The 90-day SaaS MVP that actually gets used

By the Imustech product team · Updated November 2025

Every founder we meet has heard "just ship the MVP" and every one of them still ships too much. Here's the compressed 90-day model we use — the one that yields a version customers pay for, not a demo that dies in a spreadsheet.

Weeks 1–2: The narrowest possible slice.

Pick one job-to-be-done. Not one persona, not one segment — one job. Everything you scope must directly answer: "Does the person doing this job save an hour or make a rupee?" Anything else is version two.

If your MVP has "settings" you probably scoped a v2.

Weeks 3–5: The starter kit, on rails.

We build multi-tenancy, auth, billing and admin from day one — but with rails so tight that they take three days, not three weeks. This is where most agencies bleed money. We don't.

Weeks 6–9: The one flow that matters.

Now, and only now, we build the actual product surface. One flow. One "aha". No settings, no admin nesting, no branded onboarding videos. If a user can't reach the "aha" in ninety seconds, we shorten the path.

Weeks 10–12: Ten paying design partners.

Not fifty. Not a launch on Product Hunt. Ten paying design partners who are willing to sit on Zoom while you watch them use the product. That's the goal of a 90-day MVP — a small, real customer base you can iterate with.

The rules we follow, without exception

• No settings. Every "should we make this configurable?" is a "no".
• No integrations in v1. One export button; that's it.
• No mobile app. Responsive web only.
• No marketing site more elaborate than the product.
• Ship on Friday. Every Friday. From week one.

What ships on day 90

A product with one flow, ten paying customers, and a roadmap informed by watching those customers use it. That's what we've shipped for founders in fintech, healthtech, developer tools and vertical SaaS. It works because it forces the hard conversations to happen while the code is still small.
