Kleen Hub is a Copenhagen-based circular tech company building Tap & Reuse™ — a frictionless reuse system that makes reusable packaging work at scale. Our platform combines simple hardware with a lightweight software layer to enable fast, reliable reuse without the usual barriers: no app, no user registration, and no deposit handling required. We help venues and operators (cafés, campuses, stadiums, airports, corporate sites and more) replace single-use packaging with reusable cups and containers through an operationally simple setup. Tap & Reuse™ supports multiple return flows (smart return stations, return bins, handheld scanning and washing-site verification), delivers high return rates in closed and semi-closed environments, and provides clear reporting for operations and ESG. Kleen Hub works with leading partners and distributors across Europe and has deployed systems in high-volume environments, proving that reuse can be convenient for users and manageable for staff. Our mission is to remove friction from reuse and accelerate the transition away from single-use packaging — by making reuse as easy as tapping a card.

Responsibly is a sustainability tech start-up with vision of making every purchase in the world responsible 🌍 There's no bigger problem out there than the climate, and procurement represents a big part of the solution - when purchase decisions are made on the background of responsible data like CO2 footprint, suppliers have a huge incentive to change. However, procurement is becoming overloaded with complexity. Different frameworks, different data sources, different coverage, making it difficult to make purchase decisions to improve your responsibility profile and scope 3 emissions. At Responsibly, we're trying to solve this issue by using leading technologies and data science, to build a supplier data platform that makes it easier to source responsibly. We're founded by two serial entrepreneurs with previous successes like Dixa and Ofload, and have received pre-seed funding from some of Europe's top VCs and angels. We're now building a top-tier team to tackle this big thing called climate, and have fun while we're doing it 🤘

Behold helps animals change people. Our technology turns everyday wildlife encounters into moments of discovery. It meets people where they are, whether at home, on their devices, or in their communities. It shifts how they see nature and their role in it. It is entertainment with a purpose, designed to inspire and influence behaviour in subtle but meaningful ways. But we are not just here to tell stories. We are building a network of thousands of garden cameras, creating the largest database of residential wildlife sightings. A powerful tool for conservation, citizen science, and understanding the changing natural world. Our first product, Behold Cam-1, became a massive success on Kickstarter – hitting its funding goal in under 2 hours, and raising almost $400k in pre-orders. We're now bringing that product to market. It’s an opportunity to join at the earliest stages—with all the challenges and rewards that come with it.

Our Mission: Normative is here to make known and reduce the sustainability impact of all economic activities on the planet. We provide science-based carbon accounting software and tailored advice from net zero experts, enabling companies to reduce their carbon footprints. Our Story: Normative is rooted in climate research. In 2013, co-founder Kristian Rönn was working at Oxford University, simulating the consequences of climate change. The results showed that global warming would cause extreme human suffering, motivating Kristian to leave academia and take action. He joined forces with Adam Wamai Egesa and Robin Undall-Behrend, and in 2014 the world’s first carbon accounting engine was born to help humanity achieve net zero emissions and reverse the trajectory of climate change. We now have offices in Stockholm, Copenhagen, and London, and are actively hiring talent to join the mission. Today, companies from around the world trust our carbon accounting engine to help them reduce their carbon footprint. We partner with leading climate change organisations including the UN, to deliver actionable sustainability intelligence and have received a grant from Google. We are backed by some of the world’s most significant climate investors, and are the official software provider for the UN-backed SME Climate Hub initiative through which thousands of small businesses have committed to net zero. Our Team: We are a global team working to solve a global problem. We’re headquartered in Stockholm, with offices in Copenhagen and London as well as remote team members located all over the world. We have spoken at the World Economic Forum, consulted the European Commission, and worked with the United Nations to develop a new standard for emissions accounting. We come from many walks of life, but we’re united in one mission: to help humanity achieve net zero emissions. Every employee at Normative plays a valuable role in reducing business carbon emissions.

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.

Our carbon emissions are still increasing, and the evidence for dramatic climate change is all around. We want to do our part in solving it. In Europe, 12% of our carbon emissions come from heating our homes - just as much as using our cars. Getting those emissions to zero will be a gargantuan task: retrofitting 90 million buildings across many countries is a hard problem. Lun’s mission is to decarbonise homes faster, by building an operating system for tradespeople in the European energy renovation industry. Our first task is to make heat pump installations an absolute no-brainer for plumbers and electricians.
