Flutter MVP Development for Startups

A tightly scoped MVP — one core flow, authentication, a Firebase backend and both platforms — is typically a matter of weeks rather than months. What stretches it is scope creep during the build and waiting on decisions or content from your side. I give a stage-by-stage estimate after the scope workshop, because an estimate made before that conversation is a guess.

Anything that doesn't change the answer to your core question. In practice that usually means: profile editing, settings screens, onboarding carousels, social login beyond one provider, in-app messaging, notifications that aren't essential to the loop, and any admin interface that a spreadsheet could do for your first fifty users. We go through your feature list together in the scope call and I'll argue for cutting more than you expect.

For most first versions, FlutterFlow. If your MVP is built from forms, lists, authentication and Firestore — and the majority are — the low-code route gets real users in front of it sooner and for less, which is the entire point of an MVP. Custom app development, meaning hand-written Flutter, earns its cost when the product depends on bespoke animation, complex offline sync, or something the builder genuinely cannot express. I build both and will recommend the cheaper one when it fits, even though it is the smaller project for me.

Yes, and most MVP enquiries are pre-funding. It mainly changes how we scope: a fixed budget means we work backwards from what you can spend to what's buildable, rather than designing the ideal product and discovering the cost afterwards. Tell me the number early and you'll get a far more useful conversation.

No. I work on paid engagements only. It isn't a judgement on your idea — equity-for-build arrangements tend to misalign incentives on exactly the decisions that matter in an MVP, like cutting scope, and they leave both sides worse off when priorities diverge. A smaller paid scope is almost always better for you than a larger equity one.

It can be built so it doesn't have to be thrown away, which is what I default to: typed models, business logic out of widgets, shared components, and a Firestore schema designed around read patterns rather than screens. That said, an MVP that succeeds will need work before it serves a hundred thousand users, and that's normal. The goal is that v2 is an extension rather than a rewrite.

Yes, both, from the first commit. The repository is on your GitHub or GitLab account wherever possible and the Firebase project is in your account, not mine. That matters more than founders usually realise — it means you can hand the project to anyone, or take it in-house, without needing anything from me.

I can make sure the build supports one: a stable demo path, seeded data that makes the flows look real, and a TestFlight or internal testing link investors can install rather than watch over your shoulder. I won't build a demo that fakes functionality the product doesn't have — that tends to surface at exactly the wrong moment.
