THE PROBLEM Searching second-hand online requires navigating hundreds of platforms and incomplete listings, forcing shoppers to do the heavy lifting of finding and comparing relevant items. The decentralized and the fragmented second-hand market creates a time-consuming and frustrating experience for shoppers to locate desired items among incomplete listings and outdated platforms. THE SOLUTION Koral aggregates millions of second-hand listings into one searchable platform with categorized, indexed data to create a one-stop solution. This eliminates tedious searches across individual platforms, making shopping second-hand is easier by improving discoverability and streamlining the process of finding desired items online.

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!;)

The uMover® is a smart and usability-focused 3-wheel electrical vehicle for transporting people over shorter indoor and outdoor distances (0,5-5 km). It has been developed by us, DTU spinout CJ Company IVS, whom have built the uMover® upon a future mobility concept proposed by Continental AG (CAG). The uMover® targets employees who need to travel frequently within shorter distances, enabling them to become more efficient at work by easing their way of travel and reducing their travel time substantially. The uMover® will be a superior work-environment travel solution, as it – due to its smart design – offers the flexible advantages of walking, but with the similar speed and ease as driving a car or a bike. Drawbacks of the solutions in the market today are high prices, space requirements (especially for cars), no compliance with traffic regulations and laws and poor safety control (limiting the indoor application possibilities). Through cooperation with DTU and CAG we have been able to complete a full proof-of-concept and develop several of the unique mechanical components and are now in the detailing phase of the mechanical and electrical construction for a scale-up of the uMover®.
