Brett Chereskin
I’m the COO of dub, a venture-backed consumer fintech. I run operations at the edge of what AI can do — shipping internal tools that replace entire functions — and angel invest in the founders doing the same. Earlier: twelve years in the Army, West Point ’06.
Three lanes, concurrently.
- 01Operating. COO of dub, a venture-backed consumer fintech. Ops, finance, HR and G&A — run lean with AI tooling I build in-house.
- 02Practicing. I ship real AI systems in production at a regulated company. I write about what works, what breaks, and what I’ve quietly retired.
- 03Investing. Angel investor and LP. I back operators shipping with AI. Advisory work on ops, GTM, and AI adoption inside scaling companies.
