Needle is a buyer-intent search platform that scans public communities including Reddit, Hacker News, Stack Overflow, GitHub, X, and LinkedIn to surface high-intent leads in one unified workflow. It ranks results by buying intent rather than raw keyword matches, filtering out irrelevant noise automatically. Users can run manual one-off searches or schedule automated monitoring to track brand mentions and competitor signals. Needle integrates with CRMs like HubSpot and Pipedrive and supports notifications via Slack, Discord, and Google Chat, making it suitable for founders, sales teams, and marketers doing community-led customer discovery.
