Trufo

Properties

category: provenance
maturity: growing
approach: Operates a C2PA Root Certificate Authority, listed on the official C2PA Trust List, issuing conformant C2PA/CAWG certificates; separately offers free C2PA metadata creation and invisible watermarking for creators, with paid enterprise pricing at scale.
access: freemium
owns: Provides content-provenance infrastructure: certificate issuance as a C2PA Trust List Root CA, plus a self-serve invisible-watermarking and C2PA-metadata-labeling service for images, video, and audio.
distinctFrom: Unlike c2pa (the standard itself, which Trufo implements) or truepic (a hardware-capture-focused C2PA certificate authority built for insurance/lending/journalism customers), Trufo is a Trust List Root CA that also runs a free, self-serve consumer watermarking and labeling product rather than only a capture-side enterprise platform.
source: C2PA Trust List (c2pa-org/conformance-public, GitHub)
notes: Root CA status verified directly against the C2PA organization's own trust-list file, which also lists Google, SSL.com, DigiCert, Adobe, and others as fellow trusted CAs. Separately, Trufo's own blog states its freemium product model: 'Basic information fields, including common copyright terms, are free... [invisible watermarking is] free, with 100 daily credits; typical image = 1 credit... Enterprise solutions starting at one cent per image' (medium.com/trufo/what-is-trufo-e70ba3fb8cbe). Claims of an MIT-licensed open-source SDK ('OpenProv') appear in secondary coverage but could not be confirmed via a direct quote from Trufo's own site (a JS-rendered SPA that WebFetch could not extract text from); omitted from approach/owns as unverified. Company founding (reported as late 2023) predates this run's 2026-07-11 window; flagged as an untracked gap-fill, not a new launch.
