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.

Documo was the only solution that understood our needs and provided excellent support. We’re a small team, so having reliable customer service matters greatly. From the first call to ongoing support, they've been amazing, making Documo the right choice for us.

Documo stood out due to their well-documented API and HIPAA compliance, which fit perfectly with our needs. Compared to alternatives like Faxpipe, Documo's features and documentation made them the better choice, especially for our team managing sensitive information and building new applications.

Documo’s all-in-one solution simplified our process immensely. We no longer have to print documents for signing, which has cut down turnaround time significantly. The integration with our EMR system was seamless, allowing faxes and e-signatures all in one place.
