MVP Development

An MVP that survives product-market fit

Founders don't need a no-code prototype they'll throw away. They need a real product, scoped ruthlessly, shipped in weeks, on a stack that scales. We build the version you keep — the one that doesn't need a rewrite at Series A.

Built for · 01

You're probably reading this if…

  • You're a pre-seed or seed founder who needs a working product in front of users this quarter, not a deck of mockups.
  • You're a non-technical founder and need a senior team that owns the architecture so you're not betting the company on a freelancer who ghosts.
  • You're funded and racing an investor deadline or a launch window, and you can't afford to discover the build is unscalable in month three.
  • You got burned by a cheap agency, you're sitting on a codebase nobody can extend, and you need it rebuilt right the first time.

The breakage we see most

These are the patterns that show up on first calls. If you're seeing 1+ of these, an architecture audit will save you weeks.

Scope that quietly tripled before launch

The 'MVP' grew to 40 screens, an admin panel, three roles, and a billing system — before a single user touched it. We cut the build to the one loop that proves the thesis and ship that in weeks.

A no-code prototype with nowhere to go

Bubble or Airtable got you a demo, then hit a wall — no real auth, no integrations, no way to handle your first 1,000 paying users. We rebuild on a stack that doesn't dead-end the moment traction shows up.

The agency that disappeared after the deposit

Slow replies, a junior offshore team, code you can't read, and a repo you may not even own. We run Friday demos, commit to a shared repo from week one, and you own everything.

An MVP with no path to scale

It works for the demo, then falls over at 50 concurrent users because everything's synchronous and there's one un-indexed query carrying the whole app. We build it to handle your seed-round traction from day one.

A throwaway you have to throw away

Investors want the next milestone, but the codebase is a prototype held together with hacks, so the real build starts from zero — burning your runway twice. We build the version you extend, not the one you discard.

No senior in the room making the calls

The hard decisions — data model, auth, what to defer — got made by whoever was cheapest, and now they're load-bearing mistakes. Every TantraDev build is led by engineers with 7+ years who've shipped this before.

What we ship · 03

The exact deliverables on a typical engagement

1

Ruthless scoping & build plan

We pressure-test the idea down to the single core loop worth proving, kill everything that can wait, and hand you a fixed scope, timeline, and price before we write code.

2

The core product, end to end

Real authentication, the primary user workflow, a clean data model, and the one or two integrations the thesis actually depends on — built to production standard, not demo standard.

3

A stack that scales past the MVP

TypeScript, Next.js, a proper relational database, and managed cloud infra — chosen so the same codebase carries you from first user to Series A without a rewrite.

4

Payments & onboarding when you need revenue

Stripe or Razorpay billing, subscription logic, and a signup-to-value flow built to convert — so you can charge real money and measure willingness to pay, not just sign-ups.

5

Analytics & instrumentation from day one

Event tracking and the funnels that tell you whether you've found fit, wired in from launch — so your investor update is backed by data, not vibes.

6

Deploy, CI/CD, and the keys to everything

Live on your own cloud account with automated deploys, monitoring, and error tracking. You own the repo, the infra, and the IP — handover is part of the deal, not an upsell.

7

A clear runway past launch

After you ship, you can keep us on to iterate on real feedback, or take the codebase fully in-house — it's documented and built for another team to extend either way.
