Founded in 2011, Tokyo-based Mujin provides MujinOS, a software platform that unifies robot vision, motion planning and real-time digital twin technology to automate complex manufacturing and logistics tasks. The system controls mixed fleets of robotic arms, AGVs and storage robots under a single architecture, eliminating custom system integration and accelerating deployment. Current applications span depalletizing, palletizing, piece picking, truck unloading, warehouse execution and fleet management. With the new funding, the company will pivot from project-based integration to a more scalable product-led model centered on MujinOS, expand its product lineup and accelerate global rollout in Europe and North America. Resources will also go toward enhancing plant- and warehouse-level digital twins and hiring additional world-class engineers to advance next-generation physical-AI capabilities. Including the latest round, Mujin has raised a cumulative ¥596 billion (≈US$4 billion) in equity and debt financing.

建ロボテック is a construction-focused R&D company founded in 2013 that develops collaborative robots and labor-saving solutions for construction sites, notably the Tomorobo series. Its flagship product is the self-propelled rebar-tying robot “Tomorobo,” deployed to about 20 client companies since 2020 and offered as a robot-dispatch service with over 110 site deployments since 2022. Using feedback from years of on-site deployments, the company has developed a latest version with substantially lower human involvement and plans to commercialize that model. Beyond rebar work, it intends to commercialize additional machine models to reduce burdens for all construction-site workers. The company states its mission as “to create the world’s most people-friendly sites” and is pursuing MET A construction diversity goals in collaboration with partners. Headquartered in Miki, Kagawa Prefecture, the company has raised about ¥600M in total funding to date, including a recent ¥150M Series B via third-party allotment.

Quantenna develops ultra-high performance Wi‑Fi semiconductor and system software solutions for carriers and retail OEMs. The company has shipped tens of millions of Wi‑Fi chipsets that are deployed by tier-one telecom, cable and satellite providers including AT&T, DirecTV, Orange and Telefonica, and by numerous retail OEMs. Earlier this year Quantenna unveiled what it described as the world’s first 10G Wi‑Fi technology for access points, featuring an architecture enabling up to 8x8 MIMO, throughput and capacity up to 10 Gbps, and universal support for MU‑MIMO clients. The company says the 10G Wi‑Fi delivers high capacity and performance while minimizing spectrum usage to maximize geo-capacity. Quantenna will use the newly raised funds to expand its investment in technology and customer success as it scales through accelerating growth. Quantenna is headquartered in Silicon Valley with offices worldwide. Quantenna develops standards-based 802.11n and 802.11ac 4x4 MIMO chipsets that aim to deliver high performance, coverage, and wire-like reliability for whole-home video and other demanding applications. The company positions its 4x4 MIMO chipsets as the only commercially available solution for ultra-high reliability, carrier-grade video distribution in both managed and over-the-top architectures. Its chipsets have been integrated into products from vendors including AirTies, Amper, Datasat Technologies, Gemtek, Motorola, Netgear, Sagemcom, Sigma Designs, Swisscom, Technicolor and Telefónica. Quantenna is pursuing 40- and 28-nanometer process technology for next-generation products and plans to accelerate new product development as it enters new market segments. The company will use funding to expand its engineering and service organizations to support growing deployments worldwide. Quantenna also plans to expand its presence in Russia, including opening a Russian subsidiary and collaborating with local engineering schools. Quantenna Communications is a semiconductor chip maker. Its technology is used to support the deployment of video services to the home. Telefónica Ventures, the investment arm of Telefónica Digital, has made an equity investment in the company. The investment was made so Telefónica can gain access to Quantenna's latest technology. Telefónica is a Spanish broadband and telecom company. The deal positions Quantenna to work with a major operator on home video-service deployments. Quantenna develops semiconductor chips that let consumers wirelessly stream HD video to home devices. Its technology improves data transfer speeds to about 100 megabits per second over 100–150 feet, enabling reliable Netflix and game streaming and multi-room DVR playback. Quantenna's chips are used by Swisscom in Switzerland and the company will sell chips directly to consumers through Netgear. Management is in talks with U.S. service providers and hopes to finalize multiple deals within a year. The company is primarily focused on consumer applications now but plans to explore enterprise opportunities in 2011. Quantenna expects to see "substantial revenue" early next year and has raised more than $80 million to date. Quantenna develops 802.11n-compatible Wi‑Fi radio chipsets that use MIMO 4×4, dynamic digital beam‑forming and wireless channel monitoring to improve signal robustness and throughput. The company reports measured through‑wall performance of 145 Mbps at 60 feet (one wall) and 83 Mbps at 170 feet (six walls), outperforming typical rival solutions. Quantenna plans to move production from a 90‑nanometer process to a more efficient 65‑nanometer process and to get its chips into mass production. The company was founded in 2006, has about 60 employees, and says it will ship its first chips by the end of the year. Management expects to generate several million dollars in revenue in the current year as it begins shipments. To date the startup has raised almost $60 million in prior financings.

Midokura develops network virtualization software focused on the OpenStack ecosystem, offering both an open source edition and a paid enterprise version. The enterprise product (priced at $1,899 per host) includes enterprise support and compatibility with VMware vSphere and the ESXi hypervisor. Its customer roster includes Dell, Blue Jeans Networks, Overstock.com and Puppet. The company plans to expand into the container market by adding support for the Kubernetes container management platform. Midokura says its platform’s multi-platform support (OpenStack, VMware, etc.) is a competitive advantage because enterprises often run multiple technologies. Financially, the company has raised a total of $44 million to date and currently employs about 50 people; management intends to spend the new funding conservatively and does not plan significant headcount expansion. Midokura sells MidoNet, a software-defined networking and network virtualization offering that integrates with popular cloud platforms to simplify cloud networking, scalability, automation, and isolation. The product targets cloud service providers, hosting providers, mobile network operators, large enterprises and smaller companies building private clouds. The company launched a beta of MidoNet in October 2012 and has generated considerable interest since. Midokura has offices in San Francisco, Tokyo, Lausanne and Barcelona and is preparing for broader deployment and expansion. Management is shifting roles as co-founder Tatsuya Kato moves from CEO to chairman and former CTO Dan Mihai Dumitriu becomes CEO. The company plans to use recent funding to hire engineers, deepen the technology, add features, improve management capabilities, and integrate with other technologies and partners. Tokyo-based Midokura's core product is Midonet, a network virtualization control layer that runs on top of existing IP networks and lets users create virtual layer‑2 switches, routers, load balancers and firewalls via a UI or API. Virtual network topology is independent of the physical layer, so virtual machines can be moved across infrastructure while the virtual network follows automatically. Midonet components are described as fault tolerant with no single point of failure and are designed to scale out on commodity hardware, which the company says can reduce infrastructure costs. The platform can be delivered via integration into existing products, as a standalone solution, as NaaS, or through Midostack — Midokura's OpenStack (IaaS/EC2) distribution and primary delivery mechanism. Midostack is currently in a limited beta for pilot projects. The company is expanding aggressively worldwide, with an office in Europe, a San Francisco office slated to open this summer and possible plans for Singapore later in the year, and is actively hiring; it raised $1.3 million in seed funding and is seeking a Series A this year.
