stops paying attention within a quarter. The agency you pick decides whether ABM becomes a pipeline engine or an expensive advertising line item.
This list is for B2B marketing and revenue leaders at US companies, or companies selling into US accounts, who want a partner that can choose the right accounts, reach the buying committee and tie the work to opportunities. Every firm below has a US headquarters or a US address and a dedicated ABM service described on its own website. After the list you get selection criteria, first-call questions and red flags you can use in any evaluation.
Disclosure: this list is published by Lemniscate Growth, which is included.

How we chose
- Verified operating website: the site loads and shows 2025 or 2026 activity, such as dated articles or a current copyright line.
- US presence: a US headquarters or a US address stated on the firm's own site.
- A dedicated ABM service: a page or service section describing account-based marketing work, not a passing mention in a list of tactics.
- B2B specialization evidence: language about target account selection, buying committees, sales alignment or account-level measurement.
- Clarity about method: a visible explanation of how accounts are selected, engaged and measured.
No firm paid to be included. Inclusion is based on public information on each firm's own website, reviewed in September 2026. The order after entry 1 is not a ranking.

How to choose an account-based marketing agency
Start with account selection, not channels
The account list is the program. Ask how the agency builds it: closed-won and lost-deal analysis, firmographic fit, intent or trigger signals, and whether your team can actually reach the buying group. An agency that jumps straight to ad formats has skipped the step that decides your results.
Match the tier model to your deal sizes
One-to-one ABM only makes sense where deal value can pay for custom research and content. One-to-few works for clusters of similar accounts, and one-to-many is programmatic targeting with account-level reporting. Ask the agency how many accounts it would put in each tier for your business, and why.
Insist on buying committee coverage
Enterprise deals rarely close on one champion. A good partner maps the roles that influence the purchase, such as economic buyer, technical evaluator, end user and procurement, and reports how many of those roles are engaged at each account. Form fills from a single junior contact are not ABM progress.
Check the sales alignment mechanics
ABM fails quietly when sales does not follow up. Look for agreed account plans, a named owner for each tier-one account, a follow-up expectation when an account shows engagement, and a standing weekly or biweekly review between marketing, sales and the agency.
Decide how much direct outreach you need
Programs built only on advertising and intent data can take a long time to create conversations. Programs that combine LinkedIn, email, calling and events with account advertising usually produce meetings sooner. Pick an agency whose strengths match the mix you need.
Measure at the account level
Useful ABM reporting tracks engaged accounts by stage, meetings and opportunities created at target accounts, pipeline value, win rate and deal size compared with non-target accounts. Clicks and impressions are inputs, not outcomes.
Be realistic about time
Enterprise sales cycles are long. Agree on leading indicators for the first 90 days and on when pipeline and win-rate judgments are fair, so neither side declares success or failure too early.
Questions to ask on the first call
- How will you build and tier our target account list, and what data do you need from us to do it?
- How many accounts would you put in each tier for a company with our deal size and sales cycle?
- How do you map buying committees, and how many roles per account do you aim to engage?
- What share of the program is strategy, content, paid media and direct outreach?
- Which ABM, intent and CRM tools do you already work with, and do we need to buy anything new?
- What does the working cadence with our sales team look like each week?
- How do you define an engaged account, and what happens when one reaches that threshold?
- What leading indicators should we expect in 90 days, and how will pipeline be reported at six and twelve months?
- Can you walk through an ABM program you ran for a company with a similar deal size?
- Who will work on our account day to day, and how senior are they?
Red flags
- A target list of thousands of accounts described as one-to-one ABM.
- Reporting built around impressions, clicks or MQLs instead of account engagement, opportunities and pipeline.
- No plan for sales involvement beyond handing over leads.
- A platform recommendation before your ICP and account criteria are defined.
- Personalization that stops at inserting the company name into ad copy.
- Pipeline guarantees offered before the agency has seen your deal sizes, win rates and sales cycle.
- No examples of ABM work with a comparable deal size or buyer.
Next step: check whether you are ready for ABM
Before you sign with any ABM agency, confirm that your ICP, target account list and sales follow-up process can support it. A short review usually shows whether ABM, broader demand generation or a mix will produce pipeline faster for your market.
Lemniscate offers a free pipeline audit that looks at your ICP, target accounts, channels and conversion path and shows where ABM would fit. Whichever partner you choose, use the questions above to make the first call count.
