Find the weak spots before you build
Your business model gets scored across 7 dimensions. LEANSpark finds the gaps, suggests fixes, and helps you prioritize what to test first.
Scored 0–10 across Clarity, Desirability, Viability, Feasibility, Defensibility, Timing, and Mission.
Run experiments, not guesses
A structured 90-day cycle: pick your riskiest assumption, design an experiment, run it, and decide what to do next—all guided step by step.
6 sprints in 90 days. Each cycle sharpens your model or gives you a clear signal to change course.

▶ Import a Lean Canvas from Your Landing Page
Point LEANSpark to your landing page and get a complete Lean Canvas in seconds.
▶ Stress-Test Your Lean Canvas
Get a 7-dimension score of your business model with specific fixes prioritized.

Writing good interview questions is hard. Most founders either lead the witness or ask questions so broad they learn nothing. The result: false validation that wastes weeks.

Common questions
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 puts that methodology on autopilot.
