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!;)

Real-Time LCA is a powerful platform that enables companies to understand, reduce, and document the climate impact of their building projects during design and construction. 🏘️ By automating LCA calculations, it reduces the effort required for impact assessments by 50-90%. Users can perform collaborative, efficient, and accurate Life Cycle Assessments (LCA) that comply with international standards, certification schemes, and regulations. The platform streamlines LCA processes from BIM to reporting, allowing all stakeholders to visualize, track, and document carbon emissions to meet regulations, reported through our standard templates, or leverage your sustainability data in other applications through our API. 🙌

Agoprene is a biotech startup based in Oslo and Copenhagen. Agoprene is developing furniture foam from biomass to help the furniture industry reduce their need for petrochemicals. ​ Globally, furniture foam, which is derived from petroleum, accounts for 105 million tonnes of CO2 emissions annually. One armchair for example, emits an average of 43 kg CO2e, almost half of which is due to furniture foam. ​ Agoprene's foam is completely free of petrochemicals. We believe finding planet-friendly alternatives isn’t a challenge; it’s an opportunity.

Klimakampen er en start-up, der laver klimakampagner for arbejdspladser, folkeskoler og gymnasier. I hold dyster ansatte og elever om at få klimavenlige vaner. Lidt en "Vi Cykler Til Arbejde", bare med klima. Konkurrencen varer typisk 4 uger og faciliteres i vores egen app. Her vælger man hvilke pointgivende aktiviteter man har udført og ser statistik for hvordan man klarer sig og hvor meget CO2 man har sparet. Vi afholdt flere kampagne med betalende kunder og forsøger nu at skalere. Vi sidder på kontor på KU Lighthouse - Tagensvej 16a Vi er tre i teamet. Nicolai der er klimaspecialist. Dan, der er programmør og Kristian, der er klimaformidler. Vi søger en til at hjælpe med kommunikation, salg og marketing.

Plastic Change en dansk miljøorganisation med et ambitiøst internationalt sigte Vi arbejder hårdt med at knække den stigende kurve over plastikspild. Plastik er overalt – på land og til vands. Tre generationers forbrug af plastik har sat sine spor. Kun en lille del bliver genbrugt eller destrueret. Resten ligger i naturen i hundredvis af år. Vi arbejder for at reducere vores enorme plastikproduktion ved blandt andet at eliminere unødvendig engangsplastik fra vores produkter, ved at sætte bedre rammer for hvordan vi designer produkter til mere genbrug, og det plastik vi ikke kan genbruge, skal vi kunne genanvende. Vi arbejder både på politisk niveau, sammen med befolkningen, i samarbejde med innovationspartnere, på internationalt niveau, sammen med forskere og med at uddanne vores fremtidige generationer om problemet. Plastic Change består af et fast dedikeret team og en række uundværlige frivillige kræfter. Alle yder en stor, uvurderlig og professionel indsats for, at organisationen kan gennemføre sine ambitioner om at knække kurven for plastikproduktion og hermed plastikforurening.

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.

Incremental Maritime is developing a digital compliance solution that helps shipowners and operators navigate complex decarbonization regulations; transforming compliance into lower emissions and higher margins. Our deep regulatory expertise, data-driven models, and hands-on client support are what set us apart. Global shipping faces an accelerating tide of climate regulation, from the IMO’s GHG Fuel Intensity targets to FuelEU Maritime and EU ETS. These rules impact everything: fuel costs, asset values, and day-to-day operations. Yet most market players lack the tools and insights to respond; let alone turn compliance into an advantage. This leaves shipowners and operators asking: - What decarbonization investments make financial sense? - How do I reduce risk and avoid penalties? - Can I stay compliant across multiple regimes without extra complexity? - Without smart tools, these questions are hard to answer - and costly to get wrong. Our solution has two core parts: Advisory with immediate impact: We help clients assess regulatory costs, model emissions, evaluate investment cases, and support decision-making from planning to operations. A digital compliance agent (in development): Built on real client work, this tool will combine - Real-time emissions tracking - Cross-jurisdictional compliance logic - Commercial impact analysis - Support from pre-fixture to post-voyage We’re building the go-to compliance engine for modern shipping: one that simplifies decisions, protects margins, and scales with regulation. We launched Incremental Maritime because we saw a blind spot: climate regulation was outpacing the industry’s ability to respond and the result was confusion, cost, and missed opportunity. With experience spanning maritime operations and regulatory systems, we knew we could help. We believe that smarter compliance is not a burden, it’s a pathway to performance. We're here to equip shipping with the tools to decarbonize profitably, one fixture, one voyage, one regulation at a time.

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.
