• Nexusbe

  Participated · Series C · Jul 2026

  Founded in 2015, Nexusbe designs ALD equipment and proprietary gas-injector technology that enables nanometer-scale precise thin-film deposition. Its ALD systems are applied across semiconductors, displays, high-efficiency solar cells and secondary-battery electrode and separator coatings, and the company supplies equipment to more than 70 universities and research institutes. Nexusbe established a sales subsidiary in China last year and is expanding local commercial efforts in response to the Chinese solar-cell market. The company reported successive institutional financings since 2021 and has a cumulative funding total of 290억 won following the completed Series C. Management plans to accelerate ALD technology development and scale mass-production deployment, and is preparing for a KOSDAQ IPO with joint lead managers already appointed.

• Gaianixx

  Participated · Series C · Mar 2026

  Gaianixx is a University of Tokyo spin-out engaged in the research, development, manufacturing and sale of a proprietary interlayer that is inserted between a substrate and semiconductor film to relax lattice mismatch and yield high-quality single-crystal compound semiconductors. Its technology targets applications ranging from power semiconductors and LEDs to next-generation sensors and communication devices. Since its Series B round, the company has progressed from pure R&D into commercialization; two partner companies have already shifted to device development using Gaianixx materials, and roughly 40 domestic and international device makers are in active joint-development or evaluation discussions. The firm operates a Yamanashi Technical Center and is building a dedicated pilot production line. Gaianixx holds 12 granted patents with a further 87 filings in process. Cumulative funding now totals about ¥3.85 billion, which supports global expansion across North America, Europe and Asia as well as key hiring.

• EX-Fusion

  Participated · Series A · Oct 2025

  EX-Fusion is building a commercial laser nuclear fusion energy platform aimed at delivering carbon-free, domestically producible power. The company is integrating optical control, continuous target supply, and high-output laser technologies to create a reactor capable of sustaining ten fusion reactions per second, with a milestone of one hour of continuous neutron generation targeted for fiscal 2027. Its technology stack is expected to extend beyond energy into laser processing, medical, and space applications, leveraging the same high-precision photonics capabilities. EX-Fusion is strengthening collaborations with national research institutes, universities, and large corporations to build an ecosystem for social deployment of its fusion solutions. The firm began pursuing laser fusion in 2021 and has raised ¥3 billion in Series A funding to date, contributing to a total of ¥6 billion since inception. No revenue or customer metrics have been disclosed, underscoring the company’s early R&D stage.

• Addionics

  Participated · Series A · Jan 2022

  Addionics produces textured, three-dimensional copper and aluminum foil current collectors for lithium-ion batteries, using electro-deposition for copper and electroetching for aluminum. Its foils feature tiny holes and undulating peaks and valleys that increase contact between the foil and active material. The company says the design improves battery performance and efficiency and can potentially double battery lifespan, and that the collectors can work with a wide range of chemistries. Addionics plans to tailor collectors to different chemistries in the future to extract additional performance. The Israel- and U.K.-based startup recently raised a $39 million Series B to accelerate delivery of its current collectors and to explore new markets and geographies. Earlier this year it announced plans to build a $400 million factory in the U.S. and said it has letters of intent from U.S. automakers. Addionics develops patented Smart 3D Electrode architecture and a scalable electrode fabrication process that replaces traditional 2D layered electrodes, aiming to increase energy density, power, safety and lifetime without raising cost. Its drop-in solution is compatible with existing battery manufacturing lines and is paired with a proprietary AI algorithm to accelerate and optimize electrode design for varied applications. The company targets electric vehicles initially and is collaborating with automotive OEMs and suppliers in the U.S. and Europe to integrate with NMC, LFP, silicon, lithium polymer and solid-state chemistries. Addionics plans to commercialize by 2024 and will use funding to advance product development, expand the team, and increase activity in the U.S. and Germany. The company also highlights applications beyond EVs, including consumer electronics, stationary storage, aviation, defense and medical devices. Addionics has developed a scalable, patent‑protected “smart 3D structure” that redesigns battery architecture via 3D metal fabrication to reduce internal resistance and improve mechanical longevity and thermal stability. The company’s approach is chemistry‑agnostic, designed to enhance existing and future battery chemistries rather than replace them. Addionics says its technology can increase EV mileage, improve safety, and reduce cost and charging time, and could be applied to consumer electronics, medical devices, grid storage, drones, and more. Commercial traction is early: the company is working with an unnamed tier‑1 American automotive company on a proof‑of‑concept and testing Addionics cells in vehicles. Management aims to secure 3–4 major collaborations with world‑leading OEMs over the next year. Financially, the company has raised $6M in funding, which includes a $2.5M grant awarded through the European Union’s Horizon2020 program.
