Evidence of pain/interest
- r/SideProject URL shows 100+ upvotes and 26 comments asking for access (social proof that makers & growth people want it).
- Dozens of Reddit threads in r/SaaS, r/Marketing, r/PublicRelations ask “How do you monitor Reddit for keywords?” or “What’s the best Reddit listening tool?”
- Example posts (titles only, scraped but content JS-blocked):
– “How To Monitor Keywords on Reddit?” (r/SaaS Feb-24)
– “Anyone here actually monitoring brand mentions on Reddit? How do you do it?” (r/marketing Aug-24)
– “Which tool to monitor Reddit for keywords is the best in 2025” (Devi blog Dec-24 – but shared on Reddit)
