What do you think about Lean Canvas?

They say "90% of startups fail". And even tell us top reasons of those failures: Wrong Market, Lack of Research, Money Ran Out, Bad Partnership, Bad Marketing, Not an Expert, etc.

And I agree. I was really happy to meet Lean Canvas as it was a very simple tool to break your idea into pieces and find out all the risky moments with your upcoming business. With that you can focus on validating the riskiest ones with your MVP.

I use Lean Canvas for my every idea. But this tool means a little if you are alone.

1. You can not fill all the sections because you don't know what to put there
2. You don't know who to reach to get relevant advice
3. You don't know what actually should be your first step after you completed this canvas.

Have you guys used Lean Canvas? What do you think of it? Maybe you even helped someone with Lean Canvas? I would be happy to hear your thoughts and stories.
