Epsilon3 is building web-based procedure and operations management software designed for high-stakes hardware environments across aerospace, defense, and advanced manufacturing. Founded in 2020 by former SpaceX and Epirus leaders, the 30-person Series A startup has raised $23.5 million from investors including Lux Capital, Y Combinator, General Catalyst, Lightspeed Venture Partners, and Space Capital. According to PR Newswire, Epsilon3 expanded its product suite with the launch of Epsilon3 2.0, introducing cross-organizational procedure sharing through Epsilon3 Connect, self-serve operational intelligence dashboards, and AI-driven interoperability via an MCP server. The platform serves over 135 organizations and powers operations behind roughly 30% of U.S. orbital launches, supporting customers such as NASA, Blue Origin, Firefly Aerospace, and Commonwealth Fusion Systems.
The company was co-founded by Chief Executive Officer Laura Crabtree, Chief Operating Officer Max Mednik, and founder Aaron Sullivan. Laura Crabtree spent over a decade at SpaceX as a mission operations engineer and Crew Operations & Resource Engineer (CORE) lead trainer for the Demo-2 astronaut mission, following an earlier engineering role at Northrop Grumman. Max Mednik, a Stanford University and UCLA Anderson graduate, previously co-founded technology firm Epirus. Aaron Sullivan, who studied computer science at Stanford University, served as chief engineer during Epsilon3's early development. Speaking in an interview on the New York Stock Exchange, Crabtree noted that Epsilon3 was built to give fast-moving hardware teams modern software infrastructure to execute complex procedures safely without relying on spreadsheets or paper checklists.
Expanding Platform Capabilities Across High-Stakes Sectors
Epsilon3's core platform unifies procedure authoring, real-time execution, inventory tracking, calibration coordination, and non-conformance reporting into a single operational thread. As showcased in a product walkthrough by Epsilon3, the software provides role-based sign-offs, step-by-step instructions, automated error checking, and live telemetry feeds to maintain an audit trail for critical hardware tests. The platform achieved FedRAMP High certification, making it one of fewer than 70 SaaS products authorized to meet the federal government's highest security standards.
In addition to satellite and space mission operations, Epsilon3 has expanded into nuclear energy, defense programs, and advanced manufacturing. Reporting from Payload Space detailed how the team added features for tracking assembly processes, schedule timelines, and large data analysis based on direct operator feedback. In an interview published by TechCrunch, Mednik explained that complex business workflows across energy, fusion, and defense require strict compliance and verification tools similar to rocket launch operations.
