MentionCatch

The author says they are 17 and built a SaaS called MentionCatch. It finds people on Reddit who are already asking for a product like yours, qualifies them with AI, and hands you a reply that is ready to post. The product was built on Reddit's RSS feeds.

MentionCatch launched on August 30. The author says their first customer paid 3 hours later and that September was their best month yet: $65 revenue, $76 MRR and 12 active trials. The author's next goal is $100 MRR. The revenue and MRR figures are recorded separately as stated and are not reconciled; the $100 is a goal, not realized revenue.

Reddit turns off RSS feeds on November 13. The author writes that new requests for Reddit's public API already stopped on October 31 and that what remains of the public API closes in March 2027; they do not have API access and cannot get it now. The author notes that GummySearch, a well-known Reddit research tool, shut down a year earlier because it could not get a commercial API license from Reddit.

The author's response is to turn MentionCatch from a Reddit lead tool into a multi-platform lead discovery tool, adding X, LinkedIn, Hacker News and more one platform at a time, while keeping the core flow of finding the question, qualifying it and writing the reply. The author does not promise a launch date for the new version. In the same thread the author said they will cache harder and only poll high-intent content often to keep costs low.

The product depended entirely on Reddit RSS feeds, which shut off on November 13, and the author has no Reddit API access. The multi-platform version has no launch date. Revenue after September, the AI model used, customers and acquisition channel are undisclosed; the five images in the article were not read for this record.
