Reel is creating a new way of buying electricity to accelerate the renewable energy transition. We are on a mission to empower companies to make a positive difference for climate through the electricity they buy. Reel enables all companies to enter a new type of electricity contract (Power Purchase Agreement, PPA) that reduces CO₂ emissions by adding new renewable electricity to the grid. At Reel, our vision is a world running 100% on renewables. We aim to create significant climate impact by enabling companies to create new renewable energy, reducing their emissions and decarbonizing electricity grids.

At Ento, we help organisations monitor and optimise energy consumption across large building portfolios. By combining millions of data points with artificial intelligence, we translate complex energy data into actionable insights that make it easier to reduce energy use, meet regulatory requirements, and document real savings and impact. Ento works with organisations across Europe, including municipalities, retail chains, social housing providers, and asset and property managers. Today, more than one third of all municipalities in Denmark use our platform, alongside large retail and real estate portfolios in Italy and the UK, as well as some of Europe’s largest cities. Over 50,000 buildings run on Ento, helping customers save more than 15,000 tons of CO₂. Our team consists of 11 experienced people across 4 countries, with offices in Denmark (Aarhus and Copenhagen). We work in a hybrid setup, combining remote work with the flexibility to collaborate from the office when it makes sense. This way of working relies on trust rather than strict rules and gives people a high degree of autonomy. In return, we expect ownership, accountability, and intrinsic motivation.

We're making innovations for assessing marine biodiversity, essentially building underwater cameras and using AI to count fish. We're in the midst of a biodiversity crisis, the wildlife population has shrunk by 73% in the last 50 years alone, and it is especially bad in marine environments. At Anemo we monitor the effect of man-made structures on the marine environment to help our clients comply, quantify impacts, and continually improve nature-positive outcomes.

We've built Charger Health, an AI-powered Operations & Maintenance platform for EV charging networks. Our software automatically identifies issues and initiates resolution flows in real-time. This is done through combination of pattern recognition, machine learning models and an agentic infrastructure. In addition, our solution automatically creates, updates and closes tickets, optimizing the throughput of operations teams. Lastly, intelligent alerts reveal hidden issues and enables proactive remote handling. This has reduced the operational resources required to manage the network, enabling operations teams to more than double their output, while also improving key performance metrics such as uptime and charging success rate.
