Enterprise-grade Revenue Operations & GTM engineering for B2B teams that want systems built to scale - not another tool setup that breaks at volume.

With a 15-year software-architecture background, I design the full go-to-market motion as a system - platform infrastructure, enrichment, automation, CRM, and custom AI agents - the way a senior engineer builds production software: rigorous, documented, and yours to own.

What sets this apart is range delivered with senior rigor. FuelGTM brings what a multi-person GTM team usually splits across specialists - GTM architecture, Clay engineering, CRM development, and custom software - and I now lead a small, highly skilled team that extends that range without diluting it. One accountable architect on point, a vetted team behind the build, with AI augmentation (Cursor, Claude Code, MCP servers) built into the work so we ship faster and solve problems configuration alone can't. One partner owns both your CRM and your Clay

I'm a Clay Advanced Artisan (top tier of the partner program), a Salesforce Certified Developer, and HubSpot certified - a combination few hold together. Trusted by 25+ B2B companies across 10 countries - Newsweek, Veryon, Cryptio, Kumo, Moxie, Rollstack, YunoJuno, SlashExperts, and OurFamilyWizard among them - to build the systems their revenue runs on, across SaaS, Healthcare, Recruiting, and Security.
