Starbridge

Starbridge is an AI-powered go-to-market and sales-intelligence platform for vendors selling to the public sector and education — government agencies, K-12 school districts, and higher-education institutions. It surfaces early buying signals (RFPs, board meetings, purchases, conferences, contact and job changes), scores and enriches target accounts, and drafts personalized outbound and RFP responses. Starbridge exposes an external REST API (Bearer API keys), Ed25519-signed webhooks, and a hosted OAuth MCP server, plus published Agent Skills, so buyer intelligence can be pulled into CRMs (Salesforce, HubSpot), Slack, Zapier, and AI agents. Backed by Craft Ventures.

Starbridge publishes 6 APIs on the APIs.io network, including Bridges API, Buyer API, Columns API, and 3 more. Tagged areas include Company, Ai, Sales Intelligence, Go To Market, and Public Sector.

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

Starbridge’s developer surface includes authentication, changelog, documentation, API reference, getting-started guide, engineering blog, signup flow, and 30 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector 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.
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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/starbridge: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
