Most startups don’t fail because they can’t build. They fail because they build the wrong thing.
I’ve spent 15 years developing a systematic way to fix that.
Hi, I’m Ash Maurya
I’m the author of Running Lean and Scaling Lean, and the creator of Lean Canvas—a one-page business model used by over 1 million founders worldwide.
For the past 15 years, I’ve been obsessed with one question: how do you systematically test whether a startup idea will work—before you build it?
I’ve taught the Continuous Innovation framework to thousands of founders, coaches, and accelerators. The pattern is always the same: the founders who win aren’t the fastest builders. They’re the fastest learners.
LEANSpark puts that methodology into a tool that remembers your business model, guides you through validation, and gives you specific next steps—not generic advice.
Why I Built LEANSpark
The Problem
Founders are shipping faster than ever—and failing at the same rate. Speed doesn’t help if you’re building the wrong thing.
Most tools help you build. Nothing helps you figure out what’s worth building. That’s the gap.
The Solution
LEANSpark guides you through 90-day validation cycles built on the Continuous Innovation framework.
Map your assumptions on a Lean Canvas. Run a 7-dimension assessment. Design experiments. Test your riskiest assumption first. Make data-driven decisions. All with persistent context specific to YOUR business.
The Proof
I used LEANSpark to validate LEANSpark. Built in public through 6 "Over-the-Shoulder" episodes on YouTube. Same stress-testing. Same 90-day cycles. Same methodology.
Result: 0 to 307 customers. $115K revenue. Product roadmap clarified through systematic validation.
