We recently soft launched Clearcut to help gather structured user feedback to reach product-market fit faster.
My co-founder and I built this because we fell in love with the "how disappointed would you be to not use Product X?" methodology towards measuring product-market fit, but found implementing it was a pain.
We kept on forgetting to send it out to new users, which meant we were missing critical feedback opportunities. Even when we did send it out, it was entirely manual, including manually following up to get more responses. And then we had to do manual analysis + manually segment users by responses.
