The story

Founders guess what their app could earn. Grador makes the guess explicit, with a range instead of one number.

The estimate combines traffic, public claims, app store data and priors, then runs 2,000 simulated paths for growth and failure. A count on a page is a lower bound, not revenue.

The hard part is honesty about error. On a set of known revenues the median miss is 0.31 in log10, about two times. Some misses are worse, up to 7.7 times, and they stay on my list of open work.
