## Research notes
Diffbot is a horizontal web-data/knowledge-graph company, not a purpose-built B2B contact tool - its GTM relevance is mainly company/entity-level enrichment, not email/phone finding. Free tier: 10,000 credits/month, no credit card required. Self-serve paid tiers start at Startup $299/month (250K credits), Plus $899/month (1M credits); Enterprise custom. Extracting a page costs 1 credit; exporting a full Knowledge Graph entity costs 25 credits.
