So I built the part I kept losing to doubt.

I always wanted to run my own business, and the ideas were never the hard part.

Launching them was. After a few attempts that never quite got off the ground, a habit set in: I would talk myself out of the next idea before it went anywhere. Not because I had checked it and found something wrong. Because I had not checked it at all, and doubt fills that space much faster than research does.

What I enjoyed was having the ideas. What I kept losing was the bit in the middle, where you find out whether one holds up before you commit a year to it.

So I built the part I kept losing to doubt, and made it check every idea harder than I ever did.

That is the seed Mumchimp grew from. It runs on ideas that are not mine now, and it publishes its workings either way: the few it clears, and the many more it rejects.
