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creates a time-consuming and frustrating experience for shoppers to locate desired items among incomplete listings and outdated platforms.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.

Auxilium Infrastructure Partners develops, owns, and operates flexible energy assets that help stabilize the electricity grid while creating new revenue streams for industrial sites and asset owners. The electricity system is becoming increasingly volatile as more wind and solar power enter the grid. This creates a growing need for fast, reliable flexibility: assets that can consume, store, or release power when the grid needs support. Today, many industrial sites have unused grid capacity, heat demand, backup systems, or space for batteries, but lack the technical platform, market access, and operational expertise needed to turn that flexibility into revenue. Auxilium solves this by combining physical energy infrastructure with proprietary software. We deploy and operate assets such as battery energy storage systems, electric boilers, load banks, and other controllable loads. Our platform connects these assets to energy markets and ancillary service markets, allowing them to support grid stability, optimize power consumption, and generate income. We handle the full process from site assessment and technical design to installation, operation, market participation, monitoring, and optimization. This gives customers a simple way to monetize their grid connection or energy assets without needing to build their own trading, control, or compliance capabilities. Our mission is to accelerate the green transition by making distributed energy flexibility scalable, investable, and easy to deploy.

We are building large-scale robots with computer vision to sort all waste in extremely high purity.

Bio-compostable plastic is already used in many industries today. GRØNBLÅ goes much further. As a solutions partner, GRØNBLÅ helps companies and brands to push their green and sustainable efforts to a new level. GRØNBLÅ wants to create a true circular economy: First and foremost is the use of proven and certified bioplastics for packaging and accessories. A take-back program to ensure that the bio-compostable material is collected without being mixed with other material and composted in special facilities. In addition, GRØNBLÅ is working intensively with renowned research partners to further optimize the process of composting using bacteria and enzymes. Our goal is to offer high-performance bio-compostable materials and create true closed-loop solutions where the material is not discarded after use but returned to nature in an environmentally friendly way.

ARIS Robotics was founded by a shared vision: to steer the world towards a greener future. One of the critical challenges in the green transition is how we manage our resources and waste. Today’s processes are highly linear: raw materials are extracted, processed into products, used a few times, and then discarded—either incinerated or buried in landfills. We aim to change that. At ARIS, our ultimate goal is to create a world without waste. This means transforming linear processes into circular ones. The first step towards effective recycling is good sorting. We develop scalable and automated solutions using deep learning to recognize and sort waste efficiently. Currently, we are serving our beachhead market—public recycling centers. Here, we assist visitors in correctly sorting their waste, extending the lifespan of materials and reducing the need to extract more raw materials from our limited planet. We are always on the lookout for passionate individuals to join our mission. Keep an eye on our open positions, follow us on LinkedIn, or feel free to send us a motivated application. Let’s create a greener future together!

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.
