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!;)

Clevertrack was founded with one clear ambition: to help businesses eliminate waste, reduce emissions, and make smarter operational decisions through connected machine and vehicle data. Every day, construction equipment, commercial vehicles, and industrial assets consume millions of liters of fuel while generating vast amounts of operational data. Yet much of that data remains fragmented and locked across manufacturers, systems, and spreadsheets - making it difficult, if not impossible, for businesses to gain the operational overview needed to take action. In just a few years, we've grown into a fast-moving technology company with one mission: making the world's fleets and heavy equipment more intelligent, efficient, and sustainable. Our team brings together expertise in software engineering, IoT, telematics, data analytics, and fleet operations - all driven by passion for solving real-world challenges. Our platform breaks down one of the industry's biggest barriers: fragmented data. Clevertrack collects real-time engine data, fuel consumption, location, and operational data across virtually every vehicle and equipment brand, bringing everything together in one unified platform. Instead of switching between manufacturer portals and disconnected systems, our customers gain one complete view of their entire fleet - turning complex data into actionable insights that reduce costs, improve utilization, prevent downtime, and accelerate sustainability initiatives. We're passionate about solving real-world challenges with technology and building products that make a measurable difference for our customers every single day. If you're excited about building scalable software, working with cutting-edge IoT technology, and helping shape the future of connected fleets, we'd love to have you on the journey.

Make It Good Again aims to break with the throw-away mentality, by making it easier and cheaper to get your broken items repaired. This is done through our website https://makeitgoodagain.dk/, with 3 easy steps: 1. The customer describes what is broken and put it up for the repairmen to give their bid on how much they can repair it for. 2. The repairmen participate in a reversed auction, to give the lowest bid on the repair. 3. The customer chooses their preferred offer. It doesn't have to be the cheapest. It can also be the most convenient, with the highest ratings or whatever other parameter is most important for the customer. We are passionate about our company and work hard to reach our potential.

NitroVolt is decarbonizing nitrogen-based fertilizer production and making the agricultural sector more resilient with a novel production process. Commercial ammonia production supports 40-50% of the agricultural industry as a nitrogen-based fertilizer. But current ammonia production is not sustainable, releasing over 1% of global greenhouse gas emissions during production facilities and further emissions during transportation to the end user, farmers. NitroVolt offers a local ammonia production solution that gives farmers the ability to produce their own nitrogen-based fertilizer. The only inputs required by NitroVolt’s container-sized systems are air, water, and electricity, enabling production of sustainable ammonia directly at farms. NitroVolt’s patented electrochemical Nitrolyzer unit can make ammonia on-demand with intermittent renewable energy sources. With their technology, NitroVolt aims to decarbonize nitrogen-based fertilizer production one farm at a time, cut the logistic costs of distributing fertilizer, and make the agricultural sector more resilient to external factors.
