AI-Powered GTM Systems
I build automated, AI-driven marketing infrastructure that scales output without scaling headcount.
About
I bring 15+ years building and running marketing at B2B tech startups. My expertise is in sales-led, B2B, technical products with a developer audience. I've done this at every stage: from pre-PMF to public companies.
I use AI and lean teams to build full-stack marketing functions including PMM, brand, demand gen, content, comms, analytics, and more. I believe in delivering results by providing context and expecting accountability.
My approach is to build tech-driven GTM systems that let small teams punch well above their weight. Automation, intelligence, and operational rigor that allows humans to focus on the work that actually matters.

How I Work
Approach & Skills
Full-Stack Marketing
Product marketing, brand, demand gen, content, and more. I own the whole function, not just a lane.
Technical Fluency
Confident with APIs, SDKs, MCPs, and developer audiences. More than a marketer, not quite an engineer.
GTM Strategy
ICP, positioning, narrative, launch, sales enablement and more from 0 → 1 and beyond.
Lean Team Leadership
I like to hire, develop, and run lean, high-output teams; do more with less by design.
Economics-Trained Thinking
I bring analytical rigor and systems thinking to every marketing problem.
