Bindbridge raises $3.8m to fight herbicide resistance with AI-engineered crop protection
A Cambridge ag-biotech startup aiming to reinvent crop protection has secured $3.8 million in early stage funding to accelerate the development of next-generation herbicides and pest control products using artificial intelligence.
Bindbridge, founded in 2025 by three scientists from the University of Cambridge, is building what it describes as a platform that defines the agricultural sector: an AI-driven system that can design “glue molecules” to target and destroy specific proteins in weeds and pests. The company believes its approach could help tackle the growing problem of weed resistance, which is estimated to cost farmers tens of billions of dollars each year.
The funding round was led by Speedinvest and Nucleus Capital, two investors focused on deeptech and climate innovation. The support will allow Bindbridge to expand its eight-person team, develop its proprietary AI platform and begin laboratory testing of the first candidates for an agricultural molecular glue within the next 12 months.
The level of opportunity is great. According to data from the United Nations, about 40 percent of the world’s crops are lost to planting insects each year, and plant diseases cost the world economy more than 220 billion dollars each year. Herbicide-resistant weeds alone are estimated to destroy $70 billion worth of crops annually. At the same time, regulators are tightening regulations on chemical resistance and environmental impact, putting pressure on the traditional agrochemical model.
The global ag-chem industry currently spends up to $9 billion a year on research and development, yet it can take up to 12 years to bring a new effective ingredient to market. Bindbridge says the industry’s traditional acquisition methods are slow, expensive and increasingly subject to regulatory hurdles.
At the core of the company’s strategy is its AI platform, known as BRIDGE. The program uses mathematical models to design molecular glues, small molecules that initiate the targeted degradation of specific proteins within plants or insects. Using plant protein control systems, Bindbridge aims to create more precise, potent and environmentally friendly plant protection agents.
Beyond herbicides, the company sees applications for insecticides, fungicides and plant sprays designed to improve nutrient efficiency, improve heat tolerance or support carbon sequestration.
George Crane, founder and chief executive of Bindbridge, said the agricultural sector was facing “major operational and sustainability challenges” that required a fundamentally new approach to product development.
“Currently there is no affordable, rational or systematic way to obtain molecular glues on a scale in agriculture,” he said. “We’re using AI to quickly and accurately discover new molecules that could change the future of agriculture.”
The investment will also support joint development discussions with major agrochemical companies. Bindbridge says it is already in late-stage discussions with industry players to collaborate on projects aimed at protein degradation.
Speedinvest investor Namratha Kothapalli said the company is using modern AI techniques in one of the most impactful industries in the world. “They’re opening up a whole new area of chemicals that the industry couldn’t access before,” he said.
Nucleus Capital general partner Dr Isabella Fandrych described the platform as a potential breakthrough in fighting herbicide resistance and strengthening food systems around the world. “Their integrated approach lays the foundation for a new era of sustainable agriculture,” he said.
Bindbridge’s founding team, Dr. George Crane, Dr. Alex Campbell and Dr. Simeon Spasov, brought extensive machine learning experience in engineering, plant science, chemistry and business development. With the new capital, the company aims to position itself as a disruptive force in agricultural R&D, combining deep science and cutting-edge AI to address the most pressing challenges in global food security.
