Market research for startups with limited resources

Since I'm French, I can't say much on the English writing. Though I found it very clear and easily readable. I'm very interested in this topic because I'm in the process of trying to evaluate my business project and, of course, I have no money.

I liked your two step approach that consisted in a first tour with simple interviews and a second tour with questionnaire to objectify the collected data.

A recent post on Hacker News has pointed out the crucial importance of the business validation to evaluate the right company valuation which it self determines if the investing is an attractive deal or too risky.

Business validation is a topic that is not well covered in startup informations available on the web.
