1KOMMA5° Hits $1.35 Billion Unicorn Mark With €70 Million Round

1KOMMA5° has closed a €70 million funding round at a $1.35 billion valuation, according to ESG Today. The home energy cleantech startup now holds unicorn status.

The raise puts 1KOMMA5° past the $1 billion private-market threshold. At $1.35 billion, the company ranks among Europe's most heavily valued privately held residential-decarbonization players.

What the source confirms

ESG Today's reporting locks in four data points. The company raised €70 million. Its valuation sits at $1.35 billion. It carries a unicorn designation. It operates in the home-energy cleantech vertical.

That is the whole of the confirmed record. The headline does not specify what currency the valuation was set in, what share class was issued, or whether the round involved primary or secondary shares.

What a "unicorn" means here

The unicorn tag applies to any privately held company that clears $1 billion in valuation. The term entered venture-industry usage in 2013 and skews toward U.S. software firms. Cleantech names have entered the tier more selectively.

For 1KOMMA5°, the label functions as a market signal. The company now sits inside a small European cohort of $1-billion-plus residential-decarbonization firms.

What the source leaves out

ESG Today's headline does not name a lead investor, participating funds, a close date, use of proceeds, founder or CEO commentary, revenue or installation counts, or instrument type. That list of unknowns spans the round's mechanics, its backers, and the company's operating metrics.

Until 1KOMMA5° confirms those details, the $1.35 billion mark reads as a directional signal rather than a settled fact.

Why private valuations drift

Private-market valuations move between announcement and final close. Sellers, buyers, and existing investors reset the number through markups, secondaries, and cap-table cleanups before the round settles. Funds typically treat the announced figure as provisional until the company files investor disclosures.

That's standard practice in late-stage venture. A reported valuation is a snapshot, not a notarized closing statement.

The home-energy cleantech lane

ESG Today frames 1KOMMA5° squarely in the home-energy cleantech lane. That vertical covers residential decarbonization plays—building electrification, distributed renewables, and integrated home-energy management platforms.

Capital has flowed into the category as European residential buildings face tightening emissions caps. The unicorn club in this segment remains small relative to U.S. software peers.

What to watch

Three disclosures will determine whether the $1.35 billion tag holds. Investors want a complete roster. They want a confirmed close date. They want a use-of-proceeds statement from management.

Founder commentary, when it surfaces, will likely clarify the round's size relative to the company's revenue base. That ratio will tell readers whether €70 million is a step or a destination.

The so-what

For European cleantech watchers, 1KOMMA5° now ranks among the leading privately held residential-energy names that have crossed $1 billion in valuation. Whether the €70 million raise is a standalone event or a stepping stone to a larger Series C or D inside the next 12 months remains open.

The next round of reporting—when it lands—will frame the answer.
