Show HN: Problem Spotter – Discover Reddit communities and track growth

2 vadimkomis 0 7/23/2025, 6:00:19 PM problemspotter.co ↗

After nearly a year of development, I've launched Problem Spotter - a tool that helps you discover relevant Reddit communities and track their growth patterns.

Key features: - Search across subreddits by topic/keyword - Monthly subscriber growth tracking and trends - Audience overlap analysis

Built this because I was manually hunting through Reddit for market research and community validation. The existing tools either didn't have good search or lacked growth data.

Would love feedback from the HN community - especially if you use Reddit for research or community building.
