  LSAS Tec

  LSAS Tec is a specialized provider of software and engineering services focused on mission simulation and operational analysis across the land, sea, air, and space domains. The company was established in April 2009 in Japan as a spin-off from a technology trading company's space division, founded by three experienced engineers and business professionals. Its origin lies in serving as the Japanese partner for Ansys Government Initiatives (AGI), where for over 15 years its team distributed and provided technical support for AGI's Digital Mission Engineering tools, including the Systems Tool Kit (STK) and Orbit Determination Tool Kit (ODTK). Evolving from a reseller and support provider, LSAS Tec now develops its own proprietary commercial off-the-shelf (COTS) software and solutions. These offerings extend the capabilities of core Ansys tools, focusing on workflow automation and satellite operations solutions tailored to client needs. The business model encompasses the sale of partner products, licensing of its own software, and providing expert engineering services, training, and technical support. Its clientele ranges from commercial space startups and private venture companies to large systems integrators and government agencies, including JAXA and the Japanese Ministry of Defense. The company's product portfolio is built around the Ansys Digital Mission Engineering suite, which enables physics-based modeling and simulation for complex systems. LSAS Tec enhances this foundation with its own developments that integrate advanced algorithms and data analytics to streamline mission-critical operations such as flight dynamics and space domain awareness. While maintaining a strong focus on the growing space sector, the company supports all operational domains, true to its name's acronym (Land, Sea, Air, and Space). Headquartered in Japan, LSAS Tec has expanded its operations globally, with an office in the USA to serve clients worldwide.

  LSVT Global, Inc.

  Health

  LSVT Global, Inc. provides evidence-based physical, occupational, and speech-language therapy programs for individuals with neurological conditions, primarily Parkinson's disease. The company's core offerings are the Lee Silverman Voice Treatment (LSVT) LOUD and LSVT BIG programs. LSVT LOUD is a speech therapy protocol designed to improve vocal loudness, articulation, and overall communication. LSVT BIG applies similar principles to physical and occupational therapy, focusing on training larger amplitude movements to improve mobility, balance, and activities of daily living. This led to the creation of the LSVT LOUD protocol. LSVT Global's business model is centered on training and certifying clinicians—speech, physical, and occupational therapists—to deliver the LSVT LOUD and LSVT BIG treatments. The company offers online, virtual live, and in-person certification courses. Once certified, clinicians are listed in a public directory. The treatments follow a standardized, intensive protocol, typically involving 16 one-hour sessions over four weeks. The company also develops and sells related products, such as the FDA-cleared LSVT LOUD Companion software to assist with therapy, and offers a subscription-based virtual exercise platform called LSVT for LIFE for program graduates to maintain their progress.

  LunaSonde

  Space

  The company's name, Latin for "moon explorer," reflects its long-term vision of applying its technology to explore resources beyond Earth, such as on the Moon and asteroids. Lunasonde is developing a satellite constellation equipped with proprietary low-frequency synthetic aperture radar (SubSAR) technology to create three-dimensional maps of the subsurface, reaching depths of up to two kilometers. This technology is designed to detect underground resources like water aquifers and mineral deposits remotely. The company's technical approach involves miniaturizing low-frequency radar, which traditionally requires very large antennas, to fit on small satellites. After a period of intensive research and development, the company has undertaken several test flights on SpaceX rideshare missions and plans to launch its first full-tech 6U satellite, named San Xavier. The firm primarily targets the mining and water resource management sectors. For mineral exploration, Lunasonde operates on a royalty-based business model, partnering with mining companies to identify new deposits and taking a share of the long-term value of the discovered resources, a common arrangement in the mining industry. In the water sector, the company aims to offer data services on a subscription basis, providing four-dimensional data that tracks changes in water resources over time. This service has applications for monitoring water scarcity, discovering untapped fossil aquifers, and potentially contributing to humanitarian efforts. Lunasonde also identifies the defense sector as a potential market for applications like detecting underground facilities. The company has received non-dilutive funding from the National Science Foundation and has established partnerships with entities like AWS for data processing and Exolaunch for satellite deployment.

  Lunewave

  Transportation

  Lunewave operates at the forefront of sensor technology, specializing in the development and production of advanced radar and antenna systems for a diverse set of industries including automotive, telecommunications, aerospace, and robotics. The founding team combines deep technical expertise with extensive business experience. Min Liang, VP of Technology, contributes over a decade of experience in radar engineering and 3D printing.The company's core business revolves around its proprietary Luneburg lens antenna technology. This technology, adapted from a concept developed in the 1940s, utilizes a spherical lens that is 3D printed, a manufacturing method ideal for its complex structure of over 6,500 uniquely designed chambers in a device smaller than a golf ball. This design enables the creation of radar sensors that offer a panoramic, 360-degree field of view with high resolution, a significant shift from the 'tunnel vision' of traditional planar phased array antennas. The primary product is an automotive radar sensor system operating in the 76-81 GHz band. It boasts a detection range of over 300 meters and can maintain performance at large scan angles, even in adverse weather conditions. This allows a few of Lunewave's sensors to replace the 16 to 20 traditional radar sensors often required for autonomous vehicles, thereby reducing complexity and cost.Lunewave's business model appears to be centered on supplying these high-performance sensors and custom-made antennas to original equipment manufacturers (OEMs) and Tier 1 suppliers in its target markets. For the automotive sector, the technology is positioned as the 'eyes' for vehicles, supporting applications from advanced driver-assistance systems (ADAS) to fully autonomous driving (L5). Beyond automotive, the antennas are suitable for 5G telecommunications and satellite communications. The company has secured significant financial backing to fuel its development and commercialization efforts. It has raised a total of $10.8 million through multiple funding rounds, including a $7 million Series A in November 2020 led by FM Capital. Other notable investors include BMW i Ventures, Baidu Ventures, and Proeza Ventures, reflecting strong industry confidence in its technology. Lunewave has also received grants from the National Science Foundation's SBIR program and is involved in development projects with the U.S. Army.
