A market total is a methodology, not a fact

The record

Three organisations that publish venture-funding totals describe, in their own methodology pages, three different things they are counting. PitchBook's report methodologies page, retrieved 16 September 2026, explains that because information often does not become available until well after a transaction takes place, PitchBook estimates the deals and exits still to be reported, and states that both the original reported figure and the estimated figure are provided for the reader's reference. Crunchbase's methodology page counts angel through Series C+ rounds while excluding private equity, secondary transactions, debt and grants, and states outright that no database of private companies or their funding rounds is 100% complete or up to date, not even Crunchbase. Dealroom's data page describes a pipeline of public information harvesting, data engineering, AI processing and manual verification, combined with data partnerships with more than 100 governments. None of the three pages describes the other two providers' figures, and none claims to produce a single market total.

What the sources establish

The pages establish that a venture total is the output of a counting rule, applied to a sourcing process, at a point in time. PitchBook's rule adds a modelled adjustment for late reporting on top of what has actually been filed or disclosed, and keeps the reported and modelled numbers visibly separate rather than merging them into one figure. Crunchbase's rule depends on voluntary submissions and public sourcing, and notes that funding at the earliest stages lags and rises after a quarter closes. Dealroom's rule leans on machine processing checked by people, plus government data unavailable to competitors. The three pages describe three separate measurement systems, not three attempts at one measurement.

Scope and revision

Scope differs by what is included before a total is ever calculated: Crunchbase's stated exclusions are not the same exclusions PitchBook or Dealroom apply, and none of the three pages states that its scope matches another's. Revision differs by mechanism: PitchBook's is an explicit statistical estimate reconciled against later filings; Crunchbase's is passive, arriving as new disclosures are entered; Dealroom's pipeline updates continuously through alerts and re-verification rather than on a fixed quarterly cycle. A total built today from any one source will not equal the same period's total pulled from that source in a year, because the estimate step or the disclosure count moves.

The decision in front of you

This is an editorial framework, not a ranking of providers. Before repeating a market total, name the provider, the period it covers, what it counted in and out, and whether the figure is a first pass or a reconciled one. A total with no provider attached cannot be checked against anything.

• Which provider's rule produced this number, and does its methodology page say what it excludes?
• Is this a first-reported figure or one already adjusted for late disclosures?
• Would the same period, pulled from a different provider, plausibly show a different total for a documented reason?

A market total is not a fact waiting to be reported; it is a methodology's output, and the methodology is the part worth keeping attached to the number.
