Crunchbase

Add Crunchbase to your product for your customers, and give your AI agents governed access to it.

Crunchbase's v4 API is field-selective: entity and search calls return almost nothing unless you pass field_ids naming exactly which fields you want, so a sparse-looking response is usually a missing parameter rather than missing data. Entities are addressed by permalink, a slug such as airbnb rather than a numeric id, and permalinks can change when a company is renamed, which quietly breaks stored references. Search is a POST of query predicates over field ids, and paging uses an after_id cursor rather than an offset, so you cannot jump to page five. Related records like funding rounds and investors are fetched as named cards hung off the organisation rather than joined into the entity response. Rate limits are enforced per key on a daily basis and the licence constrains how much data you may retain, so caching strategy is a contractual question as much as a technical one. fastn holds each customer's key, keeps field selections consistent and maintains the connector.

In your product

Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.

Let a customer connect their own Crunchbase key so lookups run under their own licence and daily limit.

Enrich an account record with headquarters, headcount band and last funding round on creation.

Watch a saved search for newly funded companies and raise them into your own pipeline.

Resolve a company name typed by a user to a stable Crunchbase permalink before storing it.

For your AI agents

Governed, audited access for the agents you build, through the MCP server.

Ask an agent for a company's most recent funding round and lead investor, with each call audited per tenant.

Have an agent check whether a prospect has been acquired before an outbound sequence starts.

Let an agent build a shortlist from a funding-stage and region query and hand back the permalinks.

Set up Crunchbase in 4 steps

  1. 01Enable the Crunchbase connector from your fastn dashboard.
  2. 02Have each customer authorise their own Crunchbase account, so calls run under their credentials rather than a shared key.
  3. 03Decide which lookups, results and reports your product needs, map those fields, then enable the actions and triggers you want.
  4. 04Call it from your product and expose it to your agents through the same governed connection.

Why teams use the Crunchbase integration

What you get by embedding it with fastn instead of building it yourself.

  • Ship a Crunchbase integration without building it. Your customers connect their own Crunchbase account inside your product and work their lookups, results and reports there, with no per-customer code on your side.
  • Handle the part that actually costs time: these are metered read sources, so an uncached lookup on every page view burns the customer's allowance. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Crunchbase update is not your on-call problem.
  • One integration serves your product and your agents. The same governed Crunchbase connection powers in-product features and gives AI agents scoped, audited access, so you answer questions from an authoritative outside source without holding that data yourself without wiring it twice.

Crunchbase integration FAQ

How do I add a Crunchbase integration to my product?

Enable the Crunchbase connector in your fastn dashboard, then let each customer authenticate their own Crunchbase account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Crunchbase client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Do my customers each connect their own Crunchbase account?

Yes. Every connection is scoped to the individual customer, so each authorises their own Crunchbase account and only ever sees their own lookups, results and reports. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.

Can AI agents use this Crunchbase integration?

Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Ask an agent for a company's most recent funding round and lead investor, with each call audited per tenant.

Who maintains the Crunchbase integration?

fastn does. When Crunchbase changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.

Whose credentials does a Crunchbase lookup run under?

Each customer's own. Quota and cost land on the customer that caused them rather than on a shared key you have to meter and re-bill, and one heavy customer cannot exhaust another's allowance.

How should Crunchbase results be cached?

Per tenant, with a window that matches how fast the underlying data actually moves. Crunchbase is a read source rather than a system of record, so the same query returns the same answer until the source changes, and caching is the difference between a sustainable integration and one that exhausts a customer's allowance on a busy page.

What can I build with the Crunchbase integration?

A common starting point: let a customer connect their own Crunchbase key so lookups run under their own licence and daily limit. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.

How much does the Crunchbase integration cost?

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Crunchbase does not change your per-connector cost. You can start free with 3 connected accounts.
