Philipp Schröder

Overview
Philipp Schröder is a German cleantech entrepreneur and the co-founder and Chief Executive Officer of 1KOMMA5° (styled 1Komma5Grad), a Hamburg-headquartered residential-energy platform he co-founded in 2021. Before founding the company he held senior operating roles in the European energy-transition industry, including Country Director of Tesla Germany and Austria and Managing Director of the battery-storage company Sonnen.
Why this entity matters
Schröder is one of the most visible operators in the European home-energy transition. Under his leadership 1KOMMA5° reached unicorn status within roughly two years of launch, making it one of the fastest-scaling German cleantech companies of its cohort. He is closely associated with the argument that private households — bundling rooftop solar, home batteries, heat pumps and EV chargers under intelligent software — can become the backbone of a decentralised, software-orchestrated electricity system, and he is a frequent public commentator on German energy and innovation policy.
Career, company, or institutional background
Schröder studied law at the University of Hamburg before moving into the cleantech industry. As Managing Director of Sonnen and then as Country Director for Tesla in Germany and Austria, he worked inside two of the most prominent companies of the early European energy-storage and electric-vehicle markets. In 2021 he co-founded 1KOMMA5° and has served as its CEO from inception, building the company into an installer-and-software group offering solar panels, batteries, heat pumps and charging hardware to private households, together with the proprietary Heartbeat AI energy-management platform.
Role in the startup, technology, investment, or innovation ecosystem
1KOMMA5° positions itself as a New Energy company aiming to decarbonise European households. The business combines physical installation with an AI control layer, Heartbeat AI, that shifts household consumption to the cheapest and cleanest hours and aggregates connected homes into a virtual power plant; the company reported reaching one gigawatt of shiftable load across its fleet in 2026. The company has raised substantial equity, closed one of the largest European cleantech rounds of its period, and has expanded across several European markets and Australia, employing on the order of 2,500 people. A later-stage financing round was reported in 2025 ahead of a potential public listing.
Selected relationships and affiliations
Schröder co-founded 1KOMMA5° alongside a founding team that public reporting identifies as including Jannik Schall, Micha Grüber, Michael Hinderer and Philip Liesenfeld. His earlier professional affiliations include Tesla and Sonnen. He is a recurring voice at European technology and cleantech conferences and in German business media on energy-transition and regulatory topics.
