Sources
Sonar monitors 18 curated subreddits including r/startups, r/SaaS, r/selfhosted, and r/programming. Plus Reddit global search and Hacker News via the Algolia API. New signals every 4 hours.
Scoring
Each signal gets a 0–100 demand score combining upvotes, comment count, recency, and willingness-to-pay indicators like “I'd pay for this” or “take my money.”
Classification
Every signal is classified into 3 types: Solution Request (someone looking for a tool), Pain Point (frustration with the status quo), or Money Talk (discussing willingness to pay).
