Stealth Startup 0 is an applied research lab shipping the infrastructure that will power the next decade of software — before anyone knows we built it.
We operate in stealth not because we're hiding — but because deep work needs quiet. Our team ships primitives the rest of the industry hasn't named yet.
When we surface, it's with finished things. No press tours, no leaked decks, no half-products. Just infrastructure that suddenly seems obvious.
The two operations consuming all of our cycles right now. Everything else is on hold until these ship.
One terse email when something ships. No marketing, no founder essays, no growth funnel. Unsubscribe is one keystroke.
We hire only when someone changes the trajectory of a stream. No listings, no coding interviews, no panels. Two conversations and a one-week paid trial.
Send a paragraph and a link. Repos, papers, prototypes, shipped products. We read everything.
