Join the invite-only beta
ChangeSpan is an offline-first desktop app for closed-loop project controls: schedule logic → results → controls/cost forecast → impacts/scenarios → explainability. We’re starting with federal heavy civil and expanding to DOT and vertical.
What you’ll get in beta
- Windows beta invite link (as capacity allows)
- Sample project files (CSV) for evaluation
- Guides for the closed-loop workflow
Beta is invite-only so we can keep feedback tight and support manageable.
Trust & model
- Offline-first (no mandatory cloud)
- File-based project folders
- Audit trail + snapshots
- Lock/read-only safety
