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.

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. and much more, totally bespoke to your needs ## Related - [GTM engineering agency](https://getaob.com/gtm-engineering-agency): Founder-led outbound, signal, CRM, and AI systems for seed to Series C teams. - [AI SDR alternatives](https://getaob.com/ai-sdr-alternatives): Custom signal-driven systems to use instead of a packaged AI SDR, with the same published proof. - [All GTM tool guides](https://getaob.com/gtm-tools): Every tool category we cover, from cold email and LinkedIn to signals and dialers. - [GTM engineering guide](https://getaob.com/gtm-engineering): What GTM engineering is, how it differs from RevOps, the stack, five core workflows, and how to start. - [Buying signals guide](https://getaob.com/buying-signals): The 15 B2B buying signals worth tracking, how to detect each one, and how to turn a signal into outreach. - [How a OneGTM engagement works](https://getaob.com/how-i-work): The end-to-end build from account list to booked meeting, the 12 work modules, and who owns what. - [GTM playbook](https://getaob.com/gtm-playbook): A practical go-to-market checklist for B2B startups, from ICP and signals to outbound, routing, and measurement. - [OneGTM case studies](https://getaob.com/case-studies): Customer results from GTM engineering engagements, and how each one was measured. - [Coastal Recruiting case study](https://getaob.com/coastal-recruiting-case-study): How a recruiting firm grew recruiter-accepted candidate intros 4.7x in four months. - [Antimetal case study](https://getaob.com/antimetal-case-study): 17 Automated Outbound deals and $2.57M in pipeline from the signal system OneGTM built and handed over. - [Green Dock Partners case study](https://getaob.com/green-dock-case-study): A tracker that watches public closure news and sends an industrial real estate investor a daily digest. - [Free GTM scorecard](https://getaob.com/gtm-scorecard): Twelve questions that grade your go-to-market engine across six areas, with fixes for the weakest ones. - [Outbound cost calculator](https://getaob.com/calculator): Year-one fully loaded cost of hiring BDRs or a GTM engineer, with sourced defaults for salary, benefits, ramp, and attrition. - [What is a GTM engineer?](https://getaob.com/gtm-engineer): The role, salary ranges, skills, and tools, from the State of GTME report. - [Best GTM engineering agencies](https://getaob.com/gtm-engineering-agencies): The full landscape of GTM engineering, RevOps, and Clay agencies. - [Clay pricing explained](https://getaob.com/clay-pricing): Plans, Actions, Data Credits, and how to cut your Clay bill. - [AI transformation agency](https://getaob.com/ai-transformation): Readiness assessment, a 90-day roadmap, builds, and training. ## Work with OneGTM Tell me what you're building.
