The full answer
Investors respond to something they can touch. A demo that walks through the core user journey, with real-looking data and the key moments of value, communicates the product far better than a deck. It also forces the founding team to decide what the product actually is before raising.
Creuto scopes the demo around the story you need to tell in the meeting: which users, which three or four screens, which interactions must work and which can be simulated. The design is finished to a standard that looks like a shipped product, because that is what investors compare it against.
Where it makes sense, the demo is built on the real stack, React, Next.js and TypeScript on web or Flutter and React Native on mobile, so the code is not thrown away. After funding, the same team continues into MVP development, which typically takes 4 to 8 weeks for a focused first release.
Demos are built on a fixed scope with a clear deadline, usually your pitch date, and the proposal sets out exactly what will work on the day. You own the code and design files. Tell Creuto your timeline on a discovery call and the team will say honestly what can be ready.
