In your application, please send: 1. A link/video/screenshots of the existing CRM/EMR. 2. Which of the above features are already working today. 3. Whether we can have a live demo ASAP. 4. Current technology stack. 5. Current cloud/infrastructure setup. 6. HIPAA/security architecture and whether you support BAAs. 7. APIs/integrations currently available. 8. Whether source code is available. 9. Whether the system can be white-labeled. 10. Whether it supports multiple independent medical practices/organizations. 11. Your proposed licensing/acquisition/customization model. 12. How quickly your team can begin. Please do not apply with a proposal to build the entire system from scratch. We are specifically looking for an existing medical CRM/EMR foundation that we can evaluate immediately and customize rapidly. We would like to review demos ASAP.
