We Outgrew the Name

You knew us as mFax — the cloud fax platform built for healthcare.

Over the years we added eSignatures, cloud storage, EHR integrations, a developer API, a proprietary delivery network, and Al-powered document processing. The name “Fax” no longer told the full story.

Documo is clean, forward-looking, and reflects everything we’ve become: a document interoperability platform purpose-built for regulated industries.
