Behold

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.

Agoprene AS

Agoprene is a biotech startup based in Oslo and Copenhagen. Agoprene is developing furniture foam from biomass to help the furniture industry reduce their need for petrochemicals. ​ Globally, furniture foam, which is derived from petroleum, accounts for 105 million tonnes of CO2 emissions annually. One armchair for example, emits an average of 43 kg CO2e, almost half of which is due to furniture foam. ​ Agoprene's foam is completely free of petrochemicals. We believe finding planet-friendly alternatives isn’t a challenge; it’s an opportunity.

4i4

While our eyes is on the fourth industrial revolution, we want to be part of the energy revolution and help to reduce the CO2 footprint in every single workplace. we move towards greener workplace by a software solution on energy optimization of dynamic mechanical systems (DMS). Our target industry for now is ventilation systems so called as HVAC for office building. The product is a software solution that monitors and optimizes energy consumption of HVACs. But why HVACs? Ventilations are installed in almost all office and industrial buildings. Only in Denmark, 12 M m2 of area is dedicated to offices and buildings. This corresponds to a huge energy consumption by HVACs (about 40% of total electrical energy consumption of a building and funny enough buildings are responsible for almost half of energy consumption of Denmark in a year). Despite of HVACs simplicity from system point of view, they are very complicated and confusing for the HVAC owners. The energy consumption and waste energy is not clear. Therefore, energy optimization becomes a long shot. 4i4’s product is solving these issues and brings values for the HVAC owners by peace of mind and valuable insight on how to optimize the energy and save on CO2 emission.

NOON Ventures

NOON Ventures is a Copenhagen-based early-stage investor established in 2020. We invest in proven transformative technologies with the potential to significantly impact environmental or climate challenges. Our aim is to become the preferred partner for green entrepreneurs, and we do so by limiting our investments to few companies and working day-to-day with each of them – a fundamentally different approach than traditional early-stage investors. We believe that it takes much more than capital for companies to succeed - commercial experience, execution power, access to the right talent, network, and partners to name a few. We typically engage ourselves in all aspects of the business and do real work together with the founders applying the experience of our team, investors, and specialist advisors across mission-critical disciplines from strategy to customer introductions, and financing activities. NOON Ventures aspires to be true co-developers of businesses alongside the entrepreneurs, and we dedicate the time required to build lasting businesses.

RE-ZIP

What is RE-ZIP RE-ZIP is a circular packaging concept offering circular packaging to more or less all players in the ecommerce industry. By circulating and hence reusing rather than using single-use packaging (even recycled) we save CO2 even the first time a packaging is reused. It works likes this RE-ZIP delivers the packaging to webshops who offer the sustainable packing solution to their customers at check-out for a minor fee (paid back via reward voucher upon returning the packaging). Upon receipt of the goods the customer folds the RE-ZIP packaging to a return format and return it at a Drop Point. The packaging is returned to the RE-ZIP warehouse for cleaning and re-circulation to the webshops. The RE-ZIP packaging can be circulated up to 10 times, but more importantly the packaging will begin saving CO2 Within the first or second use – depending on the type. RE-ZIP has developed a state-of-the-art backend system supporting the above process and are currently operating in Denmark, UK and Poland. Hence working at RE-ZIP will offer you in-person colleagues in Denmark and remote colleagues in before mentioned countries and more to come. Working at RE-ZIP Working from the Danish RE-ZIP HQ you will find a bunch of nice new co-workers who appreciate to work from the office most days, because the energy we create together is important for us. That does not mean that you have to be here all day every day. You will have flexible working hours to accommodate your daily life. The atmosphere in the office is laid back and rather than working solo on projects and tasks we gather and combine our skills. Send us your application to come join us in our mission to change e-commerce packaging for good.

Klimate

We are devoted to accelerating the development and adoption of technologies that can help fight climate change by actively removing CO2 from the atmosphere. The challenge We are emitting 50 Gigatons of CO2 every year, and that needs to be reduced by at least 80%. However, that still leaves 10 Gigatons of CO2, and we need to get all the way to zero. Trees are great, but we need many more solutions as well if we are to get to zero. Currently, most of these are way too expensive (and limited in capacity) for companies to use. We've developed a platform that combines methods and makes it available to every company that wants to compensate their emissions. We work with cutting edge technologies, including Direct Air Capture, Bio char, Bio oil etc.

United Nations Youth Association(UNYA) Denmark

UNYA Copenhagen is a volunteer-driven youth organization dedicated to empowering young people to engage with global challenges through the lens of the United Nations’ values and the Sustainable Development Goals. We create an inclusive platform where students and young professionals can learn, collaborate, and take action on issues like climate change, social inequality, peacebuilding, and innovation. We are addressing a clear and growing problem i.e. the disconnect between youth and global institutions. Many young people in Denmark care deeply about sustainability and justice but find it difficult to access meaningful opportunities to participate in international dialogue or contribute to real-world impact. This gap leaves motivated individuals without a channel to apply their energy, creativity, and ideas, while institutions miss out on fresh perspectives and engagement from the very generation that will inherit the future. UNYA Copenhagen bridges this divide by turning global ideals into local action. We organize interactive events, workshops, and panel discussions that make complex global topics accessible and relevant. Our activities are co-created by volunteers from diverse academic and cultural backgrounds who bring their own insights to the table. Through collaboration with universities, NGOs, and public institutions, we connect youth directly with experts and decision-makers, fostering a sense of shared responsibility and agency. What makes UNYA Copenhagen unique is our grassroots approach. We are not just an organization — we are a community that thrives on collective energy and creativity. Every project is designed by young people for young people, ensuring authenticity, inclusivity, and long-term motivation. Our strength lies in our diversity and the genuine commitment of our volunteers, who bring the UN’s global mission to life in a way that feels personal and actionable. The motivation behind UNYA Copenhagen is simple: we believe that youth engagement should not be limited to classrooms or conferences but should become a lived experience. We started this initiative because we wanted to make international dialogue tangible, local, and inspiring. Our team members share a passion for learning, community-building, and positive change — values that drive us to dedicate our time to building something meaningful together. Today, UNYA Copenhagen continues to grow as a platform where ideas turn into impact. We are seeking motivated individuals who want to gain experience in leadership, communication, and project management while contributing to a global cause. By joining The Hub’s Community Program, we hope to reach more passionate volunteers who want to be part of a dynamic network that connects Copenhagen’s youth with the world.
