Crustdata
Crustdata is a San Francisco company that supplies real-time company and people data through clean APIs and webhooks built for AI agents. Founded in 2024 and part of Y Combinator's Fall 2024 batch, it pulls live data from many primary sources so AI SDRs, recruiting tools, and investment platforms can find the right person, watch for job changes and funding rounds, and act on fresh signals instead of stale databases.
People Data Labs
People Data Labs is a data-as-a-service company that sells clean, structured B2B data through developer-friendly APIs. Instead of selling dashboards or seats, it sells the raw material - billions of professional and company records that engineers, data scientists, and product teams use to build their own tools for recruiting, sales, marketing, identity verification, and AI. Founded in 2015 and headquartered in San Francisco, the company positions itself as the data layer underneath other companies' products rather than a competitor to them.
