- Fabri
Participated · Equity · Jun 2026
Fabri, founded in 2022 as an MIT spinout and led by CEO Steven Davis, builds automated foundries that use 3D-printed wax molds, robotics, and bespoke software and machine learning to reduce labor and rework in investment casting. The company began with aluminum parts and has expanded into copper and steel alloys, and it reports shipping parts to customers including Lockheed Martin and RTX. Fabri has collaborated with NASA on casting research and currently operates an R&D foundry capable of producing hundreds to maybe thousands of parts. Management plans to scale capacity by opening additional foundries — targeting a second facility to reach full production by 2027 and aiming to open a new foundry each year. Financially, Fabri has raised $13.5M total (a $5M seed in Dec 2024 plus prior debt and equity) and is preparing for a Series A in the next three to six months.
- OurSky
Led · Series A · May 2026
OurSky merged with PlaneWave Instruments in February 2025 to create Observable Space, a vertically integrated hardware-and-software space company building laser communications ground stations, ground-based sensing systems, and in-space optical payloads. Observable Space operates facilities in Los Angeles and Michigan and plans to scale manufacturing in Detroit as it raises production capacity. The company announced a $90M Series A to support production growth and international expansion. It has also secured an IDIQ contract from the U.S. Space Force worth up to $94M, with $22M in initial task orders awarded. Observable Space plans to send its compact Iguana in-space imager into orbit this year aboard an Apex Space satellite bus; the system is offered to customers with about eight weeks’ lead time. Leadership has stated the merged company aims to provide real-time orbital insights by combining hardware and software into a single offering.
- Darkhive
Led · Series B · May 2026
Darkhive, founded and led by John Goodson, is a defense-focused technology company based in San Antonio that aims to deliver cutting-edge technology to U.S. defense customers. The company runs programs with the U.S. Air Force, the Defense Innovation Unit, and the Air Force Research Laboratory, and was selected by the Pentagon to lead a $49.7M APFIT program. Darkhive has progressed from angel-backed pre-seed support in 2022 to raising a $30M Series B led by RTX ventures. Its growth has been characterized by winning national contracts and scaling operations in San Antonio. The company emphasizes retaining and expanding defense-related innovation locally rather than relocating to other innovation hubs.
- Reliable Robotics Corporation
Participated · Equity · Apr 2026
Reliable Robotics develops the Reliable Autonomy System (RAS), an FAA-certifiable autonomy stack designed to enable fully automated aircraft operations and prevent the leading causes of aviation accidents. The company says RAS is built to integrate with certified aircraft and existing aviation infrastructure without changes to the National Airspace System. Reliable has secured commitments for over 200 systems from commercial and military customers, been selected for the Department of Transportation’s eIPP advanced aviation pilot program, and holds a contract to provide automated air cargo operations for the U.S. Air Force. The business has been advancing FAA certification—having had its certification plans and means of compliance accepted—and is delivering required compliance materials under the FAA-agreed plan. Since its last financing the company has nearly tripled its workforce and plans to use the new $160M to expand production facilities, grow headcount, and accelerate deployment toward autonomous cargo operations in 2026. The company is headquartered in Mountain View, California and maintains a distributed global workforce.
- Hermeus
Participated · Series C · Apr 2026
Hermeus develops hypersonic unmanned aircraft and pursues rapid prototyping and flight testing to accelerate aircraft maturation. The company has flown multiple demonstrators, including a recent demonstrator about the size of an F-16 and an earlier, smaller demonstrator, and is working on a third aircraft iteration aimed at supersonic performance. Hermeus shifted from developing an in-house engine to modifying Pratt & Whitney’s F100 engine via a relationship with RTX/Pratt & Whitney to speed testing and reduce technical risk. The startup is expanding manufacturing capabilities and hiring—its staff is approaching roughly 300 employees—to support hardware production and iterative builds. Financially, the company recently raised $200 million in equity and $150 million in debt, valuing it at $1 billion, to fund growth and continued flight-test programs.
