Synthetic intelligence is shifting shortly into drug discovery as pharmaceutical and biotech firms search for methods to chop years off R&D timelines and improve the probabilities of success amid rising value. Extra than 200 startups are actually competing to weave AI straight into analysis workflows, attracting rising curiosity from traders. Converge Bio is the newest firm to experience that shift, securing new capital as competitors within the AI-driven drug discovery area heats up.
The Boston- and Tel Aviv–based mostly startup, which helps pharma and biotech firms develop medication sooner utilizing generative AI educated on molecular knowledge, has raised a $25 million oversubscribed Collection A spherical, led by Bessemer Enterprise Companions. TLV Companions, Saras Capital and Classic Funding Companions additionally joined the spherical, together with further backing from unidentified executives at Meta, OpenAI, and Wiz.
In apply, Converge trains generative fashions on DNA, RNA, and protein sequences then plugs them into pharma and biotech’s workflows to hurry up drug growth.
“The drug-development lifecycle has outlined levels — from goal identification and discovery to manufacturing, medical trials, and past — and inside every, there are experiments we will help,” Converge Bio CEO and co-founder Dov Gertz mentioned in an unique interview with TechCrunch. “Our platform continues to increase throughout these levels, serving to convey new medication to market sooner.”
To date, Converge has rolled out customer-facing techniques. The startup has already launched three discrete AI techniques: one for antibody design, one for protein yield optimization, and one for biomarker and goal discovery.
“Take our antibody design system for instance. It’s not only a single mannequin. It’s made up of three built-in elements. First, a generative mannequin creates novel antibodies. Subsequent, predictive fashions filter these antibodies based mostly on their molecular properties. Lastly, a docking system, which makes use of physics-based mannequin, simulates the three-dimensional interactions between the antibody and its goal,” Gertz continued. The worth lies within the system as an entire, not any single mannequin, in accordance with the CEO. “Our clients don’t should piece fashions collectively themselves. They get ready-to-use techniques that plug straight into their workflows.”
The brand new funding comes a few 12 months and a half after the corporate raised a $5.5 million seed spherical in 2024.

Since then, the two-year-old startup has scaled shortly. Converge has accomplished over 40 applications with greater than a dozen pharmaceutical and biotech clients, Gertz mentioned. It really works with clients throughout the U.S., Canada, Europe and Israel and is now increasing into Asia.
The staff has additionally grown quickly, rising to 34 staff from simply 9 in November 2024. Alongside the way in which, Converge has begun publishing public case research. In a single, the startup helped a associate increase protein yield by 4 to 4.5X in a single computational iteration. In one other, the platform generated antibodies with extraordinarily excessive binding affinity, reaching the single-nanomolar vary, Gertz famous.
AI-driven drug discovery is experiencing a surge of curiosity. Final 12 months, Eli Lilly teamed up with Nvidia to construct what the businesses referred to as the pharma trade’s strongest supercomputer for drug discovery. And in October 2024, the builders behind Google DeepMind’s AlphaFold undertaking gained a Nobel Prize in Chemistry for creating AlphaFold, the AI system that may predict protein constructions.
When requested in regards to the momentum and the way it’s shaping Converge Bio’s progress, Gertz mentioned that the corporate is witnessing the most important monetary alternative within the historical past of life sciences and the trade is shifting from “trial-and-error” approaches to data-driven molecular design.
“We really feel the momentum deeply, particularly in our inboxes. A 12 months and a half in the past, once we based the corporate, there was a number of skepticism,” Gertz instructed TechCrunch. That skepticism has vanished remarkably shortly, because of profitable case research from firms like Converge and from academia, he added.
Giant language fashions are gaining consideration in drug discovery for his or her capability to investigate organic sequences and counsel new molecules, however challenges like hallucinations and accuracy stay. “In textual content, hallucinations are normally straightforward to identify,” the CEO mentioned. “In molecules, validating a novel compound can take weeks, so the price is far greater.” To deal with this, Converge pairs generative fashions with predictive ones, filtering new molecules to scale back danger and enhance outcomes for its companions. “This filtration isn’t excellent, but it surely considerably reduces danger and delivers higher outcomes for our clients,” Gertz added.
TechCrunch additionally requested about consultants like Yann LeCun, who stay skeptical about utilizing LLMs. “I’m an enormous fan of Yann LeCun, and I utterly agree with him. We don’t depend on text-based fashions for core scientific understanding. To really perceive biology, fashions should be educated on DNA, RNA, proteins, and small molecules,” Gertz defined.
Textual content-based LLMs are used solely as help instruments, for instance, to assist clients navigate literature on generated molecules. “They’re not our core know-how,” Gertz mentioned. “We’re not tied to a single structure. We use LLMs, diffusion fashions, conventional machine studying, and statistical strategies when it is smart.”
“Our imaginative and prescient is that each life-science group will use Converge Bio as its generative AI lab. Moist labs will all the time exist, however they’ll be paired with generative labs that create hypotheses and molecules computationally. We wish to be that generative lab for your complete trade,” Gertz mentioned.
