For a full example, read the Coastal Recruiting case study: a candidate outbound engine that grew recruiter-accepted intros 4.7x in four months. The Antimetal case study is the signal build: 17 Automated Outbound deals and $2.57M in pipeline from December 2025 to May 2026. The Green Dock Partners case study is a closure-news tracker and a daily digest. Every customer result lives on our case studies page. Not sure where your gaps are? Take the free GTM scorecard first, and keep the GTM glossary handy for the jargon. Pricing a BDR team or a GTM engineer? The outbound cost calculator shows the fully loaded year-one cost. Sizing your market? The TAM calculator scores and tiers your accounts. Building it yourself? Start with our GTM playbook, the GTM engineering guide, and the buying signals guide. Learning the craft? The free GTM engineering course is an eight-week path with a project each week.

Comparing vendors for a piece of the stack? The GTM tool guides cover every category, from cold email and LinkedIn to signals, dialers, and call recording, with what we use in each.

How a build works

The full picture, from the end-to-end flow to the 12 work modules and engagement structures, is on how I work.

  • Audit (week 1): I look at your CRM, your tools, and how pipeline gets created today, then write down what to build first and why.
  • Build (weeks 2 to 6): the systems go live in your own accounts, one at a time, starting with whatever gets reps in front of the right accounts fastest.
  • Hand-off: every table, workflow, and script is documented and owned by you. Your team gets a walkthrough, and I stay on for support or an ongoing retainer if you want one.

Who this is for

  • Seed to Series C B2B companies that have product-market fit and need their first real pipeline systems.
  • Lean sales and marketing teams without a dedicated RevOps or GTM engineering hire yet.
  • Founders who want to own the system instead of renting output from an agency. For the difference between a GTM engineer and an agency, see what a GTM engineer does.

GTM engineering services FAQ

What are GTM engineering services?
GTM engineering services are the builds behind pipeline: enriching and scoring accounts, monitoring buying signals like hiring or website visits, routing leads, and running outbound and inbound automation off those signals. OneGTM delivers them as working systems in your own CRM and tools, built with Clay, n8n, HubSpot or Salesforce, and custom code.
How long does a GTM engineering build take?
Most builds take two to six weeks after a one-week audit. Smaller projects, like a single enrichment and scoring table or an inbound routing workflow, can ship in days.
Do I own the systems OneGTM builds?
Yes. Everything is built in your accounts and documented, so your team keeps the tables, workflows, and code after the engagement ends.
What tools does OneGTM build with?
Clay for enrichment and signals, n8n for automation, HubSpot or Salesforce as the CRM, Instantly, Smartlead, or Lemlist for email, HeyReach for LinkedIn, and Claude Code or Cursor when custom software is the faster path.
How much do GTM engineering services cost?
OneGTM works on fixed project fees, monthly retainers, or advisory terms depending on how much you want built versus guided. Pricing depends on scope, and a short call is the quickest way to get a number.
