Simplify's Take

What believers are saying

  • June 2026 Epsilon3 2.0 launches deepen cross-company collaboration and AI automation.
  • January 2026 reported $75 million Series C funds hiring, security, and product expansion.
  • Re-signed ARKA in July 2024 and added over 135 organizations by June 2026.

What critics are saying

  • Microsoft, Atlassian, Tulip, and Dozuki commoditize procedure software before Epsilon3 scales.
  • FedRAMP High audits, monthly reporting, and annual 3PAO reviews raise costs and slow releases.
  • If aerospace primes standardize on generic PLM stacks, Epsilon3 becomes a niche workflow tool.

What makes Epsilon3 unique

  • FedRAMP High certification makes Epsilon3 the strictest-security execution platform in 2025.
  • Epsilon3 2.0 unifies workflows, traceability, inventory, and quality across organizations.
  • NASA, Blue Origin, and Firefly use Epsilon3 across roughly 30% of U.S. orbital launches.

Epsilon3 launches 2.0 platform to connect aerospace, defense, and energy ecosystems across mission-critical operations

Epsilon3 has launched Epsilon3 2.0, a unified operational coordination platform for aerospace, defence, energy and advanced manufacturing sectors. The platform aims to address inefficiencies in complex hardware programmes, which added nearly $50 billion in projected costs across major defence initiatives in 2025 alone. Founded by Laura Crabtree and Max Mednik, Epsilon3 currently supports over 135 organisations, including NASA, Blue Origin and Firefly Aerospace, representing approximately 30% of US orbital launches. The platform is the first FedRAMP High-certified execution platform available. Epsilon3 2.0 introduces three capabilities: Epsilon3 Connect for cross-organisational collaboration, Dashboards for real-time operational visibility, and an MCP Server for AI-driven automation. The platform consolidates workflows, data, inventory management and quality control into a single operational thread across programme lifecycles.

Epsilon3 launches Epsilon3 2.0, expanding operational coordination across the world's most high-stakes industries.

Epsilon3 launches Epsilon3 2.0, expanding operational coordination across the world's most high-stakes industries. PR Newswire New capabilities enable organizations in aerospace, defense, energy, and advanced manufacturing to collaborate through a first-of-its-kind shared, traceable operational record EL SEGUNDO, Calif., June 2, 2026 /PRNewswire/ - Epsilon3 today announced the launch of Epsilon3 2.0, a unified ecosystem vision designed to improve coordination across complex hardware programs. The launch represents a major shift in Epsilon3's broader mission - from connecting teams within organizations to connecting ecosystems across the world's highest-stakes operations. Today, complex hardware execution is still burdened by siloed systems, fragmented records, and manual coordination across organizations. As programs become more complex, the cost of those inefficiencies continues to rise - major defense programs added nearly $50 billion in projected costs in 2025 alone. Epsilon3 2.0 addresses these problems with a first-of-its-kind platform that brings together all workflows, live data, collaboration, inventory, quality management, procurement, and traceability into a single operational thread across the full program lifecycle. The platform is also the first FedRAMP High-certified execution platform on the market, with additional support and deployment options coming soon. Over the coming weeks, Epsilon3 will be releasing three industry-leading capabilities to operationalize this vision: * Epsilon3 Connect: Seamless sharing and real-time collaboration of procedures, runs, and execution for one continuous digital thread across organizations * Dashboards: Self-serve intelligence capability gives teams real-time visibility into operational activity across Epsilon3 without exporting data into scattered BI tools. * Epsilon3 MCP Server: Low-risk AI-intelligence and interoperability between tools to surface insights, automate actions, and more. Founded by Laura Crabtree and Max Mednik, Epsilon3 today supports more than 135 organizations across aerospace, defense, energy, and advanced manufacturing, including programs representing roughly 30% of U.S. orbital launches through NASA, Blue Origin, Firefly Aerospace, and more. "Getting humans back to the Moon, modernizing defense capabilities, and building the next generation of industrial infrastructure all require unprecedented coordination across government agencies, commercial companies, and supply chains," said Laura Crabtree, CEO and Co-Founder of Epsilon3. "Epsilon3 2.0 is our vision for creating the operational foundation that enables these ecosystems to execute as one." "Operational complexity has outpaced the systems most organizations still rely on," said Max Mednik, COO and Co-Founder. "Epsilon3 2.0 creates a unified foundation for collaboration, intelligence, and AI-driven interoperability, moving us closer to true hardware-software convergence."
