  • Atlas Motion

    Participated · Seed · Aug 2026

    Atlas Motion designs and develops specialized Brushless DC (BLDC) motors and high-power-density actuators engineered for defense platforms. The company prototypes and designs hardware in Long Beach and mass-produces systems out of a facility in the Philippines. After emerging from stealth, Atlas Motion raised $11.5M to support manufacturing expansion and operational growth. Planned uses of the capital include opening a second manufacturing plant in the Philippines, building its “Vector” AI production line orchestration software, expanding headcount to roughly 60 employees, and establishing a dedicated U.S. facility to serve domestic defense customers. The business was founded and is led by co-founders Christian Mochen (CEO), Tom Baron, and Carlo Dela Rosa (COO).

  • Eyebot

    Participated · Series A · Aug 2025

    Eyebot offers a free, 90-second vision test via kiosks that generate prescriptions reviewed and approved by licensed eye doctors under clinical supervision. Tests that indicate unusual findings prompt referrals for in-person comprehensive exams. Its kiosks are deployed in malls, universities, retail stores, pharmacies, grocery chains, schools and airports, and the company also leases kiosks to optical retailers, eyewear brands, and independent practices. Since its seed round, Eyebot has conducted more than 45,000 free vision tests and is on track to deliver over half a million annually; the company says revenue is scaling and the team has doubled. Eyebot was founded in 2021 and is based in Boston. With the new funding, the company plans to scale kiosk deployment and expand its team across product, clinical operations, and commercial growth. Eyebot builds five-foot, self-serve vision-testing kiosks that use computer vision to automatically scan eyes and extract eyeglass or contact lens prescriptions in roughly 90 seconds. Tests are finalized by teledoctors within 24 hours; the technology is registered with the FDA. Consumers pay $30 for an exam, or receive the exam free if they purchase glasses from an Eyebot partner brand; Eyebot plans to earn commissions and rent terminals to eyewear merchants. The kiosks will be placed in shopping centers, grocery stores and pharmacies, and the company plans an initial rollout in New England starting in October. Eyebot cannot perform initial contact-lens fittings but can update existing prescriptions. The company is finalizing partnership agreements with large eyeglass and contact-lens merchants and intends to use new capital to expand to other geographies.

  • Chariot Defense

    Participated · Seed · Jul 2025

    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.

  • Apex

    Participated · Series B · Jun 2024

    Apex manufactures productized satellite buses, the core set of components that enable spacecraft movement, communications, and power. Customers attach payloads such as sensors or radios to Apex's buses to carry out missions. The company launched its first bus in March 2024 and has a growing number of customers and secured orders from prime contractors including the U.S. Department of Defense. Apex plans to use the $95m Series B to increase production to meet customer demand. The round was led by XYZ Venture Capital and co-led by CRV, with participation from a range of new and existing investors. Apex is led by CEO and founder Ian Cinnamon and is based in Los Angeles, California. Apex Space designs and manufactures a standardized 100‑kilogram satellite bus called Aries that supports up to 100 kg of payload mass. The company aims to shorten lead times from years to months by optimizing bus design for manufacturing and configurable customer payloads. Apex is preparing a first demonstration mission on SpaceX’s Transporter‑10 in the first quarter of next year and is already building that Aries unit. The startup plans to open a 50,000‑square‑foot production facility in L.A. called Factory One to support increased manufacturing cadence and intends to produce five more Aries in 2024. Apex has begun selling production slots for upcoming flights, with revenues hitting seven figures. The company was founded by Ian Cinnamon and Max Benassi roughly nine months ago and positions itself as a dual‑use firm serving commercial and defense customers. Apex manufactures spacecraft platforms (satellite buses) for commercial and government customers. Its first product, the Aries satellite bus, is a 103kg platform that can carry customer payloads up to 94kg and supports missions such as earth imaging and communications. The Aries platform is available off the shelf or can be configured to meet specific mission requirements. Apex emerged from stealth after closing an initial $7.5M financing and intends to use the proceeds to ramp up hiring and accelerate production timelines. The company is positioning itself to serve growing demand driven by lower launch costs and an increasing number of commercial and government payloads. The executive team includes CEO Ian Cinnamon, who led Synapse through growth and acquisition by Palantir, and CTO Max Benassi, who scaled aerospace manufacturing at SpaceX and served as Director of Engineering at Astra.
