Case study · AI product
From model demo
to launched product.
Lumen had a genuinely good demo and nothing around it: no product, no brand, no way to ship. Eight weeks later it launched publicly, and the launch held.
The challenge
A great demo
is not a product
The founding team had built something impressive in a notebook: a model pipeline that did its one thing well. Everything a stranger touches was missing. There was no interface, no account system, no brand, no answer to the question of what happens when the model is wrong.
Launch pressure was real. Two better funded competitors were circling the same space, and every month spent polishing in private was a month of lead evaporating. The brief was blunt: make this real, and make it hold up in public.
Our approach
Evals first,
then everything visible
The quality bar, written down
Before any interface, an eval suite that defined good. Every change afterwards had to beat it, which is why launch week was quiet.
Brand and product as one system
Identity, site and interface designed together, so what launched looked like one finished company, not a dressed up demo.
A thin slice in production
A private beta with real users behind a guardrail, weeks before launch. The embarrassing lessons happened in front of fifty people, not ten thousand.
Launch as an engineering event
Rate limits, monitoring, cost ceilings and a rollback plan. The waitlist converted without the site or the model falling over.
