We don’t just advise — we build the tools that make the advice stick. Every engagement can be paired with the PROmeter product family so the work survives after we leave.
Metrix — in Measurement & governance
KPI programmes land on a real board you can open on Monday — not a slide deck of what you’ll measure one day.
See Metrix →Calix & Semantix — in AI workflow
Review automation and change-impact intelligence integrated into your tools, backed by our Anthropic Claude partnership.
See the PROmeter family →Helix — in MBSE & Process
BPMN process definitions with formal, metric-driven gates — the processes you architect become processes the tool enforces.
See Helix →Regulated and critical, cross-industry
Experience spanning the most demanding engineering environments.
Our product family: PROmeter
PROmeter Metrix turns the KPI story above into a tool: author KPIs in a readable DSL, run them against your engineering data, and show results on boards reviewers actually read. Calix, Semantix and Helix extend the platform into AI-assisted review, change-impact analysis and governance.
