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!;)

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.

At Rejoose, we believe traditional business transactions lack transparency when it comes to their environmental impact. In essence, they leave a hidden cost – carbon emissions – unaccounted for. This creates several challenges for companies: Blind spots in sustainability: Without knowing the carbon footprint of each transaction, setting and tracking progress towards emissions reduction goals becomes a guessing game. Informed decision-making hurdles: Sustainable choices often involve trade-offs. Without clear data, prioritizing actions to optimize environmental impact becomes difficult. Stakeholder engagement struggles: Customers and investors demand environmental accountability. Traditional invoicing offers no way to showcase your commitment with concrete data. Compliance concerns: Regulations around carbon reporting are tightening. Ignoring transparency can lead to penalties and missed opportunities. This is where Rejoose e/voice steps in. We seamlessly integrate carbon emission data directly into your invoicing process. Think of it as transforming financial transactions into powerful sustainability statements. Every transaction now carries valuable insights into your environmental footprint, empowering you to: Pinpoint and tackle emission hotspots: Identify areas in your supply chain and operations where emissions are highest, allowing you to prioritize improvement efforts. Tell your sustainability story: Communicate your commitment to a greener future with transparent, data-driven reports that resonate with stakeholders. Make a real difference: Take informed actions that minimize your environmental impact, contributing to a more sustainable future for all. At Rejoose, we believe transparency is key to sustainable business practices. Let e/voice be your guide to unlocking valuable insights and taking concrete steps towards a greener future.

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. With the average car sitting idle 22 hours a day,  there had to be a better way to put the cars parked on our streets to better use.   By providing a safe and seamless way for people to share cars with each other we want to change the way the world thinks about car ownership.
