What Epsilon3 does

Epsilon3, Inc. is a Santa Monica-based private SaaS company founded in 2021 by Laura Crabtree (CEO) and Max Mednik (COO) that builds an AI-powered procedure and resource management platform for high-stakes engineering, manufacturing, testing, and operational workflows. The platform unifies functions historically split across MES, ERP, PLM, QMS, and CMMS stacks — including scheduling, manufacturing execution, electronic procedures, test management, time-series analysis, shift logs, issues/NCR/CAPA, risk, document management, and an AI assistant — into a single execution layer with native integrations for YAMCS, Cosmos, Teamcenter, Valispace, Jira, Slack, Jama, QuickBooks, and Odoo via a public REST API.

The core execution engine supports conditional logic, revision control, step-level telemetry binding, and role-based sign-offs, and is hosted on AWS with four separate production environments (US, UK, EU, and FedRAMP High on AWS GovCloud). The June 2026 launch of Epsilon3 2.0 is positioned as the first FedRAMP High-certified execution platform on the market, serving 135+ organizations including NASA, Blue Origin, Firefly Aerospace, Redwire, Rocket Lab, Virgin Galactic, General Atomics, Sierra Space, Axiom Space, AeroVironment, ARKA Space & Defense, Impulse Space, Commonwealth Fusion Systems, and Shift4 — collectively representing roughly 30% of U.S. orbital launches.

Epsilon3 makes money primarily through recurring SaaS subscriptions (monthly or annual billing) with quote-based pricing, supplemented by free-trial acquisition, professional services for custom integrations, and an emerging federal procurement channel via the AWS Marketplace for the U.S. Intelligence Community (ICMP). Go-to-market is hybrid: enterprise field sales targeting aerospace, defense, and federal buyers (gated by FedRAMP High and ITAR certifications) combined with a self-serve "Start Trial" funnel for startups and mid-market. Cumulative disclosed funding is approximately $17.8M across pre-seed, seed, Series A, and earlier rounds through 2022 (including a $15M Series A led by Lux Capital in June 2022), with investors including Lux Capital, Moore Strategic Ventures, Y Combinator, MaC Venture Capital, Broom Ventures, Pioneer Fund, Soma Capital, Stage Venture Partners, Village Global, Pareto Holdings, and Kohala Ventures.

Core offering

Epsilon3 sells an AI-powered procedure execution and process/resource management SaaS platform that digitizes and orchestrates complex operational workflows for aerospace, defense, manufacturing, and government organizations. It replaces paper/Excel checklists and fragmented MES/ERP/PLM/QMS stacks with a unified execution layer covering scheduling, manufacturing, procedures, test management, data analytics, risk, and documentation. The platform is delivered via cloud, on-premise, hybrid, and classified deployments, including the first FedRAMP High-certified execution environment.

Product overview

Epsilon3 is an AI-powered procedure execution and process/resource management platform designed for advanced engineering, manufacturing, testing, and operations in high-stakes industries. It is delivered as a unified platform-plus-modules architecture with a core execution engine (Execute module) surrounded by specialized modules: Plan (scheduling), Build (manufacturing execution), Test (cases and requirements), Analyze (data/reporting), Discover (insights/trends), Shift (operations logs), Issues & Non-Conformance, Risk Management, Document Management, AI, and API & Integrations. The latest major release, Epsilon3 2.0, unifies these modules into a single operational thread and was launched as the first FedRAMP High-certified execution platform, expanding coverage across aerospace, defense, energy, and advanced manufacturing. Epsilon3 Connect extends the platform's cross-boundary ecosystem.
