Agents have reached hardware. Meet Flow v3 

Build from a shared, living model.
Of the entire program.

Engineering data lives in a dozen disconnected tools. Flow builds a live, continuously updated model of your entire program and keeps every relationship current automatically.

Flow creates a live Systems Graph, a connected, continuously updating model of the entire engineering program. Every artifact, requirements, interfaces, architectures, design units, test cases, simulations, software components, compliance evidence, exists as a node with explicit relationships to everything it impacts.

01

One source of truth.

Every engineer and agent works from the same live baseline. Alignment is structural, not managed.

02

Conflicts caught early.

Rework and schedule risk stay contained instead of cascading across the program.

03

Impact analysis in seconds.

Change a requirement & the graph shows what's affected, what breaks, and what needs retesting.

Millions of connections.
One living model.

Every consequence of a change.
Flagged in seconds.

Agents reconcile changes across GitHub, CAD, and PLM, surfacing conflicts the moment they appear rather than at integration.

One spec changes.
The agents handle the rest.

Supplier updates cooling spec.

One PDF lands in SharePoint and is pulled into Flow automatically.

Supplier Cooling Spec

The graph flags downstream impacts.

The requirement written against the old spec goes Suspect, and so do the test cases verifying it.

And so much more.

Cross-project requirement linking.

Link requirements across project and team boundaries. When a system-level requirement changes, downstream requirements in supplier projects are flagged automatically.

Live parameter references.

Reference a parameter inside a requirement and downstream tools read its current value through the API. The number stays right as the design moves.

Views scoped to anyone.

Filter by domain, stakeholder, supplier, or regulatory source. Filters scope automatically to whoever is viewing, so building one works for the whole team.

Findings where engineers work.

Agents post directly into GitHub PRs, Slack threads, and CAD. The program stays coherent in the tools the team already uses.

We're building a complex autonomous system, and things change fast. We didn't want a tool that slows us down. Flow was built for the kind of iterative engineering we actually do.
