German energytech unicorn 1KOMMA5° has reached a valuation of $1.35 billion in its latest financing round as it prepares to increase investment in its AI-powered energy management business.
The Hamburg-based company plans to invest more than €100 million in its energy AI platform, Heartbeat, in 2027.
Heartbeat AI is designed to automate energy management processes, including electricity trading, billing, and metering, as part of the company's broader focus on home electrification.
1KOMMA5° is also considering expanding into the United States next year, with CEO Philipp Schröder pointing to strong investor interest as a factor behind the potential move
. Speaking to Reuters, Schröder said:
"We're considering entering the US, because we've seen how much drive and how much interest from investors is actually behind that."
The company is also keeping the possibility of a US initial public offering under consideration.
According to Schröder, its financial performance in 2027 will be a key factor in determining whether and when to pursue a listing.
1KOMMA5° previously shelved its US IPO plans in April 2025 amid market uncertainty linked to President Donald Trump's renewable energy and trade policies.
In October last year, 1KOMMA5° filed a complaint with the European Commission over the German government's plans to subsidise at least 20 GW of new gas-fired power plants by 2030.
The company argued that the proposed subsidies would distort competition, increase electricity costs, and disadvantage decentralised renewable energy solutions such as virtual power plants. At the time, it said it was already aggregating more than 600 MW of flexible energy capacity through its network, with ambitions to reach 20 GW by 2030.
The latest financing round and planned investment in Heartbeat AI reflect 1KOMMA5°'s efforts to expand its energy management technology while evaluating opportunities for international growth and a future public listing. The company reaffirmed last month that it is targeting approximately $750 million in revenue for the 2026 financial year.
