I've referred a few folks to Kip who were looking for a therapist after struggling to find one elsewhere (in one case, I downloaded the app on their phone and just sent the person to the first meeting). So far, they're reporting positive things about the app and the experience.

One of the interesting things that Kip solves is discovery: it seems like they have a roster of prequalified therapists who follow evidence-based strategies. That's pretty interesting – the basic process of finding a qualified therapist who's a good fit via the usual methods (Google, asking people) isn't easy.
