Strengths and weaknesses

Crustdata logoCrustdata
  • +Genuine real-time / live web indexing, returns data for untracked companies within minutes rather than serving stale batch data
  • +Watcher API + webhooks push change signals (job changes, funding, promotions) the moment they're detected
  • +Clean, fast, well-documented REST API that reviewers say makes integration 'almost effortless'
  • –Paid plan pricing is opaque, no named tiers or list prices published; heavier endpoints gated behind enterprise/demo requests
  • –Credit-based model can create unpredictable costs without active monitoring
  • –No first-party SDKs, integration is raw REST (client libraries are community/third-party only)
FullContact logoFullContact
  • +Multi-field enrichment: accepts many identifier types (email, phone, name+address, social URLs/usernames, MAIDs, plus Resolve PersonIDs) to lift match rates
  • +Deep attribute coverage, 900+ appendable data attributes via Person Insights Bundles (demographics, household, employment history, affinities, shopping habits)
  • +Tunable confidence: ML 'Belief Vector' lets callers set confidence thresholds per request to balance precision vs. match rate
  • –Real-world match rates often far below the advertised 93%, reviewers report ~40-50%, especially outside the U.S.
  • –Data-quality complaints of false positives in age, employment, and education fields, with no data-freshness timestamps on attributes
  • –Rate limit (~600 queries/min) too low for large batch enrichment jobs
