About SPX
SPX exists to help engineering teams create, run, and validate system behavior before physical hardware is ready.
Why SPX exists
A recurring engineering problem led to SPX: software and integration teams often need to test real behavior before the real system is available.
Hardware arrives late, lab environments stay incomplete, and protocol validation is pushed too far downstream. That delays integration work and turns avoidable issues into expensive, late-stage problems.
SPX is built by HammerHeads Engineers as a product shaped by practical integration, automation, and validation needs rather than by generic simulation storytelling.
What we are building
SPX is an AI-assisted digital twin platform for generating, instantiating, controlling, and validating behavior-rich virtual systems.
The goal is not just to mock interfaces. The goal is to run system-like behavior through one runtime so teams can inspect state, exercise scenarios, and validate protocol flows before deployment.
Run
Instantiate live twins with observable state, runtime controls, and connected protocol behavior.
Validate
Use scenarios, faults, and real communication surfaces to test system behavior earlier.
Who it is for
SPX is designed for teams that cannot afford to wait for complete hardware access before they begin serious integration, debugging, and validation work.
- Integrators working across protocols and device behaviors.
- Automation and control teams validating early system interactions.
- Platform and QA teams building repeatable test environments.
- Engineering teams that need realistic runtime behavior before deployment.
How we work
We treat digital twins as engineering assets, not throwaway demo artifacts. That shapes how SPX is built and how it is meant to be used.
Code-defined models
Models stay reviewable, versioned, and reusable across teams and environments.
Protocol realism
Behavior and communication are tested together instead of being split into disconnected stubs.
Validation before deployment
Scenarios and faults should be exercised before they become field issues.
Developer-first workflows
Docs, examples, MCP workflows, and runtime inspection are part of the product story.
