1Komma5° invests in Marunouchi Innovation Partners

Deal terms as reported in the coverage below.

Decision brief

What changed

1Komma5° raised €70 million from existing and new investors, including newcomer Marunouchi Innovation Partners, rather than moving ahead with an IPO. The company said it is valued at about $1.35 billion (€1.2 billion) and plans to invest more than €100 million next year in its Heartbeat AI home energy management system.

Why it matters

This financing gives 1Komma5° additional capital to keep expanding its AI-based home energy control platform without relying on public markets now. For business leaders, the combination of a new strategic investor, a stated billion-euro valuation, and planned heavy spending on Heartbeat AI signals continued competition and investment in AI-enabled residential energy management while the company keeps IPO timing flexible.

Evidence

The provided coverage consists of one report from Trending Topics EU stating that 1Komma5° raised €70 million, included Marunouchi Innovation Partners as a new investor, held its IPO, and plans to invest more than €100 million in Heartbeat AI next year. Because the brief relies on a single cited outlet and no second independent report is provided here, corroboration is limited.

What remains uncertain

The coverage does not specify MIP’s stake, governance rights, or whether the investment changes 1Komma5°'s commercial strategy beyond providing capital. It also does not verify how much of the planned €100 million Heartbeat AI investment is fully funded by this round versus expected from future operating performance or additional financing.

Monitor next

Watch for 1Komma5°'s next disclosure on Heartbeat AI deployment metrics or funding plans, especially any update linking next year's performance to renewed IPO timing.
