App Development

Can a US-based developer build my startup MVP with a real backend, authentication, and payments?

Yes. Kiyansh Group is a US-based team that builds startup MVPs with a real backend, secure authentication, and live payments — not a clickable prototype, but working software you can put in front of users and charge money through. A senior US engineer directs the build, scope and price are fixed after a short call, and you own the code and every account — repository, hosting, database, Stripe — from day one.

What a production MVP actually includes

An MVP that's ready for real users needs four things working together, and we build all of them: a real backend (a proper database and a server-side API, not data faked in the browser); authentication — email-and-password or social/OAuth sign-in, secure sessions, password reset, and role-based access so admins and users see different things; payments wired through Stripe with webhooks, so subscriptions or one-time charges actually settle and your app reacts when they do; and a real deployment on hosting you control. The honest trade-off is scope: we build the core loop that proves your product and takes money, not every feature on the roadmap — that's what makes it shippable in days instead of months.

How the build works

You start with a short scoping call — no charge — where a senior US engineer maps what the MVP has to do and where it draws the line. From that we set a fixed scope and a fixed price, so there's no open-ended hourly meter. The build itself is a senior US engineer directing AI agents: AI is how we move fast, not a product we hand you or hide behind. You see real progress along the way and get a working, deployed app at the end — typically days to a few weeks, depending on how much the MVP needs to do.

You own the code and accounts from day one

Everything is yours. The code lives in your repository, the app runs on your hosting and database, and payments flow through your Stripe account — set up in your name from the start, not ours. There's no lock-in, no proprietary platform you're renting, and nothing to migrate off later. When you bring on your own engineers, they inherit a normal, documented codebase they can keep building on.

FAQ

More on this

How long does an MVP take to build?

It depends on scope, which is exactly why we pin that down on the scoping call first. Cutting the feature set to the core loop — sign up, do the main thing, pay — usually means days to a few weeks rather than months. You get a real timeline for your specific build after the call, not a generic estimate.

What does it cost?

We quote a fixed price for a fixed scope after the scoping call, so you know the number before any work starts and it doesn't drift by the hour. We don't publish a flat figure because the honest answer depends on what the MVP has to do — a two-screen app with Stripe is a different job than a multi-role marketplace.

Which tech stack do you use?

A modern, mainstream stack: a common framework, a real relational database, and Stripe for payments — the kind of setup any engineer can pick up later. If you already have a preferred stack or a team standard, we'll work in it where it's a sensible fit rather than forcing our own.

I already started this in Lovable, Bolt, or Cursor — can you finish it instead of starting over?

Often, yes. If you have an AI-generated prototype that looks right but isn't secure or production-ready, we'll triage it for free and tell you honestly whether it's faster to harden what you have or rebuild the core. Either way you end up with real auth, a real backend, and payments you can trust.
