Next-gen hardware teams use Flow to connect requirements, design, CAD, and testing in a shared system, surface conflicts early, and accelerate cycle times.
Trusted by tens of thousands of engineers across the fastest-moving engineering teams
Requirements, design, CAD, and testing connected in one live system.
Flow creates a live chain all the way down to verification evidence.
Agents continuously review every change and surface conflicts as soon as they arise.
Model your team’s system hierarchy your way. By level, subsystem, or domain. Requirements, architecture, parameters, and verification live in the same tree, so every engineer works from the same picture.
Agents trace dependencies, check coverage, and verify every change against your standards. On every iteration, automatically. Your team is left with the calls only humans can make.

Engineers keep working in CAD, GitHub, SharePoint, and Slack. Flow syncs in the background. Agents run on every push and pull. No migration. No downtime. No rip and replace.

System Architect
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.
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.

Every requirement, interface, test, and design, linked. When one changes, the graph knows what depends on it. Agents reason across the whole program.
A two-person robotics team and a sixteen-brand automotive group don't run programs the same way. The graph adapts to your program, not a template.
Agents test changes on a branch. The live program stays stable. Nothing is real until an engineer reviews and merges.
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.
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, ISO 27001, GDPR, and CCPA.
Private inference, full audit trail on every AI action, and nothing ever used for model training.
Guide
Every generation of hardware has broken the methodology that worked for the last one. This handbook defines what comes next: continuous alignment powered by AI agents, the infrastructure it depends on, and the role shift it demands from every systems engineer.
