I have been going hard on user interviews and idea validation since reading The Mom Test. I can't recommend it enough! The only problem is that I've never done this many interviews in such a short period of time before and trying to synthesize all that data to tell a cohesive story has been a nightmare. None of my old card-sorting, Post-It-noting methods were working. So I took a step back and dumped everything into Airtable. Now I can sort all of my insights by theme, category, and customer segment. I sat down with my co-founders yesterday and was able to quickly and concisely answer questions about user pain-points.
