Startups 2025

circuly knows the pain points of scaling subscription models - after all, our founder began developing circuly in 2018 as a retailer who found no fitting SaaS to solve them. Since then, circuly’s circular-economy solution has matured to cater to physical product, consumable and digital subscriptions. circuly’s solution & team now serve ±50 brands/retailers (e.g. Riese & Müller, StrollMe, swing2sleep, bugaboo) in 17 countries on 5 continents and our USP’s have us poised to dominate the e-commerce subscription sector.

Problem: Changing consumers, stricter regulations and tough economies increasingly demand that retailers offer “circular economy” solutions like subscribing to products, but to manage and scale this model, retailers need a mature SaaS that masters subscriptions of physical products.

Solution: While most SaaS solutions which focus on digital subscriptions or subscription financing, circuly specializes in the management and scaling of physical product subscriptions.
