Crossbeam

Crossbeam is the leading Ecosystem-Led Growth (ELG) platform: a secure data-collaboration network that lets companies compare CRM data with their partners to uncover shared customers, overlapping prospects, and co-selling opportunities without exposing sensitive records. It turns partner-sourced overlaps, populations, and real-time signals into "Ecosystem Intelligence" that flows into GTM tools and AI agents. Crossbeam exposes this data through a REST Partner API (OAuth 2.0), real-time Signals webhooks, a remote MCP server, and in-app AI Chat, backed by SOC 2 Type II, GDPR, CCPA, and PCI DSS compliance.

Crossbeam publishes 1 API on the APIs.io network. Tagged areas include Company, Ecosystem-Led Growth, Partnerships, Account Mapping, and Co-Selling.

The Crossbeam catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Crossbeam’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, pricing, and 23 more developer resources.
