VendorStacks vs Crustdata
Breadth across many signal types versus depth on one. We do a single thing — disclosed vendor relationships, with the source sentence attached — and publish a flat price for it.
Side by side
| VendorStacks | Crustdata | |
|---|---|---|
| What it is | A vendor-stack and subprocessor-disclosure API: give it a domain and it returns the vendors that company publicly discloses; give it a vendor and it returns the companies that disclose it. | Real-time B2B people and company data API aimed at AI agents, for sales, recruiting and investing. |
| Data source | Parses what companies publish about themselves — subprocessor lists, DPAs and vendor disclosures — and returns the quoted source row behind every match. | Aggregates roughly eight third-party sources — web traffic, reviews, investment data, social posts, news, Form D filings and job listings.source |
| Pricing | 1 credit per lookup, flat. Packs at $10 / $50 / $250. 25 free credits on signup, 5 free live scans a day, no annual contract and no sales call. | Dollar pricing is not published. Credit consumption rates are documented; the cost per credit is not.
|
| API access | Public REST API, self-serve key at signup, plus bulk endpoints and completion webhooks. | REST API for company, people, jobs and posts. Live real-time endpoints are enterprise-only and plan-gated.source |
When Crustdata is the better choice
People data and funding signals. If you need contacts, headcount trends or investment activity next to firmographics, that is their product and it is not ours.
When VendorStacks is
When the vendor you care about is behind the product rather than in front of it, and when you need the evidence rather than a confidence score. Every match we return carries the sentence the company published, so it can be checked rather than trusted. And when you want to try it without a call: 25 free credits at signup, $10 for 1,100 lookups after that.
