The 1KOMMA5° One-Stop-Shop for Building CO2 Neutral Homes

With a fragmented market that offers a multitude of different products to build a CO2 neutral home, it can be a daunting task for consumers to navigate. This is where 1KOMMA5° comes in - as a One-Stop-Shop that combines all the necessary technologies in one place, making it easy for customers to choose from various carbon-neutral energy solutions.

Micha Grüber, the CFO and CO-Founder of 1KOMMA5°, is responsible for managing the company's acquisition and funding. He emphasises the impressive business growth from scratch to a three-digit Euro range in 2022. When asked what excites him the most about 1KOMMA5°, he states, "We get to work on the most generational problem of our time. Even though decarbonising the world's buildings is no small task, it's one that we are dedicated to achieving."
