Crustdata

What it does

Crustdata provides APIs that deliver live company and people data, designed to power AI agents. Through its REST API, users can search, enrich, or monitor individuals and organizations in real time. Crustdata tracks events such as job changes, promotions, skill additions, social posts, funding rounds, headcount growth, and web traffic changes. The platform also offers a full dataset (12M+ companies, 250M+ people) for bulk delivery and CSV exports. Notably, Crustdata now integrates with Claude via the Model Context Protocol (MCP), enabling Claude to access real-time people and company data directly.

Who it is for

Crustdata is built for AI developers, sales teams, recruiters, investors, and platforms that need up-to-date company and people information. Specific use cases include powering AI SDRs with live signals, automating sales workflows, enriching CRM or ATS, tracking competitors, screening investments, and monitoring portfolio companies. The platform is also suited for internal sales teams that need real-time account triggers, and for recruiting platforms that want immediate alerts on candidate movements.

Why it matters

Timely access to people and company data can drive better decisions in sales, recruitment, and investment. Crustdata claims to be “the only platform providing truly real-time data.” By offering live alerts (e.g., “Podium web traffic increased 108.4%”, “Taylor Morgan was promoted to CMO”), users can act on opportunities or risks as they happen. This real-time capability is increasingly important as AI agents and automation rely on fresh data to generate emails, update records, or trigger workflows automatically.

Launch signal

Crustdata is backed by Y Combinator and joined the YC batch. The company has a presence on Product Hunt with a 5.0 rating and 2.6K followers. Its integration with Claude marks a notable launch signal, allowing the AI assistant to query live data. The website also lists several customer logos, indicating adoption among sales and recruitment platforms. The company offers a full dataset updated monthly for bulk use, showing a scalable data offering.

Brand and naming

The name “Crustdata” combines “crust” (suggesting a foundation or core layer) with “data,” implying essential, underlying information. The brand positions itself as the data layer for AI agents, emphasizing real-time and freshness. The tagline “People and company search APIs built for AI agents” clearly targets the developer and AI ecosystem. The brand is memorable and aligned with current trends in AI and automation.
