Four Growers, Inc. · United States

Pittsburgh-built autonomous greenhouse tomato harvester running the first operational robot fleets in Dutch greenhouses — snack, plum and cherry tomatoes picked by suction with stereo vision at up to 43 kg/h and 98% ripe-detection precision. Fits existing commercial greenhouses with minimal modification; used by grower Westburg and at Syngenta's TomatoVision research facility.

Best for: Large glasshouse tomato operations in the Netherlands or US wanting fleet harvesting of snack/cherry tomatoes plus per-row yield heatmaps and forecasting.
Octinion · Belgium

Strawberry-picking robot for tabletop systems; little public evidence of commercial rollout since ~2021, with Octinion's picking activities continuing under picking.technology — commercial status uncertain.

Best for: Tabletop strawberry growers facing harvest-labour shortages and tight picking windows.
