Cabal

Cabal is an AI-powered relationship-intelligence and warm-introduction platform that turns an organization's professional relationships into warm introductions. It infers connections across millions of professional records without CSV uploads or calendar syncs, letting teams "ask who's connected to anyone." Cabal serves VC platform / deal-sourcing teams, sales organizations, and investor-relations and partnerships teams, and ships Cabal Mail for bulk personalized outreach (company updates, LP communications, strategic asks). The relationship graph is queryable through in-app chat, Claude and ChatGPT via the Model Context Protocol (MCP), a Slack bot, or an API. Backed by Craft Ventures. This profile was enriched by the API Evangelist pipeline from Cabal's public surface; the company advertises API and MCP access but does not publish a public OpenAPI spec or open developer reference (both are account-gated).

Cabal is profiled on the APIs.io network. Tagged areas include Company, Software-as-a-Service, Relationship Intelligence, Warm Introductions, and Venture Capital.

Cabal’s developer surface includes engineering blog, pricing, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
