B2B SaaS MVP shipped in 7 days
Stealth SaaS founder

The challenge
A solo founder had validated demand through waitlist signups but needed a working product (auth, billing, and core workflow) before a YC application deadline in two weeks.
The solution
We ran a 7-day MVP sprint: scoped to one core workflow, wired Clerk auth, Stripe checkout, and a Postgres-backed dashboard. Daily async updates and a live Vercel preview kept the founder in the loop.
“Koustav shipped what would have taken me two months in a week. I talked to the person building it every day. No handoffs, no surprises.”
