Lidar
Scans Reddit daily for people describing your product's problem and sends you the threads
Lidar reads your site, works out who it's for, picks relevant subreddits, and scores new posts there against your product daily, surfacing only the ones describing your specific problem with a quote and a link to reply. You write and send the reply yourself — Lidar never posts or messages on your behalf, and it never connects a Reddit account. It's €14 a month per product after a 7-day free trial with no card required upfront, and the maker calls it explicitly a 'high-intent, low-volume' channel — a handful of matches a day for most products.

What holds up
- +7 days free with no card required before you commit €14/month
- +Never posts or messages on your behalf — you see the quote and write your own reply
- +First matches typically land within an hour of pasting your URL, per the FAQ
Mind the limits
- −Explicitly low-volume — just a handful of matches a day for most products, fewer in quiet niches
- −Locked to Reddit only, so it misses problem-describers on other platforms
