Strengths and weaknesses
- +Pay only for successful matches (HTTP 200), missed lookups are not billed
- +Very large breadth: 3B+ person profiles across 200+ countries and ~70M company profiles
- +Developer-first REST API with Elasticsearch-style search queries praised as flexible and well-documented
- –Data refreshes roughly monthly, so job titles and employers can be weeks-to-months stale
- –Heavy reliance on LinkedIn means non-LinkedIn people are under-represented and some self-reported titles leak through
- –Verified emails and direct-dial phones often require extra Person Identify calls at higher per-match cost
- +Deepest enterprise B2B database among enrichment APIs: ~321M+ contacts across 104M+ companies with strong direct-dial and mobile phone coverage
- +Excellent accuracy and coverage for US/North American enterprise contacts (VP+ at 200+ employee firms)
- +Asynchronous Scaling APIs with webhook callbacks handle large batch enrichment jobs cleanly
- –Opaque, sales-gated pricing with five-figure annual minimums (~$50K/year for the full API)
- –Coverage and accuracy drop sharply outside the US/Canada
- –Data freshness is cycle-based (~90-day validation refresh), not real-time, leading to email bounces in cold outreach
