The company is conducting safety verification using formal methods and has demonstrated roughly 500 km of non-steering driving on highways including toll-booth passages. From 2024 demonstrations, it has transported cargo for over 50 partner companies, and commercial operations that began July 1 last year have expanded to 23 customer companies. T2 plans to deploy Level 4 trunk transportation services from fiscal year 2027 and is building driver-switching hubs called “Transgate” near Ayase, Kobe, and Nishinomiya by spring 2026. Financially, the company has raised over ¥16.5 billion to date, including the ¥5 billion first close of its Series B, and says it will use the new proceeds to accelerate its business and technology development toward Level 4.
- Ms.Engineer
Participated · Series A · Oct 2025
Ms.Engineer operates a proprietary eight-month online bootcamp that upskills women into advanced AI/IT talent, boasting a 95 % graduation rate and over 90 % job-placement rate. The company’s mission is to close Japan’s gender wage gap by enabling economic independence for women, particularly in regional areas. Beyond education, it deploys its graduates in “DAIVE,” a near-shore, fully remote AI development team that supports digital transformation projects nationwide. The newly raised capital will accelerate the nationwide rollout of its training program, strengthen the DAIVE development business, and fund additional engineering and business hires. Ms.Engineer also develops and offers AI agent products, expanding its revenue streams beyond education services. Following the latest financing, the company’s cumulative funding now totals roughly ¥650 million, giving it additional runway for growth initiatives. While revenue figures were not disclosed, the strong bootcamp performance metrics highlight early traction and market demand.
- Enechain
Participated · Series B · Apr 2024
enechain provides eSquare Live, an online marketplace where market participants can buy and sell electricity, fuels, and environmental value products. The platform has handled more than ¥3 trn in cumulative wholesale electricity transactions, and its screen‐based trading volume via eSquare Live grew more than 25× year-on-year. To reduce counterparty and settlement risk, the company runs joint ventures eClear (with MUFG Bank) for power-trade clearing and eXstend (with Sumitomo Mitsui Financial Group) for fuel-price hedging. Following its latest financing, enechain’s paid-in capital has reached roughly ¥10 bn and group-wide funding now totals several hundred billion yen. The new capital will be used to upgrade eSquare Live to global-class UX and reliability standards, aggregate additional products and data, deepen ecosystem integrations, and embed advanced AI capabilities through a newly created AI lab. The company will also invest heavily in cybersecurity and consider M&A to accelerate energy-sector digital transformation.
- Sharing Energy
Participated · Series B · Apr 2024
Sharing Energy operates “Share Denki,” a third-party ownership PPA model that lets homeowners install solar panels without any initial expenditure, with the company handling ownership and maintenance while selling the generated power on long-term contracts. It partners with more than 1,800 builders and other partners nationwide and has received over 24,000 contract applications to date. Beyond the core residential offering, the firm also markets “Share Denki for Biz” for commercial users, “Share Denki FLAT” for zero-upfront energy-saving and storage equipment, and is developing energy-management services. Rising demand for residential solar—driven by new efficiency standards and municipal installation mandates—is expanding the company’s addressable market. Sharing Energy plans to use its latest capital to enhance service quality, accelerate deployment, and design new services and financing schemes so distributed energy can function as critical infrastructure. The firm has previously tapped project finance in 2024 and 2025 and now seeks a more flexible, scalable funding base. Including the Series C first close, cumulative funding stands at ¥26.79 billion.
