Value proposition

Products and solutions
Automated Patient Referrals, Medical Document Processing (including faxes and forms), Payment Posting Automation, Medical Record Management, Claims Auditing
Unique value
Tennr's primary innovation is its specialized focus on automating messy, unstructured healthcare workflows that still rely on outdated technology like faxes. It has developed a proprietary AI model specifically for this purpose.
Target customer
Healthcare practices, hospitals, and clinics of all sizes.
Industries served
Healthcare
Technology advantage
The core technological advantage is RaeLM™, a proprietary 7-billion parameter language model trained on over 3 million medical documents. This allows for high accuracy in interpreting complex and varied healthcare paperwork, including handwritten notes and checkboxes, which general-purpose AI models often fail to process correctly.
How they differentiate
Tennr differentiates itself by focusing deeply on automating specific, document-intensive back-office and administrative tasks (like fax processing) rather than providing a broad platform for provider search or general hospital operations. Its specialized AI is tailored for high accuracy on unstructured medical data.
