What happens in the fit call

Talk to us about your software for fifteen minutes, by video. You tell us what you are building and where it hurts. We tell you whether one of our offers fits: an expert review, a UX audit, the UX design subscription or a studio project, or whether you need something else entirely.

If it fits, you get a short written next step within one working day, with scope and a fixed price. If it doesn't, you still leave with a recommendation.
