I've been following Jon Yoonfook for over a year now who was inspired by Pieter as well.
He is a really talented developer and seems to whip out production ready websites in a few weeks, but after what seems like a dozen pivots he's only at $500 revenue per month (https://www.mojosaas.com/)
It's actually a bit discouraging because he is relatively high profile, great designer/developer, gets on the top of Product Hunt, etc., and yet has hardly any revenue for the amount of time he's spent trying to get something off the ground.
