ROMS

What ROMS does

ROMS is a Tokyo-based industrial technology company founded in June 2019 that designs, manufactures, and sells compact automated storage and retrieval systems (AS/RS) and logistics robotics targeting Japan's space-constrained warehouses and labor-scarce fulfillment operations. The company's product portfolio centers on high-density AS/RS systems deployable in footprints as small as 8-100㎡ — materially smaller than the 500㎡+ footprint required by conventional automated warehouses — including the flagship Nano-Fulfillment Center (NFC), the modular Nano-Stream system, the Nano-Sorter high-layer piece sorter, the Robot Picking System, and the Robotics Convenience Store (RCS) for unmanned retail. All hardware, control software (WCS/WES), electrical design, UI, and integration platforms are developed in-house domestically, which the company cites as enabling a 4-6 month order-to-operation timeline.

The technology stack combines proprietary miniaturization design, group-control coordination of cranes, AGVs, and shuttles, AI vision systems capable of picking unfamiliar objects without prior image registration (up to 1,000 picks/hour), and an AI-powered Packing Assist SaaS that recommends optimal box sizes using 3D product dimensions. Standard API integrations connect the systems to Japan's dominant WMS platforms (iWMS X5, LOGILESS, logiec). Named customers include NTT Logicso, Chikuta Express/Seino Group, KDDI Corporation, and a broader roster of mid-market 3PL and logistics operators.

ROMS monetizes through direct hardware sales and leasing of automation systems, pay-per-use SaaS subscriptions for Packing Assist AI (4-5 yen per transaction), and professional services for system introduction and operations consulting. The company sells primarily through direct enterprise field sales supported by the Heiwajima Lab demonstration showroom in Tokyo, major trade show participation, and co-marketing partnerships with WMS integrators. As of September 2025, ROMS had raised approximately ¥1.3 billion (~$8.8M) in cumulative venture funding led by DNX Ventures, and has expanded internationally with a US subsidiary in San Mateo, California.

Direct peers

• Mujin: Japanese warehouse robotics company providing intelligent automation for logistics operations. Highly comparable — same geography, similar customer segments (Japanese 3PLs, manufacturers), and overlapping product scope (AS/RS + robotic picking). Mujin is larger and more established, making it the most relevant direct peer.
• Geek+: Global Chinese warehouse robotics company offering AMRs, goods-to-person systems, and sortation solutions. Direct competitor in AS/RS-style automation with overlapping product categories (mobile robots, sorting, picking) and global e-commerce/3PL customer base.
• AutoStore: Norwegian cube-based storage automation company with global deployments. Highly comparable product concept (high-density automated storage), publicly listed, and competing for the same space-efficient warehouse automation use cases that ROMS addresses — though at a larger facility scale.
• Exotec: French warehouse robotics company offering the Skypod goods-to-person system with compact, scalable storage. Strong product and business-model comparability to ROMS's Nano-Fulfillment Center approach — modular, scalable AS/RS for e-commerce and 3PL fulfillment.
• Locus Robotics: US-based AMR provider focused on warehouse piece-picking alongside human workers. Comparable in addressing labor-shortage-driven picking automation and serving 3PL/retail customers, though with a different mechanical approach (collaborative AMRs vs. crane/AGV-based AS/RS).
• Hai Robotics: Chinese warehouse automation company offering ACR (Autonomous Case-handling Robot) systems for high-density storage. Overlapping product category and comparable focus on space-efficient AS/RS for e-commerce and 3PL operations in Asia.

Broad incumbents

• Symbotic: US-based publicly traded warehouse automation company focused on large-scale grocery and retail distribution centers. Overlapping capability set (automated storage, picking, sortation) but oriented toward much larger enterprise deployments than ROMS's small/medium facility focus.
• Swisslog: Established German warehouse automation provider (owned by KUKA) offering AS/RS, conveyors, and software for large distribution centers. Comparable AS/RS capability but serves broader, larger-scale deployments rather than ROMS's small-footprint niche.
• Dematic: Global warehouse automation incumbent (owned by Kion Group) offering integrated AS/RS, sortation, and WMS solutions. Direct technology overlap but a much broader, larger-facility orientation than ROMS's small/medium Japanese warehouse focus.

Emerging players

• Takeoff: US-based micro-fulfillment company deploying automated small-footprint fulfillment centers for grocery e-commerce. Comparable vision of compact, automated fulfillment for labor-constrained retail, with partial product overlap (Nano-Store/RCS-like unmanned retail solutions).
