  • A phone number verification API: what is it?
    As the name implies, phone confirmation APIs are used to verify contact information. Phone numbers are checked for validity and continued use by verification APIs and services (i.e., they exist).

  • A Practical Guide To Entity Resolution in Python (No Database, No Machine Learning)
    Some display names need a lookup table, not fuzzy strings. Pairs like Investing.com / Fusion Media Limited or Lyrie.ai / OTT Cybersecurity Inc. Share almost no tokens, so WRatio stays low and that's correct behavior. For irreconcilable aliases like that you still want GLEIF, Clearbit, or simply a maintained slug โ†’ legal_name map.

  • Enriching Free Trial Signups: The PLG Data Stack for Turning Inbound Users Into Qualified Pipeline
    Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ€” the most permissive of the major providers โ€” gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains.

    A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ€” the tradeoff is more stale titles in the result set.

    Match rate of 38% in my test, but the data quality on what it does match is solid: title, seniority, industry, company size all returned cleanly. If you're already in HubSpot and enriching form fills in-place, Clearbit/Breeze is probably your lowest-friction option even at lower match rates. If you're not in HubSpot, there's no reason to choose it over PDL or Prospeo. - Source: dev.to / 2 months ago
  • Auto-Enriching Your CRM on New Contact Creation: A No-Code Webhook Playbook
    One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ€“8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 3 months ago
