Medusa was founded in 2021 by Sebastian Rindom and Oliver Juhl in Copenhagen. They’d spent years working with Shopify and other platforms and kept hitting walls when clients needed custom checkout flows, unusual pricing models, or non-standard fulfillment logic. They built Medusa to give developers the building blocks without the constraints.
The platform is written in Node.js with TypeScript and follows a modular architecture. Every piece — payments, fulfillment, notifications, inventory — is a self-contained module that can be swapped, extended, or replaced. The API is RESTful, and there’s a JavaScript SDK for frontend integrations.
Medusa raised $9 million in seed funding in 2022, backed by Felicis Ventures, Y Combinator, and other investors. The open-source repository crossed 20,000 GitHub stars and attracted a community of thousands of contributors building plugins and integrations.
Medusa 2.0, released in late 2024, represented a ground-up rewrite. It introduced a new data modeling layer, improved workflow engine, and a built-in admin dashboard. The rewrite focused on making complex commerce logic — like marketplace setups, B2B pricing, and subscription models — achievable without hacks.
The platform positions itself against Shopify for teams that need more customization, and against commercetools for teams that want open source and lower costs. The company employs around 60 people across Copenhagen and remote locations.
