GTM Operator

I build revenue systems and the teams to run them.

About

I'm a GTM operator with a track record of building revenue systems from scratch.

I spent the last three and a half years at Chapter, a Medicare guidance startup, where I built the outbound motion, BDR team, and RevOps infrastructure that scaled partnerships across multiple verticals. During that time, Chapter raised from series B to series D and grew 10x.

Before that I was a financial advisor at a small RIA in Boston.

I've spent the past nine months building independently — GTM pipeline systems, AI revops workflows, advisory work. A few volcanoes too.

In my free time I enjoy playing tennis, guitar, writing, philosophy, neuroscience, and traveling (usually somewhere with no cell service).
