A workflow OS for virtual and hybrid production targeting indie film/TV studios and commercial shops adopting LED volumes and Unreal-based workflows who currently juggle Shotgrid, spreadsheets, and ad-hoc versions. These teams complain in pro forums that coordination between physical set, virtual art, and post is fragile, causing overruns and asset chaos. StageFlow connects to DCC tools (Unreal, Blender), camera metadata, and volume controllers to create a single source of truth for scenes, assets, and takes, visible to producers, VFX, and on-set crew. It tracks what was shot on which wall configuration, flags continuity risks, and provides cost/time dashboards tied to virtual scene adjustments. Pricing is per-production SaaS with onboarding, expanding to seat licenses for recurring studios; moat comes from deep pipeline integrations and template libraries tuned to virtual production best practices.
