|---|---|---|---|---|---|
| Jan 2026 | Series B | Johnson Controls (lead) | $65M | $665M | Accelsius, a subsidiary of Innventure established in 2022, develops two-phase direct-to-chip liquid cooling technology originally acquired from Nokia Bell Labs, targeting high-performance computing and AI data centers with products like the NeuCool platform and MR250 Coolant Distribution Unit, promising 35% opex savings over single-phase solutions. Johnson Controls led a $65 million Series B funding round closed in January 2026, comprising an initial ~$25 million investment in October 2025 and an additional ~$40 million Series B-1 from Johnson Controls and Legrand in early January 2026, to expand the Austin production facility, accelerate global rollout, and scale for gigawatt-class AI factories. The $40 million tranche was explicitly based on a company valuation of approximately $665 million, with units priced at $36.4877, providing a market-based benchmark amid surging demand for efficient cooling amid AI-driven thermal challenges. Johnson Controls brings expertise in thermal management and data center innovations like the YORK YVAM chiller, while Legrand contributes power distribution and rack infrastructure, enhancing Accelsius' strategic positioning as an NVIDIA Inception member developing high-capacity thermal reference designs. |
| Oct 2025 | Strategic investment | Johnson Controls (lead) | $25M | $665M | Accelsius, a subsidiary of Innventure established in 2022 after acquiring two-phase direct-to-chip liquid cooling technology from Nokia Bell Labs, develops the NeuCool platform for high-efficiency cooling in AI data centers and high-performance computing. The technology uses non-conductive fluids to enable up to 35% opex savings over single-phase solutions and supports extreme thermal densities in AI factories, recently deployed in a 300MW campus for DarkNX in Ontario. Accelsius differentiates in a competitive landscape including Iceotope and JetCool through its two-phase immersion approach targeting gigawatt-scale facilities. Accelsius raised $65 million in a Series B funding round structured in tranches, starting with $25 million from Johnson Controls in October 2025, followed by a $40 million close on December 29, 2025, comprising $10 million from Johnson Controls and $30 million from Legrand. Investments were made via convertible Series B-1 units priced at approximately $36.49 per unit, bringing cumulative funding to around $89 million after a $24 million Series A in November 2024 led by Innventure. The $40 million tranche was explicitly based on a valuation of approximately $665 million for Accelsius. Strategic investors Johnson Controls, a leader in smart building and data center solutions like YORK chillers, and Legrand, specializing in power distribution and connectivity, provide distribution channels, technical synergies, and credibility for scaling production. Funds will expand Accelsius' Austin facility, develop NVIDIA-aligned thermal reference designs, and support general purposes while reducing Innventure's convertible debentures on Accelsius. |
| Nov 2024 | Series A | Innventure (lead) | $24M | - | Accelsius is an Austin-based data center cooling technology company founded by Innventure in 2022, specializing in NeuCool, a direct-to-chip liquid cooling system designed to reduce cooling costs by up to 50% without heavy water usage, targeting high-power AI computations that demand efficient thermal management. The company raised $24 million in a Series A funding round in November 2024, primarily from Innventure, to support research, team expansion, and international growth, with plans to double its approximately 75 employees focused on engineering, R&D, sales, and operations. Earlier in 2024, Accelsius partnered with the University of Texas' Texas Advanced Computing Center for a proof-of-concept on the Vista supercomputer cooling NVIDIA GH100 Grace Hopper Superchips. A ~$665 million valuation was stated for a $40 million Series B-1 closing on December 29, 2025, involving Legrand ($30 million) and Johnson Controls ($10 million), following a prior $25 million from Johnson Controls in October 2025, bringing cumulative funding to ~$89 million by early 2026. Series B-1 units converted at $36.4877 per unit, with Legrand gaining board seats and rights. Funds supported production scaling, global expansion, and gigawatt-scale solutions amid AI infrastructure demands. Traction includes deployments like NeuCool across DarkNX’s 300 MW Ontario campus and proof-of-concept sales contributing $0.5 million to Innventure’s Q3 2025 revenue, though the parent reported a $34.7 million net loss. Accelsius competes with players like Schneider Electric in direct-to-chip cooling, benefiting from strategic alliances with Johnson Controls and Legrand for potential bundled offerings in hyperscale and edge data centers. Innventure, as owner-operator, aims for $1 billion enterprise value through such ventures spun from multinational technologies. |
