About

Founder and GTM Systems Builder

I build revenue systems for B2B teams: the data foundation, the enrichment, the outbound campaigns, the CRM plumbing, wired together so it keeps producing after I leave.

I've spent 12+ years in B2B sales and bootstrapped three companies to $5M+ combined revenue. At SmartBound, the B2B outbound agency I co-founded, I built the GTM engine to help take us from zero to $300k+ in year one. One automated campaign there closed $70k+ over twelve months.

I graduated from Clay's third cohort in 2024, the certification program for the tool at the center of most of my builds and have served 20+ B2B clients with outbound builds and GTM systems.
