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!;)

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.

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.

At North ESG, we’re building the AI-powered ESG accounting software for SMEs. 99% of all companies in Europe are small and medium-sized enterprises. They drive our economy - but when it comes to sustainability, they are underserved. ESG reporting is complex, time-consuming, and an administrative hassle. We believe the future of ESG should be about growth - not admin. Our mission is to free up time and strengthen the ESG profile of SMEs as a commercial advantage, so they can stay competitive, win more business, and meet rising demands from customers, regulators, and investors. Our platform automates the entire ESG reporting process using AI - from data collection to emissions calculations and EU-aligned reporting. It integrates with ERP systems and leverages both public and private data sources to generate tailored, commercially viable ESG reports. We’ve already gained strong market traction across industries in Denmark. And with ESG requirements increasingly cascading down from large corporates and financial institutions, we’re solving a growing pain for millions of SMEs across Europe.

Klima Biler er sat i verden for dem, der går med tanker om at anskaffe sig en klimavenlig bil. Hos KlimaBiler.dk er der ingen benzin- og dieselbiler, medmindre der er tale om hybridbiler. Vi har fokus på klimavenlige biler og dermed fremtiden. Vi hører selv til i kategorien af dem, der elsker lyden af en V8’er! … men det er lyden af fortiden, det er lyden af afbrænding af fossile brændstoffer. Vi er også fuldt ud bevidste om, at det kan diskuteres, hvilke biltyper der forurener mest fra vugge til grav, og problematikker omkring rækkevidde, manglende ladestandere og ladetid. MEN jo flere der kører klimavenligt, jo hurtigere går udviklingen af de grønne teknologier, og jo hurtigere går det med at nedbringe de børnesygdommene med førnævnte problematikker. Derfor ønsker vi at kickstarte den udvikling og få så mange klimavenlige biler på vejene som muligt. Vi pudser ikke vores glorie! Vi glemmer også at slukke lyset og har masser af vaner, der er meget lidt klimavenlige, men stille og roligt bliver vi mere og mere bevidste om de valg der kan gøres anderledes for at belaste klimaet mindre. Det samme gælder KlimaBiler.dk. Der er masser af ting, der kan gøres bedre for den besøgende eller for dem, der sætter deres bil til salg på klimabiler.dk … der kan vi heldigvis undskylde os med, at vi er helt grønne. Men nu er vi i gang og som med el- og hybridbiler, er det et skridt i den rigtige retning. Og vi er altid åbne for forslag til forbedringer eller ideer til indhold på siden. Jo flere biler, der bliver sat til salg på klimabiler.dk, jo hurtigere og jo bedre kan vi udvikle websitet og markedsføringen og dermed få flere klimavenlige biler på vejene. Ambassadør for klimaet! Vi synes, at man ved at køre i en klimavenlig bil viser sin holdning til klimaspørgsmålet og er med til at få tvivlerne over på den grønne bølge. Man bliver ambassadør for klimaet og er med til at vise vejen til et bedre klima i alle henseender, for vi ser klimavenlige biler som fyrtårne for udviklingen af grønne teknologier generelt. Og bla. Tesla har vist, at klimavenlig teknologi og biler bestemt ikke behøver at være kedeligt.

There are one billion cars in the world, a number that is set to double in the next 10 years—we’re doing everything we can to stop that from happening.   Getaround was founded to change the way that people think about cars.
