How do I hire one vendor for mobile, web and backend?

Most digital products need three surfaces at once: a mobile app, a web app, and the backend and APIs that power both. When you hire three separate vendors, the seams between them become your problem — mismatched data models, duplicated business logic, and endless "that is the other team's bug" conversations. A single full-stack vendor designs the backend once and lets the mobile and web clients share it, so the whole product stays consistent.

Ubikon runs mobile, web, and backend as one team on a single fixed-price contract. The backend (Node.js or Python/FastAPI with PostgreSQL or MongoDB) is built as the shared source of truth, the web front end uses Next.js, and the mobile app uses React Native or Flutter against the same APIs. One project manager, one delivery plan, and one point of accountability replace three vendors and three invoices.

A common fear with a single vendor is lock-in — if one company holds everything, can you ever leave? Ubikon removes that risk structurally: an IP-assignment agreement is signed before day one, so you own 100% of the source code and intellectual property across all three layers from the start. There is no proprietary black box you cannot take with you.

Because the stack is mainstream and well-documented (React Native, Flutter, Next.js, Node.js, PostgreSQL, MongoDB), any competent team can pick it up later. That combination — one accountable vendor plus full ownership and zero lock-in — gives you the coordination benefits of a single team without the dependency downside.
