This post seems like a success story, so far. So how is not interviewing them a bug? If you are seeking startups who need help identifying how to get customers and how to create products people want, then it seems that Codiqa doesn't fit. Codiqa has customers and is making products people want.

Said another way, the delta between where Codiqa stands today vs. where they would be had they been interviewed does not seem as large an opportunity as probably the opportunities you made for the companies you did select. Therefore, I'd say there's no bug.
