Unbelievable Labs

Based in Aarhus, Denmark, we are a Venture Lab for hard things, worth doing. Contrary to what many may think, the technological progress has stagnated for nearly four decades. Enabling and fundamental innovations such as the practical use of electricity, the telecommunications infrastructure, automatic computing, automotive transportation, heavier than air flight, genomics, and many other examples, all arose prior to the 1970s. What we have witnessed as progress within a generation is largely the application of these technologies in increasingly refined solutions. The latest wave of “softwaretization”, have increased operational efficiencies in multiple industries but also offset culturally and personal demand for tangible products and interactions, by web and app-based experiences. Our core thesis revolves around overcoming challenges in commercialization of scientific breakthroughs by providing the facility between scientists and entrepreneurs. We extend the conventional 10-year venture capital horizon, allowing for the maturation of technologies and customer demand. We focus specifically the hard sciences: physics, chemistry and their derived engineering disciplines. The markets and industries we work with are: - Military and Defense - Energy systems - Sustainable Resource Extraction - Access to space and ocean - Autonomous systems - AI for physical applications - Meta-materials and composites. We have great hopes for the future, and dare to bring it about. Come join us!

Cirqle

Plastic waste and single-use packaging is one of the great unsolved problems for our planet. In Denmark, we produce 844KG of household waste annually per person. Most of this packaging is used for food and beverage products and it is an increasingly large environmental challenge. At Cirqle we are driven by our mission to make single-use a thing of the past and make reuse packaging the norm. Reusing packaging reduces the impact, and greatly minimizes the natural resource use of packaging. With our pioneering reuse packaging service and technology platform, we make reuse a reality for companies in the food and beverage industry. We are already breaking new ground with our meal-kit service, but the sky's the limit when it comes to reuse packaging. With partners we cover the full supply chain from packaging production and software development to sanitation and logistics making sustainability the easy choice for our customers.

HEMBOO

We are HEMBOO: an early stage start-up with the vision of making low emissions, renewable materials the norm in construction. Besides fossil fuels, the production of concrete is the worst emitter of CO2 in the world. However it is the most used material within the construction sector. But not for long: climate legislation is about to make concrete a whole lot more expensive, by introducing a CO2 TAX. This leaves the construction companies with a problem as there is no valid sustainable alternative they can use. HEMBOO offers an easy solution: prefabricated walls for new construction made of hemp and bamboo with a reduction of 80% CO2 emitted compared to the traditionally used concrete walls. BUT the construction industry is very conservative and risk-averse. Therefore getting to market is a long journey. We built our first prototype are now preparing for the second one and are gathering data on the needs of our customers. Our aim is to provide a solution similar enough in prefabrication and installation methods, to make the transition from concrete fast and easy. Our element is designed for large scaled production so that we can have the largest impact. Recently we have received a total of 520.000 dkk in soft funding for product development and are participating in multiple startup support programs so it is full speed ahead! The team behind it all: We are a diverse team of three, Elsa Maria Iuliano, Helena Brandt Rejndrup and Michael Hallam. Helena and Elsa graduated as architectural engineers from DTU while Michael is finishing up his studies in design and entrepreneurship. We started HEMBOO because we are all very passionate about making an environmental impact. As a team we have a lot fun together, while still being productive. We emphasize a friendly environment where we help each other even though everyone has individual responsibilities. Currently looking to expand and we want you to be a part of it! Reach out if you are interested in getting on board. We are particularly interested in commercial, communication and financial competencies. Based in our joint office spaces in the center of Copenhagen and at CBS in Frederiksberg. And yes they do they do have Friday bars :-) Feel free to contact us with any questions!

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.

Swan Neck Bio

Swan Neck Bio partners with food and biotech companies of any size to scale, commercialize, and deploy their microorganisms. Our vision is a world where there are no constraints to progress for the biosolutions urgently needed by a growing population. Today, food and biotech companies with promising solutions looking to scale are held back by a slow testing phase and huge capital outlays. These unnecessary constraints cause too many businesses to fail before their time. We partner with you to help you trial, validate, and scale your microorganism from lab to 1,000L. This dramatically derisks your scaling process and accelerates your time-to-market. And its 10-100 times cheaper than existing solutions.
