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.

Elysium Energy is building the AI-enabled platform that accelerates energy decentralization by unifying distributed energy resource (DER) projects with developers, capital, and expertise in a marketplace ecosystem. We're eliminating the fragmentation that kills 90% of DER projects by creating a single source of truth across the entire project lifecycle—from concept to operation. We have 5 active design partners across US, UK, and Indonesia, 2 pilot projects converting to paid customers, and have raised $150K SAFE from ERA plus $100K in non-dilutive grants. Our MVP is live and demonstrating 18% CAPEX reduction and 20% OPEX savings for energy projects. We're addressing a $16B software opportunity in the rapidly growing DER market.

We're making innovations for assessing marine biodiversity, essentially building underwater cameras and using AI to count fish. We're in the midst of a biodiversity crisis, the wildlife population has shrunk by 73% in the last 50 years alone, and it is especially bad in marine environments. At Anemo we monitor the effect of man-made structures on the marine environment to help our clients comply, quantify impacts, and continually improve nature-positive outcomes.

Freight forwarders are being asked for greener transport, but most still do not have a simple way to sell it. Refine plugs into the forwarder’s operation and turns shipment data into a ready-to-sell low carbon offer. We bring pricing, sourcing, customer acceptance and documentation into one end to end workflow. The idea is simple: help freight forwarders build a new business line, earn more on every customer relationship and become the green partner their customers actually want to work with.

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.

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 🤘

At Hybird, we operate at the intersection of hardware and software where we are bringing the electrical panel online and transforming it into a data platform. This gives us an opportunity to improve tooling for installers and facility managers, as well as surface actionable insights to a variety of stakeholders. The objective for us is to increase our understanding of power consumption and use that to help curb consumption.

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.
