Mercur - modern marketplace platform without limits.

Online marketplaces are outgrowing traditional eCommerce, yet the tools to build them remain fundamentally flawed. Companies either risk creating homegrown solutions or settle for platforms that limit their vision and cut into their profits.

Every marketplace needs unique features to compete effectively - from custom pricing models to specialized vendor onboarding flows. Yet current platforms make adding these features painfully slow and expensive.

After successfully building several marketplaces from scratch at Rigby, we saw firsthand how existing solutions force companies to choose between costly custom builds or profit-draining platforms.

Most companies lose precious time and resources trying to adapt rigid platforms to their unique business models. They struggle with outdated technology stacks, limited customization options, and mounting technical debt. To succeed, they often need to maintain large development teams or settle for generic solutions that don't quite fit their vision.

That's why we created Mercur - the first truly limitless marketplace platform.

Unlike SaaS platforms that charge per transaction, Mercur gives businesses full ownership with no transaction fees and no restrictions. It serves as the foundation for your custom marketplace, providing all the building blocks you need while maintaining endless possibilities to expand.

Built on MedusaJS, the most popular open source commerce platform, Mercur delivers the simplicity of SaaS with the freedom of open source. Create high-quality experiences for both shoppers and vendors while maintaining complete control over your marketplace's future.

Who is Mercur for?

• Companies that look for the creation of a standalone B2C or B2B marketplace for their brand. 
• For retailers that are looking for an extension of their current eCommerce store.
• For complex use cases like renting, SaaS marketplace or online goods.

We believe that in the future, when you want to build a marketplace, you shouldn't have to choose between ownership and ease of use.
