Seattle-based Carbon Robotics, which offers an AI-powered deweeding robot, raises $27M Series B, bringing total funding to $36M
Investors are putting more cash behind the self-driving weed-zapping machines made by Carbon Robotics that are attracting attention from farmers across the world.
Context & Ripple Effects
Carbon Robotics' $27M Series B lands in a weeding-robotics category already drawing venture money: FarmWise had raised a $14.5M Series A in 2019 on a camera-and-cutter approach, and weeks after this round Blue White Robotics closed a $37M Series B for retrofitting existing farm machinery with autonomy.
The bet paid forward: by late 2024 Carbon Robotics had grown this $36M base into a $70M Series D led by BOND and $157M total raised, making this round the early marker of how quickly capital scaled behind laser-based weed control.
First-order effects
- Carbon Robotics gets runway to scale production and global deployments of its self-driving weed-zapping machines, which were already attracting farmer attention worldwide at the time of the raise.
Second-order effects
- Competing approaches now fight over the same farm budgets: FarmWise's identify-and-cut robot and Blue White's retrofit-autonomy model force buyers to weigh machine cost against herbicide savings across rival platforms.
Third-order effects
- If the funding trajectory holds — from this Series B through the later $157M total — mechanical weed control backed by AI perception structurally shifts spend away from agricultural chemicals toward capital-equipment purchases, reshaping who captures value in crop protection.
The trend: Venture capital is scaling autonomous weeding robots into a substitute for chemical herbicides, turning farm weed control into a funded hardware-platform race.
