Strengths and weaknesses
- +Large database (275M+ contacts, 73M+ companies) with strong US coverage (~80–88% match accuracy)
- +Aggressive pricing that undercuts ZoomInfo/Lusha-class incumbents for comparable breadth
- +Bulk enrichment endpoints (up to 10 people or companies per call) reduce call volume
- –Data accuracy drops sharply outside the US (~60–73% in EU/APAC/LATAM); stale titles common
- –Phone numbers cost 8 credits each yet user-reported direct-dial accuracy is only ~50–70%
- –Credits expire every billing cycle with no rollover and no refund on unused balance
- +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
