Plastic waste and single-use packaging is one of the great unsolved problems for our planet. In Denmark, we produce 844KG of household waste annually per person. Most of this packaging is used for food and beverage products and it is an increasingly large environmental challenge. At Cirqle we are driven by our mission to make single-use a thing of the past and make reuse packaging the norm. Reusing packaging reduces the impact, and greatly minimizes the natural resource use of packaging. With our pioneering reuse packaging service and technology platform, we make reuse a reality for companies in the food and beverage industry. We are already breaking new ground with our meal-kit service, but the sky's the limit when it comes to reuse packaging. With partners we cover the full supply chain from packaging production and software development to sanitation and logistics making sustainability the easy choice for our customers.

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.

Using heated seats we can power 50 seats for the same energy as ONE heating lamp and 400 seats for a gas burner 400! 🤯 It gives you the potential to save money on electricity, provide better customer service, and help reduce emissions by +90% Imagine you are at a restaurant. When it gets late and the sun goes down, Instead of leaving the restaurant you can just turn on the heating elements in your cushion, and the evening can continue. Imagine how many great memories you can have in 10 years if every evening from now doesn't naturally stop when it gets cold?

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!;)
