1Komma5Grad

1Komma5Grad is a German climate-tech company founded in 2021 and headquartered in Hamburg. The company provides integrated residential energy solutions, including solar photovoltaic systems, battery storage, heat pumps, and electric vehicle charging infrastructure. It combines hardware installation with a digital energy management platform that optimizes energy consumption and enables participation in virtual power plant and flexibility markets. The brand targets homeowners and small businesses seeking to decarbonize their energy use and reduce costs. Operating primarily in Germany and expanding across Europe, 1Komma5Grad positions itself as a one-stop shop for the energy transition, offering consulting, installation, and ongoing energy services. The company has grown through acquisitions of local installers and partnerships, aiming to build a pan-European platform for decentralized energy. Its business model emphasizes bundled solutions and recurring revenue from energy services, differentiating it from traditional installers.

1Komma5Grad was founded in 2021 by Philip Liesenfeld, Jannik Schall, Micha Grüber, and Tobias Schütt with the vision of accelerating the adoption of residential renewable energy solutions. The company started in Germany and quickly expanded through acquisitions of local solar and heating installers, building a network of subsidiaries across Europe. By offering bundled products and a digital platform, it aimed to simplify the customer journey for home energy upgrades. In 2022, the company raised significant venture capital to fuel its growth and acquisition strategy. It has since launched its energy management software and virtual power plant capabilities, allowing customers to monetize flexibility. As of 2024, 1Komma5Grad operates in multiple European countries and continues to scale its platform.
