kleen hub ApS

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.

Toco

Toco is on a mission to revolutionize the economic system by recognising our most valuable asset - our Home Planet. Through an innovative approach, Toco introduces a new digital currency backed by real-world climate projects that reduce and remove CO2 from the atmosphere and contribute to saving our Home Planet. With an easy-to-use payment app, Toco makes every transaction - from buying a plant-based burger to renting a city bike - a step forward towards solving climate change. OUR WHY: We are on a mission to solve climate change. We must protect our common resources that are vital to life on earth. We are uniting communities to make climate action simple. HOW: We have tested this concept in Stellenbosch, a small South African town, with 67% business adoption and 45% MoM Community growth. Individuals could live in a currency that values the environment instead of its destruction. We are now expanding in Zurich and Denmark. Toco is a new global currency backed by CO2 (Supported by https://www.thecarbonreserve.org/) Every toco represents one tonne of CO2 credibly mitigated from the atmosphere. We turn economic activity into climate action. CURRENTLY: This summer, Toco is launching in Copenhagen, offering a unique opportunity to join a climate-forward movement of talented individuals called the Custodians of the Common. Custodians are passionate about using their time and talents to protect the environment and solve the greatest challenge of our time - climate change. Custodians come together to create change NOW, driven by the realisation that time is running out for the planet’s finite resources and there is NO PLAN(ET) B! As a Custodian, you will be at the forefront of introducing Toco to Copenhagen, spreading the word, and onboarding businesses and individuals to join the movement and start using a currency that directly contributes to sustainable projects that remove or reduce carbon dioxide from the atmosphere, to combat climate change. Beyond the climate impact that each Custodian creates, Custodians volunteer their time and are financially rewarded based on the climate impact they create.

Responsibly

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 🤘

We start with ourselves: We have weekly runs, CrossFit in the park, healthy eating, sustainable sessions, and of course also the normal casual talks and loads of fun.
