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 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!

Our planet is overheating, biodiversity is reducing rapidly, and natural resources are being depleted. With 40% of global energy-related CO2 emissions and 30% of global landfill waste, construction plays a significant role in our planetary crisis and is by far the most polluting sector. We need to do things differently. Stykka takes you on a journey toward a future where the construction industry is part of the solution rather than the problem. We’ve set out to develop scalable solutions that enable like-minded developers and investors to build more sustainable, efficient and profitable. With Stykka we enable forward-thinking developers to build sustainably and be part of the solution rather than the problem. We use cutting edge technology like 3D scanning, digital fabrication, and distributed manufacturing to create new experiences and amazing, sustainable products for an array of clients.   With Stykka we aim to leave a positive impact on our planet and solve one of the biggest problems of our time, and we want you to be part of this journey.

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.
