The Yalc default for company and people data. Native MCP integration means Claude calls Crustdata directly. 1 billion profiles is more than ZoomInfo, fresher than Apollo, designed for code first workflows.
Crustdata is a B2B intelligence database with 1 billion people profiles and 60 million companies, plus signals (job openings, news, financing events, technographics, social posts, web traffic). The pitch is "freshest, most trusted data for AI agents," and the API surface reflects that: REST endpoints for search and enrichment, plus a Model Context Protocol server that lets Claude (and Claude Code) query Crustdata directly without manual API plumbing.
For Yalc workflows, Crustdata is the canonical intake node. When you tell Yalc "find me 50 fintech CFOs in Series B SaaS in Germany," it's Crustdata that runs the search. When you want to enrich a list of LinkedIn URLs with current employer and seniority, that's Crustdata too. When you want a webhook the moment a target account posts a hiring signal, that's Crustdata's Watcher API.
Crustdata sits at the **intake** node in Yalc's GTM topology. It's where outbound starts. Most Yalc prompts that begin with "find me…" hit Crustdata first.
Because Crustdata ships an MCP server, the integration with Claude Code is unusually direct. Yalc skills don't need to wrap the API as much as point Claude at the MCP and let it compose queries.
The intake node. Yalc's first call when sourcing accounts or people. Output flows downstream into FullEnrich (for missing emails) or directly into a sequencer if Crustdata's enrichment already returned what's needed.
Copy paste prompts for Claude Code that invoke Crustdata.
Yalc has deep Crustdata integration. The Crustdata MCP server is registered, which means Claude can call any Crustdata endpoint directly during a Yalc session. Plus a first party Yalc skill wraps common operations (people_search_db, company_enrich, watcher_create) with the credit safeguards memo'd in Othmane's playbook.
✓ Yalc skill available. View on GitHub.Crustdata pricing is not public on the homepage. The vendor offers demos and tailors pricing to volume and use case. Expect a credit based model where company searches are cheap (around 1 credit each), people searches and enrichments cost a few credits, and live API calls (LinkedIn freshness lookup) cost more.
The right way in is the demo booking link. Rohit and the team customize for AI agent workloads, which is the relevant context for Yalc.
New accounts often get a starter credit allotment to test queries.
Monthly credit budget, scaled to volume. Talk to sales for current rates.
Dedicated infrastructure, higher volume, SLA. Right for high frequency agent workloads.
Crustdata ships a Model Context Protocol server. You register it with Claude Code, and Claude can then call Crustdata's people_search, company_search, enrich, and watcher endpoints during a Yalc session as if they were native tools. No HTTP plumbing per query.
Crustdata's EU coverage is strong (sourced from public LinkedIn plus other open data plus partner feeds). ZoomInfo has historically been weaker in EU due to GDPR posture. For DACH, France, UK, Crustdata is competitive. For deep verified contact data in EU, run a FullEnrich waterfall on top.
Each operation costs a small credit count. Company identify is free, company search is around 1 credit, people search around 3 credits per 100, person enrichment 2 to 5 credits. Yalc skill enforces a pre flight check that estimates cost before running the call.
Yes, via the Watcher API. You define a query, Crustdata runs it on schedule, and if the result set changes, it POSTs to your webhook. Use it for "alert me when target accounts post a hiring signal" or "alert me on Series B announcements."
Static firmographics (HQ, industry, employee count) refresh on a slower cadence (monthly to quarterly). Signal data (jobs, news, posts) is near real time. The vendor's claim of "freshest data" is most accurate for the signal layer.
Not publicly. New accounts typically get starter credits when they book a demo. Best to use the demo link to negotiate a starter allotment.
