About 1KOMMA5°
1KOMMA5° is Germany's fastest-growing climate tech scaleup, founded in Hamburg in 2021 by Philipp Schröder. The company combines hardware installation (solar panels, home batteries, heat pumps, EV wallboxes) with a proprietary software platform — Heartbeat AI — that optimises energy consumption and participation in energy markets. Its €150M round in 2024 and valuation above $1 billion confirm 1KOMMA5°'s position as one of Europe's first unicorns in home electrification.
The Story
Founded in 2021 by Philipp Schröder, former CEO of SolarCity Europe, on the thesis that the domestic energy transition required a vertically integrated hardware + software operator.
