THE PROBLEM Searching second-hand online requires navigating hundreds of platforms and incomplete listings, forcing shoppers to do the heavy lifting of finding and comparing relevant items. The decentralized and the fragmented second-hand market creates a time-consuming and frustrating experience for shoppers to locate desired items among incomplete listings and outdated platforms. THE SOLUTION Koral aggregates millions of second-hand listings into one searchable platform with categorized, indexed data to create a one-stop solution. This eliminates tedious searches across individual platforms, making shopping second-hand is easier by improving discoverability and streamlining the process of finding desired items online.

We are an impact-driven startup from Denmark with the mission to make zero-waste constructions happen with our circular material platform. Our product is an end-to-end solution that leverages data and automation to make it easy to efficiently plan, manage, and circulate building materials. We are a team of experts in engineering, construction and enterprise SaaS development, and we are turning material waste into profits for construction projects. More importantly, we avoid up to 1.5% of the global CO2eq emissions resulting from the construction industry.

We are HEMBOO: an early stage start-up with the vision of making low emissions, renewable materials the norm in construction. Besides fossil fuels, the production of concrete is the worst emitter of CO2 in the world. However it is the most used material within the construction sector. But not for long: climate legislation is about to make concrete a whole lot more expensive, by introducing a CO2 TAX. This leaves the construction companies with a problem as there is no valid sustainable alternative they can use. HEMBOO offers an easy solution: prefabricated walls for new construction made of hemp and bamboo with a reduction of 80% CO2 emitted compared to the traditionally used concrete walls. BUT the construction industry is very conservative and risk-averse. Therefore getting to market is a long journey. We built our first prototype are now preparing for the second one and are gathering data on the needs of our customers. Our aim is to provide a solution similar enough in prefabrication and installation methods, to make the transition from concrete fast and easy. Our element is designed for large scaled production so that we can have the largest impact. Recently we have received a total of 520.000 dkk in soft funding for product development and are participating in multiple startup support programs so it is full speed ahead! The team behind it all: We are a diverse team of three, Elsa Maria Iuliano, Helena Brandt Rejndrup and Michael Hallam. Helena and Elsa graduated as architectural engineers from DTU while Michael is finishing up his studies in design and entrepreneurship. We started HEMBOO because we are all very passionate about making an environmental impact. As a team we have a lot fun together, while still being productive. We emphasize a friendly environment where we help each other even though everyone has individual responsibilities. Currently looking to expand and we want you to be a part of it! Reach out if you are interested in getting on board. We are particularly interested in commercial, communication and financial competencies. Based in our joint office spaces in the center of Copenhagen and at CBS in Frederiksberg. And yes they do they do have Friday bars :-) Feel free to contact us with any questions!

Our team brings together experts from widely varying disciplines: from atmospheric chemistry to pollution monitoring, from fluid dynamics to environmental health and from economics to engineering and design.

Tepui Agentic Labs is Europe’s first AI-native agentic data platform , built in Denmark from the ground up on EU-sovereign infrastructure for mid-market businesses trapped on legacy systems. Most mid-market companies across Europe are sitting on years of valuable business data locked inside outdated databases, spreadsheets, and disconnected systems. They have no data team to fix it, and enterprise solutions are priced for companies ten times their size. The result: critical business decisions made on gut feel, manual reports that take days to assemble, and institutional knowledge trapped in files nobody dares to touch. Tepui solves this with three product lines. Datarcon modernises legacy data, extracting, cleaning, and transforming it into a modern analytics layer the business actually owns. Our Sovereign SaaS platform lets companies run AI-powered tools on EU infrastructure with no data leaving European soil ,fully compliant, fully controlled. And Tonin, our autonomous 24/7 AI agent, monitors the business continuously, triggers alerts, generates reports, and answers operational questions in plain language. Tonin is not a chatbot , it is an always-on intelligence layer that works while the team sleeps. A standout feature of our AI agents is the Consciousness Core , an integrated ethics layer ensuring responsible AI behaviour and compliance with the EU AI Act from inception. Every agent decision is traceable, auditable, and explainable by design. The platform is built on an enterprise-grade 7-layer security architecture, fully EU-sovereign with no data leaving European soil. We serve multiple industry verticals across Denmark hospitality (restaurant groups, hotels), construction (mid-market contractors), social housing (almene boligorganisationer), investment funds (PE, VC, family offices), food suppliers, automotive (parts distributors, dealer groups), and law firms with additional verticals in development. Every vertical has the same problem: years of data locked in systems that never talk to each other. Same core product, different industry configuration. We are pre-seed, incubated at ITU NextGen Incubator 2026, and actively pursuing first pilot clients in Denmark.-sovereign deployment on European infrastructure as standard. Made in Denmark. Built for Europe.

Kvasir is solving one of the most difficult problems in the world; how to replace fossil fuels in the heavy transportation industries. Kvasir has developed and patented a unique process to convert ligno-cellulosic plant biomass (straw, wood, bagasse etc. ) to marine fuel in a simple one step process. The process involves cooking biomass in an alcohol atmosphere under pressure, effectively liquefying the biomass. Were developing our technology in our in-house lab and workshop facilities in Soeborg and are also collaborating with universities in both Denmark and abroad.

Millions of products worldwide run on electricity, requiring different chargers, batteries, and plugs to work. Here at BYGGO Design, we are working to re-invision and universalise power supply. Our innovative solution with unrivalled efficiency can charge all electrical products, reducing greenhouse gas emissions and E-waste.

We are devoted to accelerating the development and adoption of technologies that can help fight climate change by actively removing CO2 from the atmosphere. The challenge We are emitting 50 Gigatons of CO2 every year, and that needs to be reduced by at least 80%. However, that still leaves 10 Gigatons of CO2, and we need to get all the way to zero. Trees are great, but we need many more solutions as well if we are to get to zero. Currently, most of these are way too expensive (and limited in capacity) for companies to use. We've developed a platform that combines methods and makes it available to every company that wants to compensate their emissions. We work with cutting edge technologies, including Direct Air Capture, Bio char, Bio oil etc.
