Prototype
Shape working software
AI-assisted prototyping turns domain context into usable software that can be reviewed, tested, and promoted.
Yttrigen · Validated Velocity
ValidKeep is open-source software focused on requirements, traceability, change control, and software validation. Yttrigen maintains its source, documentation, trademarks, and intellectual property. We currently offer no paid subscriptions, hosted services, consulting, or other commercial services.

Assurance pipeline
One governed path from prototype to production, with evidence attached at every stage.
Govern
Promote into control
A Yttrigen Project gives the work a governed lifecycle with change context, traceability, and review points.
Validate
Prove the behavior
ValidKeep connects requirements, OQ drivers, PQ telemetry, signatures, and release evidence.
Deploy
Release with handoff
Yttrigen delivery prepares the validation package, environment path, deployment record, and operating handoff.
Operate
Preserve continuity
The production path keeps evidence, operational context, and support decisions attached to the software.
Traceability
Every important decision has a line back to intent.
OQ Evidence
Business behavior is exercised, not merely described.
PQ Evidence
The running system proves its operating profile.
Release Gates
Promotion is explicit, reviewable, and recorded.
Studio walkthrough context
The homepage video preserves a walkthrough of the Studio-to-validation concept for informational and historical context. Studio access is not currently offered.
