At FarmWise we believe that farming can be done at the plant level at scale leveraging the diversity of biological systems. Our team wants to enable farmers and ag equipment makers to reinvent farming operations with machines that can perceive, understand and act at the plant level in real-time. For years, FarmWise operated a commercial fleet of automated weeder prototypes across the greater Salinas Valley in California. After over 20,000 acres of commercial weeding and associated learnings, FarmWise released its Vulcan precision implement in 2023. Vulcan is a unique intra-row weeder and precision cultivator designed for durability and efficient weeding. Vulcan is powered by FarmWise's Intelligent Plant System (IPS), the most advanced computer vision architecture made for agricultural applications.
