I found the breakdown between customer and problem hypothesis very interesting. I'm currently working on a tool to store ideas(blatant self promotion: http://www.255ideas.com). I was very interested in the customer/problem/solution hypothesis model. I think having directed fields may help guide the user in writing down their idea. But I also have to wonder, does it force the idea into a structure that it wouldn't take otherwise? Perhaps it would filter ideas that aren't focused on creating on solving a problem. Awesome ideas might not make the cut, for example, draw something.

IMO the most effective way to show an idea is with a prototype. It's also the hardest.

I also like the ability to add assumptions that are validated/invalidated. The focus on business plan is very cool.

Thanks for the link.

I did a Lean Startup Machine workshop the other weekend where we learned to utilize this board. It was an awesome workshop and I learned a lot.

This board helps you iterate over your idea. It's like agile development, but focusing on the idea.

Whenever I see tools like this I look up at my whiteboard and go "this does it better" :-)

Never underestimate the power of a big chunk of wall you can write on and stick things to.

seems inspired by this: http://www.ashmaurya.com/2010/08/businessmodelcanvas/

Great tool!
