We`ve been organising Startup Weekends in Copenhagen for 4 years, educating and inspiring hundreds of people to become entrepreneurs. We were lucky to see it from the first row how #CPHSW helped people get into the entrepreneur mindset and to try new challenges. We always believed that one of strongest forces were the network of people you created during those crazy weekends. This is why we created Startup Weekend Mega: The biggest Startup Weekend ever organised in Europe.  We´re an awesome group of volunteers coming from a wide variety of backgrounds. All of us have their own stories about how we ended up joining the #CPHSW family.  We are proud that we`re 100% voluntarily run organisation and that we created a culture where everybody feels safe to experiment and make their own decisions. And we`re always there to support each other outside Startup Weekends.  We think being part of the organiser family is an excellent opportunity to try out craziest ideas in your field. A playground where we can have a lot of fun and learn a ton. After years of experimentation now we`re organising our biggest event, Startup Weekend Mega, and we would like to involve new people on this journey. If this makes you excited then please feel free to reach out copenhagen@startupweekend.org  or directly at the job posts. Fun guaranteed!;)

RiskFinder helps the companies that keep heat, water and power running stay ready when something goes wrong. Our customers are utilities and critical infrastructure operators. Every year they face more cyber threats, extreme weather, supply chain failures and new rules. Most of them already have emergency plans and risk assessments. But the information sits in long documents, spreadsheets and people's heads. That is exactly where it is useless in a real crisis. We turn it into something teams can use under pressure: clear action cards, live risk tracking, exercise planning, supplier and asset overviews, and the proof that they are ready. This is not a tool for auditors. It is for the person on shift when a plant goes down at 3am, who has to make the call and keep the city warm. Those are the high-stakes moments we build for. When it counts, the work has to hold. We are early. RiskFinder is a small operation working with serious customers on hard problems. There is no narrow lane to stay in. You will see how the whole thing fits together, from talking to the people who run a plant to shipping the feature that helps them. If you want your work to land on something real, with people who genuinely need it, this is a good place to spend your time.

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.

ESEBA, a deep tech startup from DTU, transforms low-quality textile waste into MDF boards without binders or formaldehyde. We offer a sustainable, non-toxic alternative to traditional wood-based panels. Textile waste is a massive and growing problem in Europe – less than 1% is recycled into new products, and most ends up incinerated. At the same time, formaldehyde regulations are tightening, and deforestation pressures are increasing demand for alternatives to virgin wood. ESEBA’s mission is to enable local, circular board production through a scalable, plug-and-produce production line for furniture manufacturers.
