Investment portfolio

  • 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.

  • Volund Manufacturing

    Participated · Seed · Jun 2026

    Volund Manufacturing is a manufacturing company led by Eric Hostetler that recently completed a $12 million Seed financing. Coverage of the raise appeared via Marlinspike, which celebrated Volund as part of its portfolio. Public reporting on the company did not include specifics about its products, markets, or operating metrics. The articles also did not disclose the company’s founding year, location, prior funding history, or detailed plans for the newly raised capital. The available public messaging around the raise included celebratory language such as “Rearm and Rebuild!” but offered no further operational or financial detail.

  • Layup Parts

    Led · Series A · Jun 2026

    Layup Parts was founded to streamline production and ordering of custom composite parts such as carbon-fiber and fiberglass components. The company has rapidly prototyped and produced parts for customers in motorsports, design studios, consumer goods (including pickleball paddles), and aerospace and defense primes and startups. It has cut turnaround time between receiving customer data and manufacturing parts from weeks to hours in some cases. The startup employed roughly 60 people at the time of the Series A and is based in Huntington Beach, California. Layup Parts used most of its seed funding on capital expenditures and plans to use the new capital to hire more staff and move into a larger facility.

  • Armada

    Participated · Series B · May 2026

    Armada builds and delivers modular AI infrastructure — including Galleon manufacturing systems, Leviathan megawatt-scale modular data centers, and Triton portable units — for high-density training, inference, sovereign neo-cloud and multi-tenant compute environments. The company has documented rapid commercial traction, reporting 540% customer bookings growth in FY25–26 and a 2000% bookings increase in Q1 FY27 year-over-year. Armada has supported defense and commercial deployments, including a rapid Triton field deployment for a defense ally, a U.S. Navy edge deployment during a multinational exercise, a WinDC renewable-energy-backed AI factory deployment in Australia, and trials with Aker BP for offshore rig use. Armada is expanding manufacturing capacity with Galleon Forge One, a planned up-to-400,000-square-foot factory in Arizona expected to create about 500 jobs, enabled by a framework agreement and investment from Johnson Controls. The company has built an ecosystem and marketplace with partners including Microsoft, NVIDIA, Palantir and Dell Technologies to accelerate customer deployments and maintain control over sensitive data and models. Armada has raised capital totaling nearly half a billion dollars to date and is using that funding to scale production, meet accelerating global demand, and support new initiatives.

  • Chariot Defense

    Participated · Series A · Feb 2026

    Chariot Defense develops the Amphora family of hybrid power systems, a modular hardware-plus-software platform that senses, prioritizes, and routes electric power across battlefield assets in real time. The technology lets warfighters run radios, drones, sensors, and other gear without interruption, detectable signature, or wasted capacity. Since emerging from stealth in July 2025, the company has secured sales and contracts with the U.S. Army, the Defense Innovation Unit’s Project GI, and several commercial customers, generating revenue within its first year of operations. Fresh capital will be used to ramp production, build an operating system for power command and control, and aggressively hire mechanical, electrical, and software engineers. Management frames power as the next critical constraint in defense and positions Amphora as a combat multiplier that extends operational independence. Founded in 2024 and backed by prominent national-security investors, Chariot has raised $41 million to date, including the newly announced Series A.
