Lead Generation
SaaS, open source and skills for lead generation work — with the limits of each written down.Before you pick
What decides it
Match rate on your segment decides this, not database size; coverage thins outside North America and on smaller companies. Benchmark against accounts you know.
What to avoid
Credits meter attempts, not matches — misses and every waterfall step still bill. Ask what a failed lookup costs before you size the plan.
What is changing
One-time list pulls are being replaced by continuous re-verification across multiple providers, because records decay monthly. Freshness at send time is the new claim.
