Sound familiar?

“I have an idea but no clue what to do first.”

“ChatGPT gives generic advice. I need someone who knows MY business.”

“Every session I start over. There’s no continuity.”

The stress test, across 7 dimensions

For organizations

Not just for solo founders.
LEANSpark scales to whole cohorts.

Schools, accelerators, and innovation programs run their entire cohort on the same methodology — with a dashboard to coach every founder, not just the loudest few.

Schools & universities

The cost of a textbook, the depth of a co-founder — every student gets a 24/7 AI co-founder trained on Ash Maurya's frameworks.

Accelerators & incubators

Coach every founder, not just the loudest twenty percent — screen applicants, run validation sprints, and see cohort progress in one dashboard.

From the founders

Validated before a line of code shipped.

LeanSpark is a game changer. It makes busines model development doable as an ongoing practice.

I used LeanSpark to demo, sell, and build ArtistsZone, The Beyond The Portfolio Course, and the ArtistsZone Community. We signed our first school and have started teaching the course to our first cohort of students.

Edward Phelps CEO, ArtistsZone
LEANSpark guided development of my business model and stress-tested it like Ash would and the resulting canvas was 10x better than I'd ever done on my own.

Before LEANSpark, I tried to build my business using LeanCanvas and other lean methodologies. But I didn't have anyone or anything really pushing to gather enough data or sharpen the model to where I needed it to be. Not only did LEANSpark guide me through a proper LeanCanvas development process, but it stress tested the problem, the timing, the value proposition, the defensibility, and every other key dimension of the model. Plus LEANSpark provided helpful advice on how to solve the problems it surfaced.

Stephen Kuenzli Founder, CEO, k9 Security
LEANspark has been incredibly valuable for validating ideas, refining business models, and creating clarity fast. I’ve even referred clients to it.

Before LEANspark, I was trying to shape the offer, positioning, and validation process mostly from instinct. LEANspark helped me pressure-test the model, tighten the messaging, and identify what actually mattered right now versus what could wait. It gave me a clearer way to think through my niche, offer ladder, outreach, traction milestones, and weak points like defensibility and feasibility. It’s been especially useful because it doesn’t just give ideas, it helps surface the gaps in the business model so I can make better decisions faster. I’ve even referred clients to it because it’s valuable for getting early-stage ideas organized and stress-tested in a much more structured way.

Common questions

What’s free, and what does it cost?

Your Business Model Check is free: your canvas, your goal, and one full stress test of your idea, all 7 tests, with a report and the first fix for each. Then 1 re-test per test and 10 coach replies to work through it. It is a one-time trial, and your canvas and report stay yours. No credit card. Starter is $25/month to keep testing and fixing your idea. Pro is $50/month to prove customers will pay. 30-Day Money-Back Guarantee on any plan. No questions asked.

Which step is right for me?

Match it to where you are. Starter if you have an idea, Pro if you are building and need proof that customers want it, Power if you have paying customers and want to grow. Your free check confirms it.

What if I just have a rough idea, not a full business plan?

That’s exactly when to start. LEANSpark walks you through filling out a Lean Canvas from scratch. You don’t need a business plan, a pitch deck, or any prior framework knowledge. Just your idea.

Do I need to know Lean Canvas or any framework first?

No. LEANSpark teaches you as you go. It explains each concept in plain language, applied directly to your business—not as abstract theory.

What kind of businesses does this work for?

Any early-stage idea. SaaS, physical products, services, marketplaces, creator businesses—if you need to figure out whether people will pay for it, LEANSpark helps you test that systematically.

Join 1M+ founders who use Lean Canvas to validate their ideas. LEANSpark runs the tests and drafts the fixes. You decide what to change.
