MVPs scoped to learn, not just to launch.

We ship MVPs in 4 weeks. Fixed scope, fixed price, real codebase, production-ready. The kind of MVP you can put in front of a customer on day 30.

The problem

Why most MVPs aren’t actually minimum or viable.

Either the agency over-scopes — twelve flows, fifteen weeks, the launch slips, and you’ve built something nobody asked for. Or they under-scope — three screens, no auth, nothing learnable, and you’ve spent $10K on a clickable prototype. Both miss the point. An MVP exists to test a hypothesis with real users. We scope it to the hypothesis, ship it in weeks, and design it to be expanded — not rebuilt — when the data comes in.

What we ship

Four shapes, one engineering team.

01

SaaS MVPs

Web MVPs with auth, one or two core flows, real Stripe billing if needed. Production from day one.

See case study
02

AI-native MVPs

MVPs where the AI is the product. RAG, agents, evals — the AI version of MVP.

03

Mobile MVPs

iOS or Android (or both) MVPs via React Native. TestFlight in 4 weeks.

04

B2B platform MVPs

Multi-tenant, role-aware, dashboard-style MVPs for B2B products.

Why Zaibex

Side-by-side with a typical agency.

We don’t outbid the cheap shops, and we don’t pretend to be McKinsey. Here’s where the real practical difference lives.

The stack

The exact tools and why we chose them.

No mystery stack, no platform lock-in. You see what we use, you read why, and you own the keys on day one.

01 · Frontend
Next.js 16 · TypeScript

Fast to build, production-ready, AI-ready by default.

02 · Database
Postgres · Drizzle

Real database from day one — no NoSQL improvisation that has to be rebuilt later.

03 · Auth
Clerk · Auth.js

Auth that scales — multi-tenant, SSO-ready when you need it.

04 · Billing
Stripe

Subscriptions, metering, the only billing stack worth using.

05 · Hosting
Vercel · Railway

Zero-config deployment, scales when you do.

06 · AI hooks
Claude · OpenAI

AI-ready from day one — add features when you want them.

The process

Discover · Architect · Build · Ship.

Four stages, named timelines, named deliverables. No open-ended discovery. No moving goalposts.

01·3 days

Discover

We narrow scope ruthlessly. What’s the hypothesis you’re testing? Three flows max.

  • Hypothesis
  • Scoped feature list
  • Success criteria
02·3 days

Architect

Schemas, routes, deployment plan — written down before code starts.

  • Data model
  • Routes spec
  • Deployment plan
03·2–4 weeks

Build

Weekly demos. We ship to staging at the end of week 1, every week after.

  • Working MVP
  • Test coverage on critical paths
  • Production-ready build
04·1 day

Ship

Production launch with onboarding. 30 days of post-launch iteration.

  • Production cutover
  • Analytics + funnel tracking
  • 30-day post-launch iteration
In production

Real numbers, named client.

Multi-currency B2B fintech MVP

The problem

A B2B fintech needed to test a multi-currency platform with real customers before building the full product. Most agencies quoted 12+ weeks and $50K+.

Our approach

We scoped to two flows, built with auth + multi-currency from day one, shipped in 6 weeks for a fraction of the alternative budget.

The outcome

50% AUM growth post-launch. Platform validated with real customers, expanded into a full product without a rewrite.

Pricing & timeline

Fixed price. Fixed scope. Public ranges.

We don’t hide pricing behind a sales call. Pick the tier that matches your stage. The discovery call confirms scope, not budget.

Honest answers

The questions we actually hear on calls.

Is 4 weeks really enough for an MVP?

For a hypothesis-focused MVP — yes. For a "whole product" MVP — no, and that’s not an MVP. We scope to what you can actually validate in 4 weeks. The rest is v2.

What if my MVP needs more than 4 weeks?

Then it’s Custom. 6–10 weeks for larger scope, still fixed-price. We tell you upfront whether your MVP fits the 4-week tier.

Will the MVP be production-ready or throwaway?

Production-ready. Real codebase, real auth, real database, deployed to your cloud. No clickable Figma. If you want a prototype to show investors, that’s a different (cheaper) engagement.

Can we extend the MVP into a full product?

Yes — that’s the point. We build with the assumption that you’ll keep going. The code is structured to expand, not rewrite.

Why fixed-price and not hourly?

Because hourly punishes you for slow agencies and rewards them for slow work. Fixed-price aligns incentives — we ship when we ship, you pay what we agreed.

What about ongoing development after launch?

Optional retainer. Most clients add features for 3–6 months post-MVP. Or take the code and hire in-house. Your call.

Ready when you are

Most MVPs fail by trying to be everything. The good ones test one clear hypothesis with one clear scope, ship in weeks, and earn the right to be expanded. We build the good kind — and we tell you upfront if your idea fits the 4-week tier or doesn’t.
