Amsterdam Circular is a cost-free chain accelerator program developed in collaboration with the Municipality of Amsterdam. It supports early-stage circular ventures by helping them bridge the funding gap, connecting them with both private and public investors, and exploring chain financing opportunities.
The fifth edition officially kicked off on 27 March and focuses on circular consumer products. Below, you can discover the ten startups participating in this year’s program.
BOAS
Vintage clothing shop and product resales platform
BOAS solves fashion's overstock crisis. With EU law now banning the destruction of unsold inventory, brands need a profitable alternative to dumping — but traditional resale has always been too slow and costly to work at scale. BOAS changes that by combining AI, robotics, and social workers to process each item in under one minute at ~€2, making circular resale economically viable for the first time.
Booomtag
Digital product passports for sports equipment
Booomtag solves the identity gap in sports products. Once a product leaves the factory, brands lose all visibility into its journey - making repair, resale, recycling, and regulatory compliance nearly impossible to manage. Booomtag gives every product a persistent digital identity that travels with it from manufacture to end-of-life, enabling brands to stay connected, meet compliance requirements, and drive circularity long after the point of sale.
Cupxchange
Reusable cup-as-a-service for companies and events
Cupxchange tackles one of the most wasteful throwaway habits in daily life. Over 4 billion disposable cups are discarded every year, each used for just 8 minutes before becoming waste. Cupxchange replaces them with a simple, reusable-cup rental and cleaning service, giving companies, events, and consumers a practical, zero-waste alternative.
Ontspulknul
Social enterprise organising Declutter Days
Ontspulknul removes the friction from decluttering. Vast amounts of unused items sit idle in homes, not because people don't care, but because donating them is inconvenient. Ontspulknul makes it effortless through neighbourhood declutter days, home assistance, and pickup services, getting unwanted items out of homes and into the hands of local charities and circular entrepreneurs.
Packbags
Modular bags designed for repair and reassembly
Packbags rethinks the bag from the ground up. Textiles are built to last but not to be fixed, so when something breaks, people throw it away, contributing to 92 million tonnes of textile waste every year. Packbags offers a modular bag system where straps, pouches, and components can be swapped or replaced, so nothing needs to be discarded just because one part wears out.
Rebottled
Iconic glassware made from discarded wine bottles
Rebottled skips the recycling process entirely. While glass can technically be recycled, it still requires energy-intensive melting and remanufacturing. Rebottled takes discarded wine bottles and upcycles them directly into premium design products - no melting, no reprocessing, just waste transformed into something worth buying.
Renewaball
Circular tennis and paddleball system
Renewaball closes the loop on sports balls. Over 600 million tennis and padel balls are thrown away every year, breaking down into microplastics with no viable recycling solution. Renewaball collects used balls, recycles them into clean rubber and wool felt, and manufactures new ITF- and IPF-compliant balls, delivering a fully circular, B Corp-certified system for clubs, cities, and federations that reduces CO₂ by 29%.
RepareerSimpel
Discovery platform for gadget repair shops
RepareerSimpel fixes the repair market. Europeans throw away €5.1 billion worth of repairable products every year - not because repair is impossible, but because finding a trustworthy, fairly priced repair shop is too hard. RepareerSimpel connects consumers to vetted local repairers through a transparent digital platform with clear pricing, easy comparisons, and quality guarantees.
Swapped
Furniture swapping platform
Swapped stops furniture from going straight to incineration. Today, bulky household items are loaded into compactor trucks and destroyed before anyone checks whether they could be reused or recycled. Swapped uses AI to assess each item from a single photo before collection, automatically routing it to the best outcome - reuse, repair, recycling, or, only as a last resort, incineration.
The Swap Club
Circular clothing swaps and pop-up shops
The Swap Club makes reuse rewarding. Usable items are discarded every day because existing resale platforms are slow, clunky, and fail to keep people engaged. The Swap Club is a points-based urban reuse platform where items are scanned, graded, and converted into points, letting people exchange goods through a digital wallet via pop-up shops and a mobile app.
