Founded in July 2024, Qubitcore builds on OIST research to integrate ion-trap quantum processors with micro optical resonators to enable high‑efficiency photon–qubit interfaces and multi-module optical connections. The company aims to realize fault-tolerant quantum computers via a distributed quantum computing architecture and holds an exclusive license with OIST signed in July 2025. Its roadmap targets a cloud-accessible quantum computer prototype operating at OIST in 2026, an Early‑FTQC with error‑correction capabilities by 2028, and a second‑generation multi‑QPU optically connected system by 2029. Qubitcore has strengthened its financial position through a ¥1.53 billion seed round led by SBI Investment, following a pre-seed in January 2025, and plans to deploy funds into R&D, partner/validation activities, and hiring.

MUSE builds and sells Armo, a store robot that automates in-store shelf stocking, EC picking and transports between backroom and shelves. Armo also scans shelf conditions and stores that data in MUSE’s Eureka Platform for real-time shelf visibility, out-of-stock detection, planogram drift and price checks. The robot supports customer-guidance features to lead shoppers to items and accepts modular extension units — e.g., transport, imaging and guidance — to serve multiple store tasks. MUSE says the system both raises staff productivity and creates a database that can be used for marketing and operational optimization. The company plans to accelerate Armo’s service deployment using the newly raised capital and has moved from a December 2023 verification with Belc to normal operations at two Saitama stores from June. MUSE was founded in April 2022 and previously closed a seed round in October 2022.

TieUps plans to use recent funding to launch lit.link’s global business, expand WeClip’s functionality, and strengthen hiring. The company has stated a new corporate mission to “evolve communication and create valuable connections” and has renewed its corporate website to communicate that mission.

WeClip launched its beta in October 2021 and hosts more than 1,000 communities; an iOS app and business features were planned for release in 2022. The company frames its offering as Fan Relationship Management (FRM), aiming to convert single page views into long-term, enthusiastic fans. TieUps was founded on April 30, 2020 in Shibuya, Tokyo, and emphasizes feature development, hiring, and strengthening internal operations as strategic priorities. The recent seed financing will be directed toward product feature expansion, recruitment, and organizational growth.
