As answered by people managing Slack and ReplyGain.
ReplyGain's answer:
ReplyGain is the only social listening tool purpose-built for indie hackers and SaaS founders. Instead of tracking brand mentions like legacy tools, it finds posts where someone is actively asking for a product like yours, across Reddit, Hacker News, X, and Bluesky. Every lead gets an AI intent score (0-100), and you can generate natural-sounding replies with one click. Paste your URL and AI auto-generates keywords and subreddits to monitor, zero manual setup
ReplyGain's answer:
Traditional social listening tools like Brand24 and Mention are built for enterprise brand monitoring, tracking who talks about you. ReplyGain flips that: it finds people already asking for what you built, even if they've never heard of you. It's built for founders, not marketing teams. The AI generates replies (not corporate-sounding AI slop), and pricing starts at $29/mo vs $100+/mo for competitors. Plus it covers Hacker News and Bluesky, which most competitors ignore entirely.
ReplyGain's answer:
Indie hackers with SaaS products, startup founders (pre-Series A), solo founders managing multiple products, small agencies with 3-10 clients, and freelancers like SEO experts or designers. Anyone who needs to find potential customers on social platforms but doesn't have time to scroll Reddit for 3 hours a day.
ReplyGain's answer:
ReplyGain was born from a founder's frustration with manually searching Reddit every day for potential customers. Scrolling through thousands of posts, most irrelevant, hoping to find the one person asking for exactly what you built, a 3-hour daily time sink. So we built an AI that does it in minutes: scans multiple platforms, scores posts for buying intent, and generates replies that actually sound human. What used to take 90 hours/month now takes 5.
