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!;)

We turn life science and deep tech ideas into commercially successful companies. We serve both as a consultancy and as a venture builder. At Marigold Innovation, we build bridges between research and business, science and product, researchers and investors. Most scientists prefer to stay where they add the most value, namely as highly skilled scientists and inventors who understand the translational process at an intellectual level, without the deep insight and experience in how to execute accordingly. ​We want to ensure that the skilled scientists focus on what they excel in – doing science and inventing stuff! ​ Marigold Innovation closes the gap by bringing the competences required to complement the scientific team. In this way we ensure that all necessary skills are in place at the needed timepoint and at the right level to secure the optimal development path from academia to a commercially viable company.
