CoPatient
CoPatient is a Connecticut-based healthcare startup that helps consumers reduce medical bills and resolve related problems.
Vilmate worked with the company’s founding partners to develop its web application.
The challenge
CoPatient wanted to automate interactions between healthcare consumers, consumer advocates, and medical billing experts.
The application had to help users understand their medical bills, determine whether a case could benefit from review or negotiation, and reduce the time and costs involved in dealing with medical institutions.
The product also had to support different account options, document submission, and online communication between all parties.



Our approach
Vilmate worked closely with CoPatient’s founding partners throughout the development of the application.
Work under client management
Vilmate assembled a team of four specialists: two full-stack developers, one web developer, and one QA engineer. During the two-year development period, they worked under the client’s direct management.
Meet data security requirements
The team accounted for stringent US legal requirements governing the secure storage of user data and documents.
Account for mobile use
More than 60% of user requests originated from mobile devices—a fact that had to be considered throughout development.

The solution
Vilmate’s team helped turn CoPatient’s concept into a working web-based application.
Account and document management
Users can choose between free and premium accounts and upload medical bills and related documents through the platform.
Bill review and expert communication
The application helps users identify bills that may benefit from review or negotiation and discuss their situation online with consumer advocates and medical billing experts.
Launch and continued development
The requested functionality was delivered on time and within budget. The system went live and entered active commercial use, while the team continued expanding the application in line with the client’s evolving business vision and plans.
