  • New Space Intelligence

    Participated · Series A · Apr 2026

    New Space Intelligence offers a “Satellite Data Pipeline” that automates selection, integration (harmonization), analysis, and provisioning of heterogeneous satellite data for applications like infrastructure monitoring and disaster analysis. Its core capabilities include calibration using ground-based mirror reflectors combined with AI-driven image quality evaluation and correction, plus harmonization technology to combine data from multiple satellites for higher-frequency observation and continuity. The company targets public and industrial customers across use cases such as railways, roads, power infrastructure monitoring, disaster response, illegal dumping detection, and land use analysis. Following its ¥430 million Series A, the firm plans to expand existing services, build new GLI-based applications, strengthen product development, and grow sales, marketing, and hiring. It also intends to expand geographically into Asia, North America, and Africa. New Space Intelligence was selected for JAXA’s Space Strategy Fund Phase 2 project and will develop sensor evaluation and calibration methods under that program through September 2030.

  • TORIHADA

    Participated · Series A · Mar 2026

    TORIHADA positions itself as a creator-DX company building products to accelerate the creator economy, including the FANME platform for fan engagement and monetization and a proprietary creator database called Pythagoras used for short-video marketing to advertisers. Its subsidiary PPP STUDIO supports and manages creators, reporting over 2,000 affiliated or partnered creator groups and a combined follower count of 540 million. The company is actively expanding into TikTok Shop and live-commerce, investing in in-house commerce accounts and unique product development, and is developing an AI-driven tool provisionally named Auto Short Movie for automated commerce-video creation. TORIHADA also plans new initiatives such as a label to support creators' music and game streaming and an educational TORIHADA ACADEMY to share live-commerce and AI know-how. Financially, TORIHADA raised ¥1.5 billion in a Series A comprised of equity and debt to fund these strategic priorities. The company is headquartered in Shibuya, Tokyo and is led by CEO Eiryo Wakai, under a mission to become Japan's leading creator-economy company.

  • Pocket Sign

    Participated · Series B · Oct 2025

    Pocket Sign centers its offering on the municipal super app "PocketSign," which lets residents obtain copies of residence certificates, receive disaster alerts, and complete multiple government procedures in one place. The company supplements the app with "PocketSign MynaConnect," a gateway that safely links external services to the government’s My Number Portal API, and "PocketSign Platform," a mini-app development environment. Its core technology embeds Japan’s Public Key Infrastructure (JPKI) into smartphones, allowing online proof-of-identity and meeting the high security standards required by both public and private sectors. Developers can integrate this capability quickly through Pocket Sign’s proprietary SDK. The service is already being rolled out by municipalities across Japan, and the firm now aims to extend its digital-identity infrastructure to the residential market in partnership with Sekisui House Group. Funds will be used to expand municipal features and build housing-focused identity and contract workflows, positioning Pocket Sign as a trust layer that bridges public and private services. To date, the company has raised a total of ¥1.4 billion in funding.

  • Shippio

    Participated · Series C · Oct 2025

    Shippio operates a cloud-native platform designed to digitalize and simplify international logistics workflows for shippers, forwarders, and other supply-chain stakeholders. Its software automatically updates shipment status, quotations, and orders while centralizing trade documents, invoices, and communication in one interface. Integrated cargo tracking and data analytics help customers gain real-time visibility and optimize decision-making. The company positions itself as a digital transformation layer for global trade, aiming to connect fragmented logistics processes end-to-end. Following its Series C round, Shippio has amassed roughly ¥7 billion in total funding. Management intends to use the new capital to accelerate product development, pursue strategic M&A opportunities, and grow headcount to about 300 employees. The firm’s long-term vision is to advance international logistics through continuous digital innovation.

  • ByWill

    Participated · Series B · Oct 2025

    Headquartered in Tokyo, ByWill supports companies and local governments across Japan in achieving carbon neutrality by turning their decarbonization efforts into monetizable carbon credits, primarily through the J-Credit scheme. Its core offerings span environmental-value creation support (credit generation), carbon-credit brokerage, decarbonization consulting and related brand-building services. The company positions itself as a co-creator that transforms green transformation (GX) from a compliance cost into a growth driver, aiming to create a virtuous cycle between environmental and economic value. Since announcing the first close of its Series B in July 2025, ByWill has continued to grow, expanding its nationwide partner network and increasing the number of J-Credit creation support contracts, though no specific operating metrics were disclosed. Demand is buoyed by a strengthening domestic and international carbon-credit market, including the forthcoming GX-ETS Phase 2 in 2026. The newly raised capital will be directed toward improving the productivity of its environmental-value services, expanding credit-creation geographies and methodologies, and hiring talent to sustain rapid growth. Cumulative funding now stands at ¥3 billion, giving the company additional resources to accelerate its mission of making GX something organizations “want to do” rather than “have to do.”
