Strengths and weaknesses

Apollo.io logoApollo.io
  • +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
People Data Labs logoPeople Data Labs
  • +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
