Despite a challenging market for solar systems and heat pumps, Hamburg-based CleanTech startup 1KOMMA5° achieved a record €520 million in revenue for 2024—growing its organic sales by 36% to €490 million—while remaining debt-free and expanding its Heartbeat AI energy management platform, according to its preliminary business figures for 2024.
The company increased its total revenue close to €520 million in 2024, up from around €450 million in 2023 – despite “a recession and declining demand” for solar systems and heat pumps.
Adjusted for acquisitions, 1KOMMA5° achieved the strongest growth in its history, with organic sales rising from €360 million to €490 million in 2024; this underscores the company’s claim to European market leadership in the megamarket of home electrification.
Philipp Schröder, CEO and Co-founder of 1KOMMA5°, states: “Even in the midst of a crisis year and in a shrinking market environment, we are growing by 36 percent. This is a great success for the entire team. We have made significant investments in Heartbeat AI and the smart meter rollout in 2024.
“Despite sourcing polysilicon from Germany, which is far more expensive than production in Asia, and facing rising sales costs, we remain sustainably profitable on an operational level and debt-free. Over the last two years, we have consistently increased our revenue and profits without using an already approved credit line in 2024.”
Founded in 2021 by Jannik Schall, Micha Grueber, Michael Hinderer, Philip Liesenfeld, and Philipp Schröder, 1KOMMA5° now employs around 2,500 people worldwide. They are a CleanTech startup for CO2-neutral energy, heat and mobility. The company operates around 80 locations in 7 markets worldwide, serving as the one-stop shop for intelligent, integrated energy solutions such as photovoltaics, electricity storage, heat pumps and EV charging stations.
Its core technology is the energy management software Heartbeat AI; it currently optimises more than 40k systems, creating “Europe’s largest virtual power plant” that connects customers with the energy market and controls electricity generation and sales in time with the wind and sun.
Heartbeat AI enables customers to benefit from the volatility of renewables: Surplus feed-in, self-consumption benefits and AI-optimised grid consumption can generate more revenue than costs. Instead of charging margins on electricity as an energy supplier, 1KOMMA5° charges a flat-rate software fee and thus enables dynamic and individual electricity prices in real-time instead of conventional fixed tariffs.
1KOMMA5° has reportedly already installed over 300k decentralised, controllable energy systems, creating CO2 savings of 14 million tonnes. By 2030, the company aims to convert more than 1.5 million buildings to a climate-friendly energy supply, thus contributing to achieving the Paris climate targets.
In the next three years, the company plans to invest €100 million in expanding its software business centred around Heartbeat AI; by 2025, it is expected to grow to sales in the double-digit million range.
In November, 1KOMMA5° announced the spin-off of Heartbeat GmbH as its own subsidiary under the leadership of CTO Barbara Wittenberg and CPO Jannik Schall. The aim is to achieve an annual revenue of €10 billion from hardware and software sales in 2030.
1KOMMA5° has raised around €400 million in equity since its foundation and is debt-free, and a credit line of up to €100 million provided in 2023 has not yet been utilised.
