People want to connect with nearby others who share niche hobbies or interests, but existing apps are either too broad or too dating-focused.
Create an app where users join hyper-local groups based on interests (like photography, hiking, or board games) within walking distance.
Monetize through local business sponsorships and promoted events.
Start with a single city and focus on 2-3 popular interest categories.
The risk is achieving critical mass - focus on college towns or dense urban areas first.
