Drug discovery (2025)
Science on steroids

Drug discovery is a messy, painstaking and money sucking craft. AI startups promise to inject a little precision and cost saving.
The common way to dream up new drugs is to sift millions of chemical compounds against biological targets; hits from these screens are first tested in cells and then in animals and humans. Very occasionally, there are happy accidents, like when scientists discovered penicillin. But for the most part, success in this world is extremely elusive — designing a drug can take 12-15 years and cost some $1bn+. Nearly 90% of the experimental drugs that enter human clinical trials fail, according to Deloitte.
AI software helps by learning from patterns in medical data. Because this data is scientific and precise, “hallucinations” — i.e. mistakes and nonsense — are far less likely than with more broadly trained chatbots. Startups say their AI can scan millions of compound possibilities much more speedily than mere mortals (”turbocharge” is a commonly used verb to describe the AI effect). One banker likened the software to hailing an Uber, rather than needing to buy your own car.
“There is no more important application for AI than helping to improve human health,” according to Demis Hassabis, CEO of Google DeepMind spinoff Isomorphic Labs, which raised Europe’s biggest round ($600m) in Q1 2025. His company — its mission statement: “to solve disease” — wants drugs designed by AI in clinical trials by the end of the year.
Hassabis’s research on DeepMind’s protein prediction programme AlphaFold won him the Nobel Prize in 2024. Another founder capitalising on this work is Simon Kohl, who raised $50m for UK AI drug discovery startup Latent Labs this year. Unlike Isomorphic, which is partnering directly with pharma companies, Latent Labs will operate a service model, providing its AI platform to pharma companies so they can shave time off the discovery process.
The UK is home to other AI drug hunters, including Healx, which has nabbed $47m to identify new drugs for rare diseases. The company said that it has received regulatory clearance to start “phase 2” clinical trials for a new drug in the US later this year. Meanwhile, Cambridge University spinout CardiaTec raised a $6.5m seed round in 2024 to tackle cardiovascular diseases.
While we wait for the first drug made with help from AI to reach the market, there are a handful of standout cases where AI has unearthed new uses for older drugs. The New York Times reported last year of a man who looked likely to die as a result of a rare blood disorder. His girlfriend, on a whim, contacted a doctor who had told her he was working on AI drug discovery. The surprising, repurposed drug treatment combination that the doctor’s computer spat out saved the man’s life.

Interview with Meri Beckwith, cofounder, Lindus Health
After the preclinical drug discovery work is done, that’s when pharma giants take over. They operate clinical trials, which can take as long as seven years to navigate, at great expense.
Meri Beckwith believes this whole process can be done better and faster. He got the idea to overhaul drug trials after he saw first-hand just how flawed they were. This was 2020 and Beckwith — a former investor — had signed up to participate in several Covid-19 vaccine studies. “The experience was awful; the whole process was disjointed — how can the companies who run these things not build a functioning website? Why was it so messed up? That was the spark for me. I knew there was a lot to fix."
Clinical trials — which involve the recruitment of hundreds or maybe thousands of volunteers — are run on behalf of pharma companies by third-party entities called contract research organisations (CROs). “It’s a big, clunky industry. They have billable hours like law firms so no incentive to do things faster or better. Essentially it comes down to that,” says Beckwith.
Lindus Health wants to do things “radically faster” — 72.9% faster to be precise — and proudly calls itself an “anti-CRO”. Its pitch is that it can do everything in one, rather than requiring a pharma company to hire four or five different vendors to run a study. Lindus raised a $55m in Series B in January.
The response to this upstart company has been “generally positive”, Beckwith says. “They know they’re being screwed by CROs. Once they work with us, they can see it’s a totally different model of running research.” The best responses come from senior people who work for CROs. “The stuff they tell us about their industry is mindblowing,” Beckwith says.
When Lindus started out in 2021, “if we had tried then to go straight into working with big pharma, it would’ve been a disaster. We knew it was going to take a while to make progress, so we deliberately focused on non-drug trials initially”, which are studies that generally face fewer hurdles. The company has since expanded to drug studies.
But pharma companies — which have ingrained ways of doing things — don’t adjust to working with startups very easily. “There’s definitely a tug of war. You need to find a champion who will help shield you from the worst of the bureaucracy,” Beckwith says.
Still, it’s amazing how little has changed in the industry after the pandemic, Beckwith adds. “During Covid, things ran really quickly because they had to. It’s unbelievable the extent to which things went back to the way they were before,” he says. “I’m kind of amazed by it all still and the deference to precedent and the bureaucratic inertia that takes time to unwind. “And as a non-clinician myself, I do genuinely think that the industry massively over-eggs experience. You don’t need to know as much about this industry as people think you do.”

Sifted take
The true test for AI startups will be whether the drugs they help develop are more likely to be successful for patients than those developed by humans. For a reality check, AI’s effects on drug discovery so far have been “subtle but meaningful,” concluded researchers in a recent paper for Nature Medicine. But in an industry as complex as pharma, even subtle improvements are reasons for startups to celebrate.
