Blueprint started as a hackathon build for STEMist Hacks IV, and the problem it's solving is one I've run into myself: it's hard to find the right people to build something with. Blueprint is a social platform for engineers and builders, you post a project idea, an AI breaks it down into roles, tasks, and a brief, and it matches you with teammates against the roles that are actually open.
Once a team forms, Blueprint spins up a shared workspace for it automatically, chat and a task board, so the team can start working instead of spending the first few days just organizing. It's built on Firebase, and the first thing I shipped was sign-in with Google and GitHub, since that's the door everything else walks through.
The name changed along the way. It started as Beacon, then briefly Circuit, before settling on Blueprint, which fit better: the app's whole job is turning a rough idea into a plan other people can build from.
