Stories like this give me hope as a bootstrapped founder. One year into building a thing (skillsapp.com), we have users but no hockey-stick on our charts. It takes time to refine and refine some more. Pivots aren't always about solving the same issue a different way. It's unsexy, but sometimes it's a long learning slog until you hit on the right formula.
Respect to them for having the fortitude and not giving up.
