Epsilon3

Founded 2021

Manage assembly procedures and test operations for complex hardware programs

Pricing model

Paid

You can use Epsilon3 to run digital procedures and track testing across complex hardware programs. The system replaces paper checklists and scattered spreadsheets with unified operational records for aerospace, defense, and manufacturing teams. You can author step-by-step assembly guides, capture real-time test telemetry, and log non-conformance issues during production runs. Team members can query past procedures using conversational assistants, review audit trails, and approve design changes with human-in-the-loop verification. It supports strict compliance requirements like ITAR and FedRAMP High across cloud, hybrid, or air-gapped environments.
