A Cambridge ag-biotech start-up 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 a trio of Cambridge University scientists, is building what it describes as a category-defining platform for agriculture: an AI-driven system capable of designing “molecular glues” to target and degrade specific proteins in weeds and pests. The company believes its approach could help tackle the mounting crisis of herbicide 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 backing will allow Bindbridge to expand its eight-person team, advance its proprietary AI platform and begin laboratory testing of its first agricultural molecular glue candidates within the next 12 months.

The scale of the opportunity is considerable. According to United Nations data, around 40 per cent of global crops are lost to plant pests annually, while plant diseases cost the global economy more than $220 billion each year. Herbicide-resistant weeds alone are estimated to destroy crops worth $70 billion annually. At the same time, regulators are tightening rules on chemical persistence 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 as long as 12 years to bring a new active ingredient to market. Bindbridge argues that the sector’s conventional discovery methods are slow, expensive and increasingly constrained by resistance and regulatory hurdles.

At the core of the company’s strategy is its AI platform, known as BRIDGE. The system uses computational models to design molecular glues, small molecules that trigger the targeted degradation of specific proteins inside plants or pests. By leveraging the plant’s own intracellular protein control systems, Bindbridge aims to create more precise, potent and environmentally responsible crop protection agents.

Beyond herbicides, the company sees applications for insecticides, fungicides and even sprayable plant traits designed to improve nutrient efficiency, enhance heat tolerance or support carbon sequestration.

George Crane, co-founder and chief executive of Bindbridge, said the agricultural sector is facing “significant performance and sustainability challenges” that demand a fundamentally new approach to product development.

“There’s currently no affordable, rational or systematic way to discover molecular glues at scale for agriculture,” he said. “We’re using AI to rapidly and accurately derive new molecules that can change farming’s future.”

The investment will also support co-development discussions with major agrochemical companies. Bindbridge says it is already in late-stage talks with industry players to collaborate on targeted protein degradation projects.

Speedinvest investor Namratha Kothapalli said the company was applying modern AI techniques to one of the world’s most consequential industries. “They’re unlocking entirely new chemical space that the industry simply couldn’t reach before,” she said.

Nucleus Capital general partner Dr Isabella Fandrych described the platform as a potential breakthrough in tackling herbicide resistance and strengthening global food systems. “Their computational approach lays the groundwork for a new era of sustainable agriculture,” she said.

Bindbridge’s founding team, Dr George Crane, Dr Alex Campbell and Dr Simeon Spasov, bring experience spanning machine learning engineering, plant biology, chemistry and venture building. With the new capital, the company aims to position itself as a disruptive force in agricultural R&D, combining deep science with scalable AI to address one of the most pressing challenges in global food security.
