Not Every Mention Is a Lead. SignalPipe Knows the Difference.
Three-stage AI scoring — keyword gate, embedding similarity, LLM swarm — surfaces real buyers and rejects everything else.
The hardest part of social selling isn't finding mentions — it's knowing which ones are worth your time. A keyword alert on "looking for a CRM" will return irrelevant posts, sarcastic comments, competitor discussions, and the occasional real lead buried underneath.
SignalPipe's signal scoring runs three stages in sequence, with each stage being more expensive but more accurate than the last. The keyword gate eliminates ~85% of posts before any API calls are made. The embedding layer measures semantic similarity to your buying-intent anchors using OpenAI's text-embedding-3-small. The LLM swarm applies three independent AI judges at different skepticism levels.
The result is a stream of leads where nearly every post is genuine buying intent — not a fire hose of noise you have to sort through yourself.
How it works
Keyword gate
Fast, cheap pre-filter. Any configured buy-signal keyword must appear before a post is scored. Eliminates ~85% of API costs.
Embedding similarity
OpenAI text-embedding-3-small measures cosine similarity against your anchor sentences — buyer-perspective phrases like "I need X" or "looking for alternative to Y." Semantic match, not just keywords.
LLM swarm judgment
Three AI judges (Optimist, Analyst, Skeptic) evaluate each lead independently. A hard skeptic veto at score < 0.3 suppresses any signal the most skeptical judge dismisses entirely.
RL weight learning
Every approval and rejection you make adjusts the per-product RL weight multiplier. Over time, similar leads are scored higher or lower based on what you've found valuable.
