ReFlow is on a mission to support the decarbonization of the maritime industry. We are building a brand-new platform from scratch, designed to empower stakeholders with the tools and insights needed to drive sustainable change. We have a fun and social atmosphere, with an amazing location in the center of Copenhagen—right next door to the King and Queen! We’re a small, transparent team that shares insights into everything—from customers to numbers, the good and the bad. While we love working together in the office and prefer to have most of the team on-site, we're also quite flexible when it comes to remote work when needed. And did we mention the legendary post-lunch beer at the bar below? It's something you don’t want to miss! As a team, we win together, supporting each other every step of the way.

At Sustainary, we believe that human development is deeply interconnected with the environment and is essential in the fight against climate change. That is why we are dedicated to building a more open, inclusive and sustainable Denmark for future generations, with young people at the heart of our efforts. Through capacity-building projects focused on youth, we empower individuals to shape a future where people and nature thrive together. Since 2018, we have been designing and implementing high-impact initiatives that address both human development and environmental challenges, strengthening communities, organizations, and society in the pursuit of a greener and inclusive Denmark. With collaboration at the core of our approach, we work closely with private companies, public organizations and NGOs to amplify our impact. By fostering strong partnerships, we create innovative solutions, drive systemic change, and ensure a more sustainable and inclusive future for all. We are always open to discuss projects and partnerships in these above domains, with ambition to scale our activities and measured impact.

Our planet is overheating, biodiversity is reducing rapidly, and natural resources are being depleted. With 40% of global energy-related CO2 emissions and 30% of global landfill waste, construction plays a significant role in our planetary crisis and is by far the most polluting sector. We need to do things differently. Stykka takes you on a journey toward a future where the construction industry is part of the solution rather than the problem. We’ve set out to develop scalable solutions that enable like-minded developers and investors to build more sustainable, efficient and profitable. With Stykka we enable forward-thinking developers to build sustainably and be part of the solution rather than the problem. We use cutting edge technology like 3D scanning, digital fabrication, and distributed manufacturing to create new experiences and amazing, sustainable products for an array of clients.   With Stykka we aim to leave a positive impact on our planet and solve one of the biggest problems of our time, and we want you to be part of this journey.

Trebo is a cleantech startup that develops and manufactures a novel fluid-mechanical based plastic sorting technology. The sorting technology enables the plastic industry to sort large-scale plastic-type mixtures and transform the industry’s production waste into valuable resources. The Procurement costs on virgin materials are reduced and the environmental impact from incinerating or dumping plastic waste is eliminated. The annual global production of plastic has in 2019 exceeded more than 300,000,000,000 kg and even though the majority of plastic waste is suited for recycling purposes, more than 90% of the global production of plastic is either incinerated, deposited or dumped in nature. As the production of one kilogram of virgin plastic on average requires three kilograms of natural oil, the plastic industry is a global large-scale consumer of fossil fuels and therefore an important intrant in the green and sustainable changeover of the industry. Due to the wide palette of applications and physical characteristics of plastics, many end-user plastic products consist of one or more different types of plastic. As the quality and application performance of mixed plastic is decreased critically compared to the pure counterpart, plastic mixes are often considered as waste and therefore incinerated or sold to a price significantly lower than the price of the virgin plastic. Industrial waste streams of mixed plastic constitute approximately 60% of the total plastic waste stream. We believe it is critical to develop technologies that effectively sorts and restores the value and physical properties of the virgin plastic. At Trebo, we are environmentalists and our vision is to make the global plastic industry more sustainable and renewable. We hope that you will join us on our adventure.

A note from the Founder not generated by AI :D Have you ever thought about how amazing it is that we can instantly communicate with anyone around the world at anytime wirelessly? Personally, I have been intrigued by the devices and the invisible fields that connect us all since I was much younger. From the smartphone to the services that power it - and while they are great for everything they do, I felt the business model of selling phones and SIM cards hasn't really changed since the industry first began - more importantly to me it lacked heart and consideration for people and the planet. So about 2 years ago, I started working on Worthmore. Today, we're a small team on a mission to disrupt telecom for the good of people and the planet and redefine what a mobile phone subscription can be. We market Worthmore more as a membership to a community focused on making the world a better place first - not just a mobile phone subscription. Our goal is to transform your choice of telecom provider into a meaningful decision to become part of something bigger. In fact, we tell our members that they get the SIM card for free just for being a part of what we do. As a member, you enjoy the same great telecom services & prices (in most cases better or cheaper) - plus added perks of saving money at impactful brands and services. On top of this, for each member of our community, Worthmore pledges 15kr/mo to the "Worthmore Impact Fund," which supports people and tangible projects working towards a future we can all be proud of. See our first video here https://youtu.be/Vo9SuuD07jw?si=tYlO_Z0YUo0vOuFy The mission is to prove that in a dinosaur industry like telecom - doing good is good business. That by supporting causes instead of wasting money on ads, we can build a movement and a community that is connected by more than just the SIM cards in their devices. They are connected with a common goal of working towards a future we can all be proud of. We are still in the very early stages, and since I don't come from money, and I didn't start this with a small loan of a million dollars from my dad, it has been a struggle to even get this far...but we now have our first working SIM cards - we have our website - we have the basic skills, and most importantly, we have the motivation to keep pushing things forward. Every time I see that it says Worthmore in the top corner of my phone instead of Telia, Lebara, or whoever, I'm reminded that we have succeeded in building a way to help people #ConnectWithPurpose. So - As a founder with an extremely limited budget and nothing but an overwhelming sense of optimism and a passion for what he's building - I write this letter to reach out to those who also want to be part of our mission - we could use the help. I look forward to connecting with some of you soon for an interview, and if you've read this far, you're probably the type of person we're looking for :D Tegan Spinner CEO & Founder @Worthmore

Prezio is Europe's electricity price API, giving energy apps one integration for the true cost of electricity at any address, down to the quarter hour. Instead of stitching together market prices, grid fees, taxes and levies from thousands of retailers and grid operators, developers plug into one standardized schema and get accurate, real-time tariffs across Europe. Most electricity price data stops at the wholesale market rate, which is often only about a third of what actually ends up on the bill. Prezio adds the rest: retailer charges, grid transport and capacity fees, taxes and local levies, all kept current with daily updates. That means EV charging platforms, smart home and HVAC systems, solar and battery software, and energy management systems can schedule, bill and optimize on the real price a household or business actually pays, not a rough estimate. Founded in Copenhagen, Prezio's mission is to power the energy transition by making accurate, standardized electricity pricing data the default layer every energy app builds on, so product teams can focus on optimization instead of price plumbing.

UNYA Copenhagen is a volunteer-driven youth organization dedicated to empowering young people to engage with global challenges through the lens of the United Nations’ values and the Sustainable Development Goals. We create an inclusive platform where students and young professionals can learn, collaborate, and take action on issues like climate change, social inequality, peacebuilding, and innovation. We are addressing a clear and growing problem i.e. the disconnect between youth and global institutions. Many young people in Denmark care deeply about sustainability and justice but find it difficult to access meaningful opportunities to participate in international dialogue or contribute to real-world impact. This gap leaves motivated individuals without a channel to apply their energy, creativity, and ideas, while institutions miss out on fresh perspectives and engagement from the very generation that will inherit the future. UNYA Copenhagen bridges this divide by turning global ideals into local action. We organize interactive events, workshops, and panel discussions that make complex global topics accessible and relevant. Our activities are co-created by volunteers from diverse academic and cultural backgrounds who bring their own insights to the table. Through collaboration with universities, NGOs, and public institutions, we connect youth directly with experts and decision-makers, fostering a sense of shared responsibility and agency. What makes UNYA Copenhagen unique is our grassroots approach. We are not just an organization — we are a community that thrives on collective energy and creativity. Every project is designed by young people for young people, ensuring authenticity, inclusivity, and long-term motivation. Our strength lies in our diversity and the genuine commitment of our volunteers, who bring the UN’s global mission to life in a way that feels personal and actionable. The motivation behind UNYA Copenhagen is simple: we believe that youth engagement should not be limited to classrooms or conferences but should become a lived experience. We started this initiative because we wanted to make international dialogue tangible, local, and inspiring. Our team members share a passion for learning, community-building, and positive change — values that drive us to dedicate our time to building something meaningful together. Today, UNYA Copenhagen continues to grow as a platform where ideas turn into impact. We are seeking motivated individuals who want to gain experience in leadership, communication, and project management while contributing to a global cause. By joining The Hub’s Community Program, we hope to reach more passionate volunteers who want to be part of a dynamic network that connects Copenhagen’s youth with the world.

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.
