Last week, we broke down the MVP crisis: why 90% of startups fail, why the MVP phase bleeds founders dry, and why speed to market is the variable that separates survivors from the startup graveyard. If you missed it, go read that first.

The short version: MVPs take too long, cost too much, and most founders confuse them with prototypes or landing pages. The fix isn’t “just build faster.” Speed without structure produces chaos.

This week, we’re going deeper into the structure part. Specifically, the document that should exist before a single line of code gets written — and almost never does.

We’re talking about the PRD. The Product Requirements Document.

If that sounds boring, good. It should sound boring. The most important documents in any company are the ones nobody wants to write. And the PRD is the one that, when skipped, turns your MVP from a learning machine into a money pit.

If you are comparing an AI app builder with a no code AI app builder, the wrong way to evaluate them is by asking only one question: "Can this build my app fast?"

Speed matters, but it is not the real decision.

The real decision is whether the tool or partner helps you ship the first version without locking you into a weak technical foundation.

Many teams think the hard part is writing the PRD.

In practice, the next handoff is where the real trouble starts.

The PRD explains what the product should do. The technical scope explains how the team is going to deliver it.

The easiest time to avoid vendor lock-in is before you sign anything.

The hardest time is after the first version is live, the product is working, and the team realizes the original route is harder to extend than expected.

One of the fastest ways to lose clarity after writing a PRD is to dump the whole document into Jira and hope the team turns it into good tickets later.

That usually creates one of two problems:

• the tickets are too vague to estimate
• the tickets are so detailed that nobody can see the release clearly anymore

Linear works best when the scope is already clear.

If the PRD is still vague, moving everything into Linear too early just gives you a cleaner-looking backlog with the same confusion inside it.

Most founders do not start with a PRD. They start with a rough product idea, a few notes, and a list of features that keeps changing.

That is normal. The problem starts when the team tries to build from that raw input.

An AI PRD generator is useful only if it helps you create a document that engineering, design, and stakeholders can actually use.

Founders often say they want an investor-ready MVP when what they really mean is one of two things:

• they need a product that demonstrates a credible first user journey
• they need a build that looks serious enough to support fundraising conversations

Neither goal requires a bloated first release.

Founders usually think about source code ownership late.

That is understandable. Early on, speed dominates every decision. But once the MVP is live, ownership becomes one of the most important commercial and technical questions in the business.

Ninety percent of startups fail. You’ve heard that number so many times it’s lost its weight. But sit with it for a second. Nine out of ten. Not nine out of ten bad ideas. Nine out of ten funded, staffed, motivated teams with real money, real talent, and real conviction.

The question isn’t whether startups fail. The question is why the ones with promising ideas still fail. And for a startling number of them, the answer traces back to a single phase: the MVP.

The minimum viable product was supposed to be the antidote to wasted effort. Build small, learn fast, iterate. Eric Ries popularized the concept in The Lean Startup, and it became gospel. Every accelerator teaches it. Every pitch deck references it. Every founder swears by it.

And yet, MVP development remains the phase where most startups bleed out.

This is the crisis nobody talks about honestly. Not the “startups are hard” platitude. The specific, structural reasons why the MVP phase — the one designed to reduce risk — has become the phase that generates the most risk.
