Profile

Four Growers, Inc. is an agricultural robotics company headquartered in Pittsburgh, Pennsylvania. The company develops autonomous harvesting systems and crop-analytics technologies for commercial greenhouse growers, with an initial emphasis on tomatoes and additional applications for peppers and cucumbers.

Four Growers was established in 2018 by Brandon Contino and Dan Chi after beginning as a student-led venture at the University of Pittsburgh. The privately held company operates at the intersection of robotics hardware, computer vision, artificial intelligence, motion planning, and agricultural data analysis. Its systems are designed for high-density commercial greenhouse environments, where robots must identify produce among leaves and vines, determine ripeness, handle crops without damage, and operate under changing biological and environmental conditions.

The company’s primary robot platform is the GR-100, an autonomous tomato-harvesting system developed for commercial greenhouse operations. The robot uses a robotic arm and multiple stereo cameras to detect ripe tomatoes, plan harvesting movements, pick fruit, perform quality checks, and place harvested produce into storage. Four Growers states that the platform can operate continuously and can be monitored remotely through a centralized dashboard.

In addition to automating harvesting, Four Growers collects visual and operational data while its robots move through greenhouse rows. This information supports plant analytics, fruit counting, yield measurement, and heatmaps that help growers understand production differences within specific greenhouse areas. Combining physical automation with crop intelligence distinguishes the company from agricultural robotics suppliers that concentrate only on mechanizing a single manual task. Four Growers positions its harvesting robots as part of a broader greenhouse-management platform rather than as standalone picking machines.

Commercial greenhouse harvesting presents several technical challenges. Produce does not grow in uniform positions, vines and leaves can block cameras or robotic arms, and fruit must be evaluated and handled without reducing its market value. Four Growers addresses these problems through integrated perception, robotic manipulation, crop-specific software, and repeated deployment in operating greenhouses. Its systems are designed to perform within existing greenhouse production environments rather than requiring farms to replace their underlying growing infrastructure.

The company works with greenhouse operators in multiple international markets and has deployed robotic systems in commercial facilities in North America, Europe, and other major growing regions. The Netherlands serves as its European base for sales, customer support, and fleet deployment. Four Growers reports that its technology is used to harvest large volumes of tomatoes while gathering data that can support operational and yield-management decisions.

Within the robotics industry, Four Growers contributes to the expanding field of agricultural automation by applying autonomous perception and manipulation to a repetitive, labor-intensive crop-harvesting process. Its work reflects a broader movement toward purpose-built robots that combine physical work with continuous environmental data collection. The company’s systems are intended to help greenhouse growers manage labor shortages, maintain harvesting consistency, reduce uncollected produce, and increase the amount of acreage that existing agricultural teams can support.
