ABOUT SENTINEL

Sentinel is a vine-level vineyard management platform built on RTK GPS technology. Operating like digital flagging tape, Sentinel creates a permanent, sub-centimeter-accurate record for every vine on the property. Vineyard crews carry a handheld GPS unit and tag each vine with health status, disease flags, replant decisions, and custom attributes as they walk the rows.

The result is a living digital map of the vineyard where every plant has its own history. Managers can query by any attribute -- block, age cohort, production status, disease flag -- and generate work orders, compliance reports, or data exports directly from the results. The system replaces clipboard-based scouting with GPS-verified records that persist across seasons, crew changes, and ownership transitions.

Founded by vineyard technology practitioners, Sentinel serves premium estate vineyards and vineyard management companies in California, Oregon, and internationally.
