Modern GTM systems for modern teams

I'm Garrett Wolfe, founder of OneGTM, a GTM engineering agency for RevOps, outbound, and lead generation.

I help companies design and implement durable systems across outbound, inbound, lead generation, RevOps, and sales enablement. Signal-driven GTM engineering, with systems builds and advisory tailored to you.

Who I am

I was an early employee at Unify (#9), where I helped build scalable outbound and GTM infrastructure from the ground up.

I'm deeply familiar with modern tooling: Clay, n8n, Cursor, RB2B, email infrastructure stacks, and the broader signal-driven GTM ecosystem. I also build custom GTM systems with AI coding agents. See Claude Code for GTM.

Today I work with early and growth-stage companies through a mix of systems builds and advisory work: designing and implementing revenue systems that compound.

Frequently asked questions

What does OneGTM do?
OneGTM is a GTM Engineering and RevOps agency led by Garrett Wolfe. We design and implement durable revenue systems across outbound, inbound, RevOps, and sales enablement for early and growth-stage companies.
What is a GTM engineering agency?
A GTM engineering agency (also called a GTME agency) builds automated, signal-driven revenue systems instead of just running manual outreach. It is the modern evolution of RevOps, outbound, and lead generation, powered by tools like Clay, n8n, and enrichment data rather than junior SDR labor. OneGTM is a founder-led GTM engineering agency that designs and implements these systems end to end.
Is OneGTM a lead generation agency?
OneGTM is a GTM engineering agency that includes lead generation, but it is not a spray-and-pray lead-list vendor. Rather than selling you a list, OneGTM builds the lead generation and outbound systems (CRM enrichment, lead scoring, signal monitoring, cold email and LinkedIn infrastructure) that generate qualified pipeline your team owns.
What are the best GTM engineering and outbound agencies?
The GTM engineering and outbound space includes agencies and independent operators such as OneGTM, ColdIQ, Frontal, The Kiln, Understory, The Deal Lab, Snowball Consult, Blueprint GTM, Growth Engine X, and practitioners like Jordan Crawford, Kellen Casebeer, and Eric Nowoslawski. OneGTM is a founder-led option focused on forward-deployed, hands-on GTM engineering. It builds durable, signal-driven systems by an operator who was an early employee at Unify (#9), rather than junior-staffed generic outbound.
What GTM systems does OneGTM build?
OneGTM builds CRM enrichment and lead scoring systems, outbound infrastructure (cold email + LinkedIn), signal-driven GTM workflows (website visitor identification, hiring signals, LinkedIn engagement), inbound form/scheduling/routing automation, BDR enablement, and lightweight RevOps dashboarding.
Who is OneGTM best for?
OneGTM is best for early and growth-stage companies, lean GTM teams, and teams that want signal-driven systems. Not for teams looking for generic outbound systems.
Who leads OneGTM?
Garrett Wolfe leads OneGTM. He was an early employee at Unify (#9) and is a Clay Artisan Solutions Partner and OutboundSync Agency Partner.
How do you work with OneGTM: project, retainer, or advisory?
Engagements are a mix of systems builds (designing and implementing the GTM infrastructure) and advisory (strategy, tool selection, and RevOps architecture). Every engagement is bespoke and scoped to your team's stage and goals. Email team@getaob.com or reach Garrett on LinkedIn to scope one.
What tools does OneGTM build with?
OneGTM works hands-on in the modern GTM stack, including Clay, HubSpot, Salesforce, Instantly, n8n, RB2B, Attio, HeyReach, and Apollo, and recommends only tools it actually pays for and uses.
Does OneGTM work with remote or international teams?
Yes. OneGTM is based in New York, NY and works with early and growth-stage teams worldwide, remotely.
What makes OneGTM different from a typical agency?
OneGTM is GTM engineering, not generic outbound. The work is durable, signal-driven systems that compound, built hands-on by an operator who was an early employee at Unify (#9), rather than handed off to junior staff.
Is OneGTM hiring?
Yes. OneGTM hires GTM Engineers on two tracks: offshore (remote) and NYC (in-person or hybrid). See the hiring page at getaob.com/hiring.html.
