Bloomberg Beta
Bloomberg Beta is an early-stage venture capital firm that invests in companies making business work better, with a particular focus on the future of work, machine intelligence, and technologies reshaping how companies operate. Founded in 2013 and capitalized entirely by Bloomberg L.P. (though it invests independently), the firm runs approximately $450M across five $75M funds - its 2013, 2016, 2019, and 2022 vintages plus a first opportunity fund for follow-on investments in existing portfolio companies. Bloomberg Beta writes seed and early-stage checks (roughly $1M-$7M), leads or co-leads rounds, and is known for operating in public: its entire "operating manual," investment criteria, and full publicly announced portfolio live openly on GitHub, and it open-sources its Series Seed, SAFE, and note investment documents. The firm operates from San Francisco (140 New Montgomery St.) and New York (731 Lexington Ave.), backs founders across developer tools, infrastructure, security, AI, and enterprise software, and measures itself primarily on founder NPS.
A small, focused seed book of the infrastructure agents will consume, scored the way a machine reads it — that has not yet been packaged for agents itself.
Bloomberg Beta has 257 portfolio companies tracked on the APIs.io network, of which 254 (99%) publish APIs indexed here.
Its highest-rated API providers on the network are Stedi, LaunchDarkly, Slack, GONG!, Gridspace.

Cohort brief
Auto-generatedThe 252 portfolio companies with APIs in the catalog, backed by Bloomberg Beta, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Access Clarity | 21.5 | 22.3 | -0.8 | 252 |
| Developer Ergonomics | 15.6 | 17.9 | -2.3 | 252 |
| Contract Governance | 3.9 | 6.4 | -2.5 | 252 |
| Operational Transparency | 8.6 | 11.3 | -2.7 | 252 |
| Discoverability | 56.8 | 60.4 | -3.6 | 252 |
| Contract Quality | 9.8 | 17.5 | -7.7 | 252 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 14% | 16% | -2 |
| MCP server (first-party) | 9% | 7% | +2 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 6% | 9% | -3 |
| Security | 80% | 88% | -8 |
| Arazzo workflows | 1% | 2% | -1 |
| Governance rules | 6% | 13% | -7 |
mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
