Two teenage founders walked into Y Combinator co-founder Paul Graham’s yard with an concept nobody in agriculture appeared to need — an AI mannequin to assist design higher pesticides. By the point they left, that they had a brand new enterprise mannequin, a brand new firm, and finally, Graham’s backing.
Now, that reimagined firm — Bindwell — has raised $6 million in a seed spherical, co-led by Basic Catalyst and A Capital, with a private test from Graham himself. Fairly than promoting AI instruments to legacy agrochemical giants, the startup is utilizing its personal fashions to design new pesticide molecules in-house and license the IP immediately — a shift in technique geared toward modernizing a legacy trade nonetheless dominated by decades-old chemistry.
Pesticide use in agriculture has doubled over the past three many years, but as much as 40% of worldwide crop manufacturing continues to be misplaced to pests and illnesses yearly, per the UN Meals and Agriculture Group. As pests evolve and develop resistance, farmers are pressured to make use of growing quantities of chemical substances simply to keep up the identical yields — a cycle that damages ecosystems and accelerates resistance even additional. Regulatory strain is mounting, however most agrochemical firms nonetheless depend on tweaking legacy compounds. Bindwell is betting that AI can break the cycle by discovering completely new, extra focused molecules — ones designed from scratch for contemporary challenges.
Based in 2024 by Tyler Rose, 18, and Navvye Anand, 19, Bindwell adapts AI-led drug discovery strategies to agriculture, with the objective of rushing up how new pesticide molecules are recognized and examined.
Bindwell started as a analysis mission in late 2023, when Rose and Anand have been college students on the Wolfram Summer time Analysis Program. They initially targeted on a drug discovery AI mannequin referred to as PLAPT, which concerned binding affinity prediction — work that was later cited in a Nature Scientific Reviews paper on most cancers therapeutics. In 2024, they started exploring how the identical strategy might be utilized to pesticides.
Each founders had private publicity to the issue. Rose realized in regards to the challenges of pest management from his aunt, who farms in China. Anand, who has roots in Punjab, noticed firsthand how restricted pesticide choices affected crop yields.
“Agriculture has been in our thoughts area,” stated Rose in an interview. “That led to the conclusion that we will use the very same know-how that has been profitable in drug discovery. We are able to deliver that over to pesticide discovery, as a result of the biochemistry is similar, however pesticides are such an enormous downside, and I really feel prefer it’s not very targeted on by most individuals.”

Rose and Anand entered Y Combinator’s Winter 2025 batch with plans to construct AI fashions and promote their entry to main agrochemical firms. However they didn’t discover traction — most trade gamers have been reluctant to undertake AI as a core a part of pesticide discovery. Halfway by way of this system, they have been invited to Paul Graham’s residence, the place they spoke with him for about 45 minutes on the again patio.
After listening to about their challenges, Graham instructed a special strategy: Fairly than promoting instruments, they may use their very own fashions to find new pesticide molecules themselves. That dialog marked the start of Bindwell’s present path.
“The founders [of Bindwell] will in all probability do alright,” he later posted on X. “They’re sensible and have a good suggestion.”
Bindwell has developed its personal AI suite designed to scale back hallucination — a standard subject the place fashions produce unreliable or unsupported outputs. The software program consists of Foldwell, a construction prediction mannequin, which is a customized diffusion system impressed by DeepMind’s AlphaFold, used to determine goal protein constructions. It additionally consists of PLAPT, an open supply protein-ligand interplay mannequin able to scanning each recognized synthesized compound in below six hours, and APPT, a protein-protein interplay mannequin for biopesticide screening, reported to outperform current instruments by 1.7× on the Affinity Benchmark v5.5. Furthermore, the suite incorporates an uncertainty quantification system that flags when outcomes are reliable and when extra information is required.
“Since we’re not promoting AI fashions, we’re not competing with firms that promote fashions,” Rose informed Trendster.
Collectively, Bindwell’s fashions can analyze “billions” of molecules, the startup stated, and ship 4 occasions quicker efficiency than DeepMind’s AlphaFold 3.
“The way in which most pesticides are found proper now is just not target-based,” stated Rose. “Entomologists and chemists recommend completely different compounds, then take a look at them on bugs. You typically must synthesize and take a look at hundreds of chemical substances, which is pricey simply to test for efficacy. With our AI fashions, you’re in a position to simplify the issue right down to a single protein.”
The AI helps determine proteins which can be distinctive to a selected pest however absent in people, helpful bugs, or aquatic organisms like water fleas.
“As soon as you discover these proteins, you may design one thing that binds to them and stops them from working,” Rose stated.
Bindwell is at present testing the efficacy of its AI-generated molecules at its lab in San Carlos. It is usually working with a third-party companion to additional validate the fashions, although Rose declined to share particulars.
Rose stated the startup is in early discussions with a number of world agrochemical corporations, with its first partnership deal anticipated to shut quickly. “A 12 months from now, we wish to be coming into into our licensing offers with a few of these firms,” he stated. Bindwell has additionally begun talks with stakeholders in India and China to conduct discipline assessments.
The startup at present has a crew of 4, and in addition works with exterior contractors for molecule synthesis.
Bindwell’s seed spherical additionally included participation from SV Angel, alongside Graham. Previous to becoming a member of Y Combinator’s Winter 2025 batch, the startup raised a pre-seed spherical from Character Capital.
