We are passionate reinventing how homeowners and skilled builders find each other. In the past, if you needed building work done on your home, you would have to rely on word-of-mouth or hope that someone you know could recommend a good builder. 3byggetilbud.dk changed all that by creating a marketplace where homeowners can post their jobs and then the platform matches the best three builders for that specific job. This means that you can be sure to find a builder who is not only reputable but also has the skills and experience to do the job well. Our commitment to innovation has made us the market leader for Danish homeowners and builders alike.

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!;)

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.
