Why 73% of Founders Build the Wrong Thing
Because they skip business model stress testing
I spent 9 months and $50K building CloudFire, a photo-sharing app. Beautiful product. Perfect execution. One problem: the business model was completely broken.
I needed millions of leads for a $49/year product targeting busy parents. I could have caught this with some early-stage business model math.
That experience led me to develop a 7-dimension stress-test framework — covering everything from mission and desirability to viability, feasibility, and defensibility — that became the foundation for Running Lean and Lean Canvas. Over 25,000 founders have used it to validate their ideas 10x faster than the industry average.

Frequently Asked Questions
What if I already have a business model?
Perfect — BMD Challenge will stress-test it. Most founders discover blind spots they didn't know they had. The 7-dimension framework evaluates your model from angles you likely haven't considered, which is exactly why founders who already have ideas get the most value.
Is this part of a larger system?
Yes. BMD Challenge is Step 1 of a 3-phase founder journey:
- Step 1: Business Model Design (BMD Challenge)
- Step 2: Demand Validation Playbook
- Step 3: Value Delivery Playbook
All three are now included free with LEANSpark.
Is this self-paced?
Yes. All 10 modules and every micro-lesson are available immediately. Work through them at your own pace — most founders complete the challenge in 2–4 weeks spending about 30 minutes a day. A guided email series helps keep you on track.
What if I just want the basics first?
Start with the free Continuous Innovation Foundations course. It includes 3 free canvas accesses. Return to BMD Challenge when you're ready to go deeper.
How is this different from other business courses?
BMD Challenge is not theory-only — it's systematic practice with the Lean Canvas creator. The framework is continuously evolving with new techniques not in published books. You get lifetime access to all current and future content.
What if I'm not ready to start a business yet?
BMD works with or without an existing business idea. You'll learn a systematic approach for evaluating future opportunities and build an entrepreneurial success foundation.
