The company achieved this growth while maintaining profitability, with the company previously reporting operational profit (EBIT) of approximately €50 million. The company plans to invest over €100 million from 2025 to 2027 in expanding its Heartbeat AI software business, which manages Europe's largest virtual power plant for residential customers with over 500 megawatts of flexibility capacity and approximately 40,000 connected energy systems. 1KOMMA5° has raised approximately €400 million in total equity since its founding and remains debt-free, with an unused credit line of €100 million.
