About David

Operator. Builder. Documentarian.

I build these systems inside my own companies first. Timechain is the flagship — a real operating business being rebuilt to run on agents, documented in public.

The philosophy comes from the Bitcoin world: if you believe in owning your money, you should own your tools and intelligence too.

No agency layers. If we work together, you work with me.
