Fundz

Fundz is an event-first business intelligence platform, founded 2015, tracking 200,000+ companies and surfacing funding rounds, executive changes, M&A activity, SEC filings (8-K, 10-K, 10-Q, Form D) and website modifications in real time. Rather than storing millions of static records it focuses on companies showing active signals, and scores them against each user's criteria. The API exposes company profiles, fundings, SEC filings and fund formations from api.fundz.net with an API key in the Authorization header. It sits in the same category as Harmonic and Crunchbase, and competes explicitly on access: an API key is free and issued instantly with no card and no sales call, and pricing is published rather than quoted. Fundz also ships an MCP server listed on the official Model Context Protocol registry, and publishes an llms.txt.

Fundz publishes 6 APIs on the APIs.io network, including Acquisitions API, Agreements API, Crowdfundings API, and 3 more. Tagged areas include Business Intelligence, Funding, Private Markets, Mergers and Acquisitions, and SEC Filings.

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

Fundz’s developer surface includes documentation, pricing, signup flow, authentication, sandbox, API reference, getting-started guide, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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/fundz: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

      and /.well-known/openapi.json at api.fundz.net, on app.fundz.net, and in the fundzwatch-mcp repository. No spec was
      modelled on their behalf; the gap was recorded instead. The spec was NOT hidden from a discoverable path — it lives
      in a separate repository nothing at api.fundz.net or app.fundz.net links to, and the founder supplied the URL directly
      on 2026-08-06.
