Crustdata

Crustdata, a Y Combinator-backed, San Francisco company, provides real-time B2B data APIs covering 1 billion people and 60 million companies, purpose-built for sales, recruiting, and investment workflows rather than general-purpose data enrichment. It offers live alerts on personnel changes and company signals (promotions, hiring, funding events), bulk datasets on monthly/quarterly/yearly refresh cycles, and web-traffic analytics, company reviews, investment data, job listings, social posts, Form D filings, and news monitoring — accessible via REST API or CSV export. The company notably built its own go-to-market motion using its own APIs, reportedly growing from $600K to $10M ARR in 18 months, a concrete, checkable signal of the product actually working for its intended use case. Pricing combines API-based rates for real-time needs with dataset-based pricing for bulk enrichment; exact figures require checking their pricing page. Good fit for a sales, recruiting, or investment team that needs current, real-time signals on companies and people rather than static, quickly-stale contact databases.
