Best company funding data providers
The company funding data landscape splits into two groups: self-serve providers you can measure head-to-head on identical company domains, and gated databases(Crunchbase, PitchBook, Harmonic) whose funding data can't be isolated or self-served. This page maps both — measured numbers for the first group (current leaders: Fiber on correct latest stage, Fiber on accuracy when present), and the honest reason each name in the second group isn't ranked.

The best funding data provider, by constraint
No single winner — the right provider depends on the failure mode you care about. Every leader is measured on the same 300 companies.
| Your constraint | Pick by | Current leader |
|---|---|---|

| Few wrong stage values when one is returned | highest accuracy when present | Fiber 84.2% |
| Most funding fields returned per company | highest field coverage | Fiber 89.1% |
| Resolve the most company domains | highest resolution rate | CompanyEnrich 97.7% |
| Lowest cost at public self-serve rates | cheapest for the cohort | Ocean.io $1.84 |

Crunchbase, PitchBook & the gated incumbents
The most-cited funding data names — but none exposes a self-serve funding API on identical terms, so their accuracy can't be scored here. Named, not ranked.
| Name | Why it's not in the head-to-head |
|---|---|
| Crunchbase | The funding search/enrichment API is gated to paid Business and Enterprise plans — the entry tiers don't expose it self-serve, so it can't be tested on identical self-serve terms. |
| PitchBook | Private-market intelligence sold as enterprise seats and data feeds; there is no self-serve public API to submit a domain and get structured funding back. |
| Harmonic | A startup-intelligence platform (strong at stealth and seed discovery). Access is sales-led rather than a self-serve company-to-funding enrichment endpoint on identical terms. |
| Tracxn / Dealroom / CB Insights | Research and market-intelligence platforms oriented to search and dashboards; funding data is contracted, not a single self-serve enrichment API scored per domain. |
Company funding data providers — common questions
Who are the best company funding data providers in 2026?
Among providers you can self-serve and measure head-to-head, Fiber leads on correct latest funding stage end to end (77.2% correct stage yield), Fiber on accuracy when a stage is returned (84.2%), and Ocean.io is cheapest at self-serve rates ($1.84 for the 300-company run). Crunchbase, PitchBook, and Harmonic are the names buyers compare, but their funding data is gated or enterprise-only — so their accuracy stays a claim, not a measured number.
Which funding data vendor is the most accurate?
Two measured answers: for the most correct latest-stage data overall, Fiber (77.2% correct stage yield); for the fewest wrong stages among the ones returned, Fiber (84.2% accuracy when present). Both are judged against source-verified funding events on the same 300 companies.
What's the difference between a funding data provider, API, and database?
Mostly packaging: a 'provider' or 'vendor' is the company selling the funding data; the 'API' is the self-serve endpoint you call with a company domain; a 'database' (Crunchbase, PitchBook) is a broader searchable product where funding is one view. The measurable layer is the self-serve API — domain in, structured latest-stage funding out — which is what this benchmark scores.
Why aren't Crunchbase, PitchBook, or Harmonic in the measured ranking?
Crunchbase's funding API is gated to paid Business/Enterprise plans, PitchBook has no self-serve API, and Harmonic is sales-led rather than a self-serve enrichment endpoint. The ranking covers providers testable on identical self-serve terms; the gated incumbents are named below, not ranked, because their accuracy can't be measured here.
