A Cambridge agri-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.
Founded in 2025 by a trio of Cambridge University scientists, Bindbridge is building a platform that it says defines a category for agriculture: an AI-driven system capable of developing “molecular glues” to specifically break down specific proteins in weeds and pests. The company believes its approach could help address the growing herbicide resistance crisis, 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 enable Bindbridge to expand its eight-person team, further develop its proprietary AI platform and begin laboratory testing of its first agricultural molecular glue candidates within the next 12 months.
The extent of the possibilities is considerable. According to the United Nations, around 40 percent of the world’s crops are lost annually to plant pests, while plant diseases cost the global economy more than $220 billion each year. It is estimated that herbicide-resistant weeds alone destroy $70 billion worth of crops annually. At the same time, regulators are tightening regulations on chemical persistence and environmental impacts, putting pressure on the traditional agrochemical model.
The global agrochemical industry currently spends up to $9 billion per year on research and development, yet it can take up to 12 years for a new active ingredient to come to market. Bindbridge argues that the sector’s traditional discovery methods are slow, expensive and increasingly limited by resistance and regulatory hurdles.
The AI platform BRIDGE is at the center of the company’s strategy. The system uses computer models to design molecular glues, small molecules that trigger the targeted degradation of specific proteins in plants or pests. By leveraging plants’ own intracellular protein control systems, Bindbridge aims to develop more precise, effective and environmentally friendly crop protection products.
Beyond herbicides, the company sees applications for insecticides, fungicides and even sprayable plant traits designed to improve nutrient efficiency, increase heat tolerance or support carbon sequestration.
George Crane, co-founder and managing director of Bindbridge, said the agricultural sector faces “significant performance and sustainability challenges” that require a fundamentally new approach to product development.
“Currently, there is no affordable, rational or systematic way to discover large-scale molecular adhesives for agriculture,” he said. “We use AI to quickly and precisely derive new molecules that can 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 targeted protein degradation projects.
Speedinvest investor Namratha Kothapalli said the company is applying modern AI techniques to one of the world’s most impactful industries. “They open up completely new chemical areas that the industry simply couldn’t reach before,” she said.
The general partner of Nucleus Capital, Dr. Isabella Fandrych, described the platform as a potential breakthrough in combating herbicide resistance and strengthening global food systems. “Their computational approach lays the foundation for a new era of sustainable agriculture,” she said.
The founding team of Bindbridge, Dr. George Crane, Dr. Alex Campbell and Dr. Simeon Spasov, brings experience in machine learning, plant biology, chemistry and venture building. With the new capital, the company aims to position itself as a disruptive force in agricultural research and development, combining sound science with scalable AI to address one of the most pressing challenges in global food security.
