Most teams find out a company was in-market about three weeks too late. Buying signals fix that. They are real-world events, a funding round, a new VP of Sales, a first-ever job posting in a new function, that tell you a company just changed in a way that creates need, budget, or urgency. CUFinder tracks 99 signals across company pages, people moves, and composite patterns, refreshed daily against a base of 1B+ people profiles and 85M+ company profiles. This documentation is the complete reference: every signal has its own page with the exact trigger condition, stored fields, magnitude, interpretation, and an outreach playbook.
