I’ve recently stumbled on an exciting niche that’s showing a lot of traction. The customers know very well how to use technology but the notion of joining forums / discussing their frustrations anywhere online just doesn’t seem to be something they consider doing. It’s all word of mouth.
My “luck” completely shifted when I stopped trying to find these users online and instead physically walked into a shop and started asking for opinions.
All that to say: I’m coming to feel that niches can more easily be found offline, even for SaaS type businesses. Just walk up and ask a business owner what they find annoying!
