This is Customer Validation

Last week I had the pleasure to attend the Lean Startup Michigan conference in Grand Rapids.

At lunch the organizers set out box lunches.  We could choose from several different kinds of sandwiches.  I got out there late, and here is what I found.

Can you identify which meal was not popular (the value proposition hypothesis that failed) – and those that were popular (the hypotheses that were confirmed)?

p.s. for what it’s worth, ham didn’t cut it with the Lean Startup crowd.
