I'm also a huge fan of the Mom Test!

In your specific customer interview, I would probe deeper. For most real problems people have, they've hacked together a makeshift solution. It may work, but it doesn't mean it works well. It doesn't mean the problem is solved.

I would ask "how is it like working with this larger company?". If you have any specific pain points working with larger companies that you've seen, I'd ask "how do you deal with pain point X?"

I doubt someone would say something is their biggest problem if they have a great solution for it!
