Memo
Requirements management and AI agents that continuously align CAD, simulation, code, and test. A living system of record for hardware development.
Trusted by tens of thousands of engineers across the fastest-moving engineering teams


Requirements, design, CAD, and testing connected as one system.
Propose a change and Flow instantly runs impact analysis across every dependency.
Change a requirement, issue, CAD model, or test artifact and Flow propagates the update.
Testimonials

Flow is the requirements management tool of our dreams. It reflects how we work—fast, iterative, and focused on giving everyone a common, integrated view of our system.

Ryan McCullough
System Architect

Flow enables over 1,000 engineers to work efficiently, stay aligned, and maintain rigor, becoming integral to our teams' daily rhythm and making a significant impact.

Rivian designs the R1, R2, R3, and future programs in Flow, uniting 1,500 engineers across battery, drivetrain, controls, and body structures in a single live system of record.
Agents run impact analysis, check test coverage, and verify requirements against your standards on every change. Your engineers make the architectural calls.

Every change, every effect, before it ships.
When an engineer changes a CAD model, commits code in GitHub, or revises a SharePoint document, agents follow it across the program, updating connected artifacts automatically. Every engineering action becomes an automation trigger.

Every requirement, interface, test, and design, linked. When one changes, the graph knows what depends on it. Agents reason across the whole program.

Model your engineering data, relationships, and workflows without being constrained by a predefined schema.

Every proposed change lives on a branch. Compare diffs, review impacts, and merge into the baseline when ready.
Deploy in cloud, GovCloud, or self-hosted, with ITAR, export control, and data residency built in.
ITAR and EAR alignment, NIST 800-171, CUI, SOC 2 Type II, GDPR, and CCPA.
Private inference, full audit trail on every AI action, and nothing ever used for model training.
