Crunchbase alternatives
The highest-scoring alternative to Crunchbase is Apollo at 64/100 on the AgentReady, against 31/100 for Crunchbase.
All scored in Company & Contact Data APIs.
What Apollo does that Crunchbase does not
Apollo passes clear canonical domain, public docs discoverable, llms.txt published, mcp discoverable, machine-readable metadata, authentication documented, pricing understandable, limits / constraints documented, self-service signup, agent-compatible signup flow, free trial or free allowance, official python sdk, mcp integration available, observable execution, agent compatibility verified, and Crunchbase fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Crunchbase fails clear canonical domain, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata, structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, official python sdk, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Crunchbase loses the points
| Pillar | Crunchbase | What it measures |
|---|---|---|
| Discover | 47 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 15 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 25 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 35 | Rate-limit headers, errors, status, and behaviour under load. |
Crunchbase is weakest on understand at 15/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Crunchbase may still be the right pick.
What an agent runs into with Crunchbase
These are the findings from the last audit on 2026-08-22. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Make signup self-serve; an agent cannot sit through a sales call.
- Ship an MCP server so agents can call you as a tool.
- Make docs reachable without auth or navigation gymnastics.
- Publish MCP install instructions so agents can discover the server.
- Publish an OpenAPI spec so agents can generate a client.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
