Certifier gives organizations a single platform to create, issue, and manage verifiable digital certificates and badges at scale.
Key features include:
Certifier is trusted by 2,000+ global brands (Volvo, L'Orรฉal, Duolingo), organizations (Amazon, Salesforce, Mastercard), and universities (Stanford, UC Berkeley, Harvard).
BlockchainSign is a blockchain timestamping service for people holding documents they cannot hand over.
Conventional options all require custody: a copyright office wants a deposit copy, a notary wants to see the paper, an e-signature platform wants the file on its servers. BlockchainSign never receives the file at all. The document is hashed with SHA-256 in the user's own browser using the Web Crypto API, and only the resulting hash is written to the Ethereum blockchain.
The result is a certificate file recording the hash, the transaction and the timestamp. Because each certificate is its own Ethereum L1 transaction, with the payload hash readable as UTF-8 on a public block explorer, verification does not run through the vendor's portal: if BlockchainSign shut down, existing certificates would still verify.
There is no subscription and no cryptocurrency wallet involved. Certificates are bought as credits with a card and spent when needed. Credits are valid for 12 months; an issued certificate never expires.
Key points
What it does not do. A timestamp proves that a file existed in that exact form at that time โ existence and integrity. It does not prove authorship or ownership, and it is not a substitute for copyright registration. There is no API or integrations yet, and no eIDAS qualified timestamp.

Certifier's answer
Certifier's primary audience is organizations that need to issue verifiable certificates or badges automatically, tied to a real qualifying moment rather than created one at a time. That includes training and course providers, medical and CE/CPD issuers, associations and membership organizations, corporate L&D teams, higher education institutions, and organizations that certify partners or run workforce training programs. What connects them isn't industry so much as workflow: each needs issuance to be triggered by an event โ a course completion, a renewal, a form submission โ rather than handled manually.

Certifier's answer
Certifier combines a highly flexible visual builder (3,000+ templates, plus AI-assisted credential generation) with deep automation.
It connects to LMS platforms (Canvas, Moodle, LearnDash), CRMs (HubSpot, Salesforce, ActiveCampaign), spreadsheets, and forms. Zapier, Make, and Pipedream extend that to thousands of other apps, and issuance can trigger off nearly any real-world event: a course completing, a webinar ending, a CRM stage changing, or a bulk spreadsheet upload.
Every credential can be fully white-labeled, from the design itself to the page it lives on, so recipients see the issuing organization's own brand.
Altogether, that's a rare combination of design flexibility, workflow automation, and branding control, backed by a track record with 2,000+ organizations, from global brands to universities.
