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!;)

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.

At North ESG, we’re building the AI-powered ESG accounting software for SMEs. 99% of all companies in Europe are small and medium-sized enterprises. They drive our economy - but when it comes to sustainability, they are underserved. ESG reporting is complex, time-consuming, and an administrative hassle. We believe the future of ESG should be about growth - not admin. Our mission is to free up time and strengthen the ESG profile of SMEs as a commercial advantage, so they can stay competitive, win more business, and meet rising demands from customers, regulators, and investors. Our platform automates the entire ESG reporting process using AI - from data collection to emissions calculations and EU-aligned reporting. It integrates with ERP systems and leverages both public and private data sources to generate tailored, commercially viable ESG reports. We’ve already gained strong market traction across industries in Denmark. And with ESG requirements increasingly cascading down from large corporates and financial institutions, we’re solving a growing pain for millions of SMEs across Europe.
