Remexis is a cutting-edge, AI-powered platform providing evidence-based natural medicine guidance for healthcare professionals. To support its evolution into an enterprise-grade solution, we architected and implemented a comprehensive B2B billing and organization management subsystem. This infrastructure enables clinics and medical teams to manage seats, track real-time AI usage, and handle complex subscription lifecycles. By integrating a resilient Stripe-based event pipeline and a granular auditing ecosystem, we empowered Remexis to scale from a single-user tool to a multi-tenant platform ready for global healthcare teams.
