Finding your first 100 paying customers requires being in the right room when potential buyers ask for help. Today, those buyer conversations happen in public communities: Reddit, Stack Overflow, Hacker News, GitHub, YouTube comments, and specialized forums.
Instead of waiting for prospects to fill out a web form, buyer intent discovery tools help B2B SaaS founders identify active conversations where buyers are explicitly asking for tool recommendations.
Here is an honest breakdown of top social listening and intent discovery software for 2026.
