--- title: "ABM Agency for B2B: Account-Based Systems You Own | OneGTM" description: "An ABM agency that builds account-based marketing systems on your data: tiered account lists, buying committees, intent signals, matched audiences, and outbound." url: https://getaob.com/abm-agency --- # ABM agency: account-based marketing systems built on your data OneGTM is an **ABM agency** for B2B teams that sell to a defined set of accounts. I build the account list and tiers, map the buying committee at each account, watch for intent and buying signals, push matched audiences to your ad platforms, and run multi-threaded outbound so sales and marketing work the same accounts at the same time. By [Garrett Wolfe](https://garrettawolfe.com), founder of OneGTM. Updated November 1, 2026. Key takeaways - ABM is a list decision first. A tiered account list your sales team agrees with matters more than any platform. - Map the buying committee. Most B2B deals need several people, so reach several people. - Signals decide which accounts get attention this week, so effort follows real activity. - Matched audiences and outbound should hit the same accounts in the same weeks. - Measure ABM by account: engagement, meetings, and pipeline per tier, not clicks. ## What an ABM agency should build ### Target account list and tiers Accounts scored for fit and sorted into tiers, signed off by sales before anything runs. Size it with the [TAM calculator](https://getaob.com/tam-calculator). ### Buying committee mapping The economic buyer, champion, users, and blockers at each tier one and two account, found and verified. ### Intent and signals Website visits, hiring, job changes, funding, and third-party intent, matched to the list. See [buying signals](https://getaob.com/buying-signals). ### Matched audiences LinkedIn, Google, and Meta audiences built from the list and the committee, refreshed as it changes. Your paid team or agency runs the ads. ### Multi-threaded outbound Email and LinkedIn to several people per account, with messages written by role. ### Rep views and alerts CRM views and Slack alerts that show which accounts are active today and why. ## ABM tiers: one-to-one, one-to-few, one-to-many | Tier | Accounts | What they get | | --- | --- | --- | | One-to-one | A few dozen of your best-fit, highest-value accounts | Research per account, custom messaging, executive outreach, sometimes direct mail | | One-to-few | Clusters of similar accounts, often by industry or use case | Messaging per cluster, multi-threaded outbound, targeted ads | | One-to-many | The rest of the scored list | Signal-triggered outbound and broad matched audiences | Comparing agencies?

Many teams run a platform and still need someone to build the list and the outbound around it. ## What an ABM build looks like 1. **List:** Score the market, pick tiers with sales, and freeze the list for the quarter. 2. **Committee:** Find and verify three to six people per tier one and two account. 3. **Signals:** Wire website visitors, hiring, and job changes to the list, with Slack alerts to account owners. 4. **Audiences:** Push the list and the committee to LinkedIn and Google for your paid team. 5. **Outbound:** Sequences by role and tier, timed with the ads. 6. **Reporting:** Engagement, meetings, and pipeline per tier, reviewed every two weeks. For Patlytics, an AI patent platform, the build covered intent signal aggregation and BDR enablement alongside inbound and outbound. ## ABM agency FAQ ### What does an ABM agency do? An ABM agency helps B2B companies focus sales and marketing on a defined list of target accounts. That usually means building and tiering the list, mapping buying committees, monitoring intent, running targeted ads and outreach, and reporting by account. ### What is account-based marketing? Account-based marketing is a B2B approach where sales and marketing pick a set of high-fit accounts and coordinate ads, outreach, and content to reach several people at each one, instead of generating as many individual leads as possible. ### Do I need an ABM platform to run ABM? No. A scored account list, intent and signal data, matched audiences on LinkedIn and Google, and multi-threaded outbound can run on your CRM and existing tools. A platform helps once the program is large and someone owns it. ### Does OneGTM run ads? No. OneGTM builds the account lists, audiences, signals, and outbound. Your paid team or paid media agency runs the ads against those audiences. ### How do you measure ABM? By account and tier: share of target accounts engaged, meetings, pipeline created, and win rate, compared against accounts outside the program. ### How many accounts should be in an ABM program? It depends on deal size and team capacity. A common shape is a few dozen one-to-one accounts, a few hundred one-to-few accounts in clusters, and a larger one-to-many tier worked by signals.
