§ Case study

RoostGrid — from idea to first paying user in 11 days

A scheduling tool for small studios. We took it from a sketch on a napkin to a paying user in less time than most teams spend on a kickoff workshop.

What the client needed

Maria runs a small photo studio and her three assistants were spending an hour a day juggling a shared calendar in WhatsApp. She had a clear mental model but no time to build it.

What we built

A single-page web app that handles bookings, conflict detection, and a per-assistant view. Vibe-coded with Next.js + Postgres, deployed on her own domain.

Outcome

First paying user signed up on day 11. Three months later they hit 40 active studios with zero post-launch dev time from us beyond a single "Grow" retainer week.

§Built with the AI tools we use every day. Plain stack, no lock-in.
