Cleverspend

It takes a lot of time, and lots of reach outs to convert someone who would give you a chance, but you eventually get one. Learn to hear a lot of No, even from people you have worked with before.
One thing that I learned is: followups are very important. You have to follow up.

We started cleverspend after going through a lot of existing product ideas. We zeroed down on a few and started validating them in the market.
We were looking at TAM, our ability to capture that market, and in the worst case, how much we will be able to capture.
