How Kustiq built this profile

Hybrid pipeline: deterministic verification + Claude reasoning

Live web rendering via Browserless headless Chrome, not a stale cached scrape.
Search intelligence via Serper API across {company site, LinkedIn, press, GitHub}.
Claude Sonnet 4.6 classifies vertical, segment, and growth signals; never used for facts.
12-factor churn engine produces a deterministic risk score with zero LLM calls at scoring time.
SMTP RCPT TO handshake verifies every contact at delivery time on full profiles (paid plan).

Read the full methodology in our LLM-readable reference or compare against the deterministic-vs-AI framework.
