Every published specification, schema, and protocol that VC Deal Flow Signal implements end-to-end. Each entry links to the canonical spec and to the surface on this site that exposes it. We do not declare conformance to standards we do not implement.
The one belief this page asks for: a standard you can’t independently check is just a badge. Every spec below links to the canonical source and to the exact surface here that implements it — so your engineer can confirm it without taking our word.
Why this page exists. E-E-A-T signals are not just bylines and headshots. They are verifiable, machine-checkable conformance to the standards that the web of data is built on. Every row below is a public spec you can validate this site against — open the spec URL, hit the "applied at" endpoint, and check the output.
For a non-technical buyer,the takeaway is simpler: you don't have to take our word for anything. Every claim on this site resolves to a public spec or a public dataset your firm's engineer can validate in an afternoon — and you can hand this page to them without reading a line of it yourself.

The accountability policies a publisher is expected to state plainly. These are the human-readable source for the publishingPrinciples, noBylinesPolicy, correctionsPolicy, ownershipFundingInfo, verificationFactCheckingPolicy, unnamedSourcesPolicy, and actionableFeedbackPolicy properties declared in this site's Organization JSON-LD.
Editorial work is published under the pseudonymous byline The Data Nerd by deliberate policy, not omission. The methodology is the protagonist; the operator stays anonymous on purpose. The identity is nonetheless persistent and accountable: one ORCID iD, one author profile, and a published, DOI-bearing methodology paper stand behind every claim. No claim depends on the author's identity — each is traceable to the public dataset.
Independently operated and self-funded by subscription and dataset revenue — not affiliated with, owned by, or funded by any incumbent VC platform, fund, or data vendor. Full ownership and funding disclosure is published in the annual Transparency Report.
Every signal is derived from public GitHub activity. We use no private, scraped-behind-login, or unnamed-source data, and we do not pay for tips. There are no anonymous sources to protect because there are none — the inputs are public and the transformation is documented in the methodology. Conflicts of interest (any position in a covered company) are disclosed at point of coverage.
Spotted an error? Email signal@gitdealflow.com or open a public GitHub issue. Verification-driven fact-checking is documented in the methodology, and every accepted correction is logged publicly, with date and rationale, in the corrections log.
You came here to vet us — fair. If it checks out, the calmest way in is the free Sunday digest: five accelerating startups a week, no card, one-click unsubscribe, and you never have to read a line of code. Nothing on this site auto-charges, and the methodology behind every pick is public.
