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!;)

Rumett casts paper-free mineral wall panels from gypsum and bio-ash. The surface is finished at the point of casting — no paint, no filler, no finishing step. The panels are solid mineral with no paper facing, cast 13 mm thick in a 600 × 1200 mm reference format, and screw-fixed to a supporting steel or timber framework rather than glued. Because the fixings stay accessible, a panel can be removed and reinstalled in a new layout instead of being broken out. The panels are classified A1 for reaction to fire in accordance with EN 13501-1:2018, issued by DBI. The classification applies to the product defined in the report; coverage of sealed or lacquered variants remains to be confirmed. The report is available on request. Rumett is based in Copenhagen and won the Danish Design Award 2025 in Young Ideas. We work with architects and interior fit-out teams on sample requests and project documentation.

Treesy ApS er en dansk climate tech-startup, der gør det nemt, billigt og gennemskueligt for privatpersoner og virksomheder at tage konkret klimahandling gennem træplantning i Tanzania. Mange mennesker og virksomheder ønsker at gøre noget for klimaet, men oplever i dag, at løsningerne er uoverskuelige, dyre, abstrakte eller svære at stole på. Samtidig vokser både klima- og biodiversitetskrisen, og behovet for skalerbare, troværdige og handlingsorienterede løsninger er større end nogensinde. Treesy er skabt for at fjerne barriererne for klimahandling. Vi tilbyder en enkel abonnementsbaseret model, hvor kunder planter træer som en konkret måde at reducere og balancere deres klimaaftryk. Vores tilgang er baseret på konservative beregninger, radikal transparens og lokal forankring. Alle træer plantes i samarbejde med lokale partnere i Tanzania og bliver: • individuelt geo-tagget • monitoreret mindst fire gange årligt • passet og genplantet i op til tre år efter plantning Vi planter et diversificeret mix af træer med fokus på både klima, biodiversitet og lokal økonomi. Det betyder, at vores indsats ikke kun handler om CO₂, men også om at styrke økosystemer, skabe lokal indkomst og opbygge mere robuste lokalsamfund gennem agroforestry og frugttræer. Treesy adskiller sig ved at kombinere: • lav pris pr. træ • høj grad af transparens • direkte lokal tilstedeværelse • individuel geo-tagging af træer • en bevidst fravalg af dyre certificeringssystemer til fordel for direkte dokumentation Vores ambition er at gøre klimahandling tilgængelig for alle — og samtidig sikre, at indsatsen skaber reel, målbar og langsigtet impact. Treesy er stiftet af iværksættere med mange års erfaring fra udviklingsarbejde i Afrika og et stærkt lokalt netværk. Vi tror på, at ægte forandring skabes, når klima, biodiversitet og social udvikling tænkes sammen i én samlet løsning. Vores mission er enkel: At gøre det så nemt og gennemskueligt som muligt at give mere tilbage til planeten, end man tager.

Many people are talking about the smart grid and how we can reach 100% sustainable energy, and avoid global warming getting out of hand, by intelligently balancing the consumption so it fits with the electricity production. At True Energy we're already doing it! True Energy offers a smart charging app to our end users so they can register their car or charger and have it start or stop charging based on the hour of day and the electricity price, so the user optimizes their charging to be cheapest. The service is free of charge for the end user because they participate in our flexibility pool where the power companies can buy offsetting of the consumption if the grid is overloaded or production is expensive. We use Google Workspace, GitLab as code repo, Jira for our agile project management, and Slack for chat. We have a policy of 100% line coverage for unit tests, and want to support continuous delivery. We focus on collaboration and an open, inclusive work environment. Our team is multinational, and the working language is English, so full proficiency is required.. We have team members in several time zones.
