These independent companies offer consulting services on A2UI.
Developer tools 
Streams A2UI Express and JSON surfaces from Gemini Flash over AG-UI while a side-by-side inspector displays the compiled wire operations. Switches live between CopilotKit Standard, shadcn/ui, Material 3 Expressive, and custom catalogs without re-running the agent.
E-commerce 
Pairs conversational outfit search with a synchronized dressing room across dual-pane mobile and web layouts. Host code validates catalog and basket state locally, and an in-app inspector displays raw A2UI message batches.
Finance 
Models borrowing limits and rent-versus-buy horizons for Stockholm and Lisbon housing markets. Deterministic Dart tools calculate tax and amortization schedules locally and attach source provenance to each figure.
Healthcare 
Streams clinical check-in surfaces from Python ADK agents over the A2A transport. Pairs 18 standard A2UI primitives with 10 custom widgets (including BodyMapPicker and BloodPressureInput) while keeping vital-sign classification in typed Dart models.
Healthcare 
Compiles longitudinal patient records and check-in notes into visit-specific physician briefs before an appointment starts. Runs A2UI Express on Dart Cloud Functions to compose 14 medical widgets including SafetyBanner, TrendChart, ImagingTimeline, and EcgStrip.
Finance 
Implements the A2UI wire protocol across six multi-state portfolio surfaces: attribution waterfalls with drill-down recomposition, short/long-term tax-lot tables, scenario comparisons, editable draft order tickets, payoff charts, and holdings breakdowns.
AI Engineering 
Runs base and fine-tuned Gemma 4 models in the browser over WebGPU and the Chrome Prompt API with zero server inference. Compiles streamed A2UI Express into Angular surfaces and feeds compiler diagnostics back into local retry loops.
Smart home 
Renders shared household surfaces on a wall-mounted kitchen display using a validated 12x2 grid. Pairs Gemini Live voice input with real-time WebSocket updateDataModel appliance telemetry, time-of-day themes, and multi-persona schedules.
