Hamburg-based home electrification company 1Komma5° plans to enter the US next year, after a new financing round valued it at $1.35bn (around €1.2bn), according to Reuters.
The company did not disclose the size of the round or who invested. It said it will put more than €100m into Heartbeat, its energy AI platform, in 2027.
“We’re considering entering the US, because we’ve seen how much drive and how much interest from investors is actually behind that,” co-founder and CEO Philipp Schröder told Reuters.
Heartbeat is the software that links the solar panels, batteries and heat pumps 1Komma5° installs in customers’ homes. The company runs it as a virtual power plant and wants to use it to automate energy trading, billing and metering.
The US plans also bring back the question of a listing. 1Komma5° shelved plans for a US IPO in 2025, after President Donald Trump’s renewable energy and trade policies unsettled markets.
Schröder told Reuters that the company’s performance in 2027 will be key to deciding when, and whether, to go public in the US.
That marks a shift from his view last November. When Impact Loop sat down with Schröder at Slush in Helsinki, he said a European listing had come into the frame.
“Nasdaq was our obvious choice when we first looked at it,” he told Impact Loop at the time. “Right now I think we would probably seriously consider a European listing as well.”
He also said it was too early to commit either way, with so much uncertainty around Trump, China and Europe.
“There might just be a couple of slight changes and then the entire assessment is you have to reassess it,” he said.
Founded in 2021, 1Komma5° has raised close to €400m in equity, according to the company. Its backers include Hamilton Lane, CalSTRS, Porsche Ventures, Eurazeo and Norrsken.
In September, the company confirmed it is aiming for revenue of around $750m in the 2026 financial year.
