Good writeup, but I can't help but laugh a bit at the outcome pivot:

"We decided to build a solution to this problem — FundaMine, a community to help professionals interact with others in their profession."

Literally the "well, we don't know how to make what people want, so let's address what we as startup people want" outcome. Literally.

Agreed! Making what you yourself want is actually a legit thing to do in a startup as long as you know that there are more people like you!
