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!;)

At Radimet we make radon measurements easy. Radon is a radioactive type of gas, responsible for more than 20,000 cases of lung cancer in the EU every year. Radon is in the underground everywhere and only by measuring the levels is it possible to improve the levels by making installations such as improved ventilation and the like.

ParkNotice er en dansk startup, der digitaliserer parkeringsafgifter. Hvert år udstedes over en halv million parkeringsbøder i Danmark, men processen er stadig analog og papirbaseret. Vi vil gøre det smartere, hurtigere og mere brugervenligt for både bilister og parkeringsselskaber. Med ParkNotice kan bilister modtage deres parkeringsafgifter digitalt — via app, e-Boks, SMS eller push-besked — så de undgår papir på bilruden, forsinkede breve eller bøder, der forsvinder. Samtidig sparer parkeringsselskaber og kommuner tid, penge og papir. Løsningen kan på sigt udvides til andre typer af bøder, men vi starter med parkeringsbøder, hvor problemet er størst og mest presserende.

Livestock production is one of the largest contributors to global methane emissions. As the demand for meat and dairy grows, so do emissions. Our planet cannot afford this trajectory, but together, we can change it. We know that fighting climate change requires bold action backed by science. What if we could slash livestock methane emissions by 80 percent? We’re developing an innovative, nature-based solution designed to scale globally and deliver significant, lasting impact.

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.

Velkommen til Plando - ejendomsbranchens digitale platform til vedligeholdelse og forbedring af bygninger med fokus på energiforbrug, udledning (CO2e) og totaløkonomi. Vores værktøj hjælper bygningsejere, ejendomsadministratorer og rådgivere med at træffe langsigtede og bedre beslutninger for deres ejendomme. Plando gør det nemt og overskueligt at arbejde med vedligeholdelse og forbedring af en ejendom - eller hele ejendomsporteføljer. Samtidig sikrer Plando overblik over bygningers CO2e-rejse og energimærke - noget som kun bliver vigtigere i fremtiden, hvor krav om bæredygtighed og ESG-rapportering (virksomheders miljømæssige, sociale og ledelsesmæssige rapportering) vil fylde endnu mere. Vi drømmer om en ejendomsbranche, der vækster i værdi gennem bæredygtige forbedringer. For vi lever i en verden, hvor vi ikke har råd til at spilde flere ressourcer. Derfor har vi besluttet os for at gøre op med vores branches ’sådan har vi altid gjort’ -måde at gøre tingene på og finde en ny vej. Vi mener, at det er på tide, at vi tager springet ind i en smartere måde at arbejde med ejendomsudvikling på. Vi holder til i det tidligere mejeri Enigheden på Rentemestervej i København NV. Vi leder løbende efter nye talenter, så tøv ikke med at kontakte os, hvis du vil være en del af vores team i Plando.

Os Om Havet er en frivillig organisation, der ønsker at sætte fokus på forurening af verdenshavene. Det er et stigende problem for de marine økosystemer. Omkring 70 procent af al affald, der ender i havet, synker til bunds. Her kan det have store konsekvenser for havmiljøet og er samtidig utilgængeligt for traditionelle oprydningsmetoder. Os Om Havet holder derfor arrangementer, hvor dykkere og andre ildsjæle fra hele Danmark samles og i fællesskab rydder op både over, under og i havet. Vi tror, at en god oplevelse i naturen kan skabe motivation og engagement til at handle på nogle af de store udfordringer, miljøet står overfor. Os Om Havet er mere end svømmefødder og iltflasker. Med foredrag og skoleforløb ønsker vi at udbrede budskabet og gå sammen om at få skabt en bæredygtig fremtid, hvor mennesket og naturen i højere grad forenes. Kom og bliv en del af fællesskabet! Hvis man gerne vil sikre sig, at Os Om Havet fortsætter kampen mod forurening af vores havmiljø, kan man blive Os Om Havet støttemedlem for 200kr årligt. Der er massere af fordele ved at blive et Os Om Havet støttemedlem: udover at hjælpe os med fortsat at kunne afholde events mm. har vi sørget for en række rabataftaler med vores samarbejdspartnere, mulighed for at låne vores affaldsindsamlingsgear året rundt, og ikke mindst vil man modtage Os Om Havets nyhedsbrev, så man aldrig behøver gå glip af et fremtidigt arrangement. Hvis du har lyst til at støtte vores arbejde, skal du sende os en e-mail på medlem@osomhavet.dk med navn, e-mail og telefonnummer - så kontakter vi dig.

We create building materials for modern sustainable and toxic-free buildings combining hundreds of years of knowledge and tradition with modern production- and building techniques. Our aim is to make sustainable building commercially viable. Our first product is Lundby Pladen - a strong and fireproof building board made of unburned clay and woodfiber, designet for classic dry-wall construction. In the sustainable building industry there has been a long anticipation for this product. Unburned clay is the optimal material for inner walls in vapor diffusionon open building techniques as preferred in biobased sustainable building. With a strong and light building board we have solved the problem of unburned clay solutions being either too slow, heavy, fragile or expensive for commercial building. The building industry is responsible for between 17-40% of the worlds Co2 emissions. With Lundby Pladen it will be possible to fireprove biobased buildings with a low-emmission, toxic-free and environmentally harmless high quality material, and thus help making our buildings a genuine Co2-storrage instead of as now, a major Co2 polluter. In the coming years the building industry is facing new environmental laws, and will be increasingly depending on products like Lundby Pladen. We experience a major pull from the marked. Building supply markets, architects, craftsmen, standart house developers and entrepreneurs are waiting impatiently for our product to hit the marked.

We believe in heating people rather than areas. 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?
