Greenfield Robotics envisions a world where farms and the food you eat are chemical-free.

But chemicals are often used to remove invasive weeds. So, what’s the answer? This company believes it’s robots.

Greenfield has created autonomous, chemical-free weed-control robots that deliver precise performance. These bots are simple to operate, cost-effective, and manufactured in the U.S. And they’ve been running on paying fields for the past four years.

Founded by a third-generation farmer and tech entrepreneur, Greenfield combines expertise in Artificial Intelligence (AI), engineering, and regenerative agriculture to eliminate all chemicals.

Reservations for the company’s robots are already filled for 2026. And notable investors/customers include fast-casual restaurant Chipotle, Innovative Livestock Services (one of the country’s largest beef producers), and Mid Kansas Cooperative (an agricultural co-op that represents 11,000 farmers).
