Lean Startup didn’t fix anything. It might be the reason founders keep failing.

We’ve spent 25 years chanting “MVP” like a religion.

And the failure rate hasn’t moved an inch.

So, either Lean Startup is wrong… or founders are doing it painfully wrong.

Most people won’t like that framing. Good. It’s true.

Founders still build before they understand demand. Still chase “product–market fit” like it’s sequential. Still treat “customer discovery” as talking to five polite friends. Still ship broken prototypes and call it learning.

This isn’t Lean. It’s theater.

And the data hasn’t budged. 42 percent still fail because there’s no market need. Translation: we’re building before marketing. Again.

Steve Blank warned us twenty years ago. “Get out of the building.” But somehow the industry mutated that into “Google some stats.”

MVP was meant to prove demand. Instead, it became a hall pass to build too much, too soon.

If you can’t sell it, your MVP isn’t minimum. And it sure isn’t viable.

Lean Startup didn’t fail us. We failed it. We turned a scientific method into a checklist.

That’s why accelerators produce pitch decks instead of businesses. Why coworking spaces are full of prototypes and empty wallets. Why founders confuse invention with entrepreneurship.

It’s not product–market fit. It’s market–product fit. Always.

Demand first. Product later.

If that order makes you uncomfortable, it should. It changes everything.
