## Summary

Epsilon3 provides launch operations and test management software for aerospace teams, replacing paper procedures with digital runbooks used by SpaceX, NASA contractors, and leading space startups.

## Company Overview

Epsilon3 is an aerospace operations software company that modernizes how space and aerospace teams manage complex procedures, test plans, and launch operations. Founded in 2021 by Laura Crabtree, Max Mednik, and Ryan Pallister—veterans of SpaceX and Google—the company builds digital runbook and procedure management software that replaces the binders and spreadsheets aerospace teams have relied on for decades.

The Epsilon3 platform allows engineers to create, execute, and track complex multi-step procedures in real time, with built-in collaboration, sign-off workflows, and automated data capture. During a rocket launch or spacecraft test campaign, dozens of engineers must execute thousands of time-critical steps in precise sequence—Epsilon3's software coordinates these activities, reduces human error, and provides a complete audit trail of every action taken. The company raised a Series A led by Andreessen Horowitz and has become a standard tool across commercial launch providers, satellite operators, and space systems integrators.

Beyond launch operations, Epsilon3 has expanded into broader aerospace test and manufacturing workflows, helping teams manage acceptance testing, qualification campaigns, and production verification. The platform's structured data capture also enables analytics over historical procedures, helping organizations identify patterns in anomalies and optimize their operational practices over time.
