Epsilon3 offers a web-based platform for managing complex operational procedures across projects that enable satellite deployment and operations, human spaceflight, launch operations, vehicle manufacturing, integration & test, robotics deployment, testing, and more. The platform is used by aerospace, defense, manufacturing, and enterprise customers. Since its founding in 2021, Epsilon3 has powered thousands of procedures and multiple types of operations. The company is led by CEO Laura Crabtree and is based in Los Angeles, CA. The article does not provide revenue or user counts. The article also does not describe specific future plans or use of proceeds. Epsilon3 offers an "OS" for launch and launch-related operations that replaces spreadsheets and Word docs with a collaborative work platform. Its product includes an API for live telemetry, multiple-operator sign-off, audit trails, and integrations to pull data from other tools. Customers use the platform for launch ops, satellite operations, hardware integration and testing, and other workflow-heavy processes where auditability and repeatability matter. The company reports a roughly 50x increase in ARR since last year and has more than tripled its customer count to a couple dozen paying customers, including Firefly, Astrobotic, OrbitFab, Venus, Gilmour Space and Stoke Space. The team has grown from the three founders to 21 employees and the founders include CEO Laura Crabtree and cofounder/engineer Aaron Sullivan; the company went through Y Combinator's Summer 2021 cohort. With the new funding the company plans to continue expanding the product and hiring to support larger customers and additional integrations. Epsilon3 has developed an operating system for launch operations—an electronic toolkit for controlling and editing workflows and procedures described in the article as “Asana project management meets GitHub version control.” The product targets integration of design, manufacturing, integration tests and operations to reduce errors and improve efficiency in high-stakes launch environments. The company is laser-focused on space customers, supporting live launches for early-stage rocket companies such as Stoke Space. Co-founders include Laura Crabtree, a former senior missions operations engineer at SpaceX, serial entrepreneur Max Mednik, and Aaron Sullivan, a former Google engineer. Epsilon3 positions itself amid a growing market as access to space expands, with the launch services industry cited as possibly exceeding $18 billion by 2026. Financial and operating metrics (revenue/users) are not disclosed in the article.
