Recursion

Decoding biology to radically improve lives. The industrial revolution of drug discovery is here.

"This is only possible because we control the design, make, and test steps within one connected system rather than handing off between disconnected tools and teams."

Once molecules are designed in silico, they must be synthesized and tested in the real world. In Part 7 of our platform series, VP of Pharmacology Martin Redhead, Ph.D., explains how these candidate designs move directly into our automated DMTL (Design, Make, Test, Learn) labs.

Recursion’s automated chemistry platform goes far beyond simple one-pot reactions. We execute complex, multi-step medicinal chemistry at scale. Advanced automation handles the workup, purification, and digital sample tracking for thousands of compounds, creating a digital record of every single experiment.

Our in-house AI agents take this a step further by actively helping scientists plan efficient synthetic routes. Because we control the entire design, make, and test lifecycle within one fully integrated system, we completely eliminate the friction and time lost handing off data between disconnected teams.

Recursion Announces New Clinical Data Across Two Potential First-in-Class Programs, Sanofi Partnership Milestone, and Oversubscribed $200M Offering

Today, we announced important progress across our clinical pipeline, partnerships, and capital position—reflecting growing evidence of what our integrated AI-enabled drug discovery platform can deliver.

🚀 REC-4881 | Deep, durable polyp reductions in FAP
In an expanded adult population (18+), 87% of patients achieved polyp burden reductions after 12 weeks (47% median), with 85% remaining below baseline after 12 weeks off treatment.

In the upper GI—the area of greatest unmet need—92% achieved reductions (55% median), including two patients with near-complete reductions (≥98%). Of those with reductions, 92% remained below baseline after 12 weeks off treatment.

With no approved pharmacologic therapies for FAP, we are targeting registrational trial initiation in 2H 2027, pending FDA discussions. Full data will be presented November 2 at CGA-IGC.

🚀 REC-1245 | Encouraging early activity in heavily pretreated cancer patients
Our potential first-in-class oral RBM39 degrader demonstrated three partial responses (two confirmed in endometrial cancer; one unconfirmed in liver cancer) and 91.7% disease control (11/12) at doses ≥45 mg. No dose-limiting toxicities or treatment-related serious adverse events were observed at the selected 45 mg expansion dose.

🚀 Sanofi | First development candidate optioned
Two challenging targets, one oral molecule. A potential first-in-class candidate for inflammatory disease, enabled by Recursion’s AI platform and small-molecule chemistry capabilities alongside Sanofi’s expertise.
Phase 1 expected in 2027, marking the sixth progress-based milestone across our collaboration.

🚀 $200M Oversubscribed Follow-On Offering | Extending Runway Into 2029
Broad demand from leading healthcare specialists, long-only institutions, and growth investors, including Janus Henderson Investors, Invus, Longaeva Partners, ARK Invest, and Driehaus Capital Management.

The financing supports advancement of our clinical pipeline, continued AI engine innovation, and strategic partnerships.

Multiple independent proof points. Across diseases, programs, and partnerships. Powered by one integrated AI-enabled engine.

"Our integrated system narrows millions of molecules down to a short list that's synthetically accessible. Not just promising in silico, but actually makeable before a single one is sent to the labs."

Traditional drug design often leans on decades of precedent and familiar chemistry. In Part 6 of our platform series, SVP of Drug Design Donovan Chin, Ph.D., explains how Recursion breaks that mold by getting a full computational design cycle up and running in about a day.

Our AI-native engine vastly increases the aperture for our chemists. Instead of relying solely on known binding pockets, they can efficiently explore entirely novel and complex chemical space. By leveraging our integrated data, the team can forecast non-obvious design hypotheses and predict how to synthesize molecules even when nothing like them currently exists.

This process begins by scoring binding affinity using advanced 3D structural models like Nesso-1. From there, the team runs hundreds of integrated models covering ADME, potency, advanced simulations, and AI retrosynthesis. This unified system rapidly filters millions of potential molecules down to a precise shortlist of high-quality candidates that are physically ready for the lab.

"Across our programs, we've advanced quality novel candidates after synthesizing only around 300 compounds, roughly 90% fewer than the industry average."

Now that we have mapped the biology, we need to design the exact molecule to target it. In Part 5 of our platform series, SVP of Drug Design Donovan Chin, Ph.D., and VP of Pharmacology Martin Redhead, Ph.D., break down how we transition from biological target discovery to navigating complex chemical space. Just like our approach to biology, we solve chemistry problems through a continuous feedback loop between computation and experimentation.

Before a single molecule is ever synthesized in the lab, our team uses Centaur, our integrated drug design environment. By combining hundreds of machine learning and physics-based models into a single platform, we can iteratively design novel molecular structures starting directly from target properties. This generative de novo design approach automatically updates our models so they improve with every single cycle.

Our AI-native product engine has already produced over 10 development candidates. By holding our chemistry to the same rigorous standards as our biology, we can synthesize a fraction of the traditional compound volume while delivering superior novel molecules. We believe this focus on quality and novelty over sheer volume will define the true impact of AI on drug development.

"A hypothesis from a model isn't a discovery yet. So, it goes back into the lab. The biology the model predicted is the biology we saw at the bench."

A computational prediction alone does not cure a disease. In Part 4 of our platform series, Associate Principal Scientist Celia Fernandez explains how Recursion closes the loop to turn AI generated hypotheses into validated biological targets.

Once our foundation models point to a potential target, we run the lab in the opposite direction. The hypothesis enters a validation cascade that becomes progressively more demanding and highly specific to the disease. This physical testing allows us to aggressively derisk our computational discoveries directly at the bench.

We test these targets against the exact same high bar that our global pharma partners hold their own internal programs to. When the loop finally closes, we can confidently prove that the biology the machine learning model predicted matches the physical reality we see in the lab.

“The data is used to train our models. The models point to the targets. That’s lab-in-the-loop.”

Generating millions of data points is only the first step. You need immense computational power to make sense of it (and maybe a good pair of headphones, because BioHive-2 is loud). In Part 3 of our series on our end-to-end platform, Chief Technology Officer Ben Mabey explains how Recursion turns raw data into a novel view of biology.

🖥️Using BioHive-2, one of the fastest supercomputers in the world, we train state-of-the-art foundation models to process every image and sequence we generate. These models create a unique embedding, or fingerprint, for every cellular perturbation we have ever performed. All of this high-dimensional data is compiled into a single massive dataset to form a comprehensive map of biology.

By comparing known disease fingerprints against this map, we can find other genetic manipulations that create similar effects. This allows us to identify targets that drive or rescue a disease state, generating new hypotheses and pointing us towards potential novel discoveries.

“This is the part that turns this from just a cell factory into a data factory. This high-dimensional data is the raw material our foundation models learn from. And because it’s this rich, the data is reusable, mined again and again across programs rather than generated once and thrown away.”

Growing disease-relevant cells at scale is only the beginning. In Part 2 of our series on our end-to-end platform, VP of Neuroscience Chris Winrow breaks down how we run genome-scale perturbations and quantify the resulting changes in cellular state.

🔬Using acoustic liquid handlers, we move 2.5-nanoliter droplets of CRISPR-Cas9 reagents into 1,536-well plates, up to 2 million times a week. Crucially, we intentionally randomize these experiments so our machine learning models learn true biology rather than experimental artifacts.

By imaging and sequencing these exact cells, we capture thousands of measurements from a single experiment. This creates a rich, reusable dataset that feeds our AI foundation models today and stays future-proofed for tomorrow.

🧠 “To build this genome-wide map, we had to create over 1 trillion neurons, roughly the equivalent of 12 human brains. There was no blueprint for this.”

To truly study a disease, you have to work with cells that actually resemble it. In Part 1 of our new series breaking down our end-to-end platform, CEO Najat Khan shares the unprecedented engineering required to map biology at an industrial scale.

Starting in 2021, we set out to grow human neurons at scale – executing systematic genome-wide perturbations, and capturing high-dimensional imaging. Using specialized proprietary protocols developed in partnership with Roche and Genentech, we kept these iPSC-derived neurons alive, consistent, and biologically representative.

We are already seeing the impact of this work, with Genentech having optioned the first neuroscience target from the collaboration into a joint early discovery program.

This is the foundation of high-dimensional target discovery.

🎙️Where AI is genuinely changing drug discovery and development — and where it isn't.

Recursion CSO Dave Hallett joined Patrick Short, CEO of @SanoGenetics and host of The Genetics Podcast for a conversation on the real gains and remaining hurdles for AI drug discovery and development. Drawing on his nearly 30 year experience, beginning at Merck in the mid-1990s, Dave shared how AI has fundamentally changed what’s possible  – from research capabilities, to molecule design, to clinical trial planning – but noted that it still can’t change the laws of physics.

🔹Highlights include:

▪️How AI has allowed for true multi-parameter optimization

Dave said the shift from single-parameter to true multi-parameter optimization is the biggest change he's seen at the bench. A person can hold roughly six or seven variables in their head at once, a computational system can track far more, without recency bias, across active learning loops. The result: "AI has massively compressed the time and the cost that's required to get from an idea to a candidate." Recursion has seen that show up as roughly 80% reductions in compounds made and 50-70% cuts to time-to-candidate on affected programs.

▪️Simulating trials before running them

Rather than copying existing clinical trial protocols, Dave shared how Recursion pressure tests inclusion and exclusion criteria through simulation before a study launches — asking which criteria are actually still fit for purpose. Applied to REC-7735, evaluated in the ZINNIA trial, that process expanded the pool of patients the trial could reach by approximately 20%.

▪️Looking forward with pragmatism and optimism

Dave was candid about AI’s limitations, too, noting that the industry is "still a long way" from modeling emergent human pathophysiology at the organism scale. He also discussed Recursion's partnership work on the breakthrough neuro map, and offered advice to early-career scientists: build deep domain expertise while remaining "bilingual" across biology, chemistry, and computation.

🚀 From data factory to better drugs: inside Recursion's AI-native product engine

In our new video, we take you behind the scenes of Recursion’s AI-native data factory and product engine – the first, and one of the largest, of its kind.

💠Capturing Cells AI Can Decipher

It starts with perturbing cells via CRISPR and other compounds — dozens of methods at nano scale, generating up to 2 million experiments a week. Recursion’s labs are built to randomize experiments so models learn what's real biology versus noise. Cells are imaged and sequenced at scale, yielding thousands of measurements per experiment — high-dimensional data that trains our foundation models and can be mined again and again.

💠Creating Maps of Biology

Our foundation models turn every perturbation — imaging, genetic, and patient data — into a unique fingerprint. Mapping these fingerprints lets us compare genetic manipulations, spot ones with similar effects, and generate new hypotheses for what drives or rescues a disease state.

💠De-Risking Discoveries & Designing New Drugs

We validate hypotheses at the bench against the same high bar pharma partners hold themselves to. Each target becomes a chemistry problem, solved in Centaur — our integrated design environment running hundreds of ML and physics-based models. Starting from target properties, we generatively design novel molecules, improving with each cycle.

A chemist can run a full design cycle in about a day, using tools like Nesso-1 and in-house AI agents to explore novel chemical space and plan design synthesis. Hundreds of models — ADME, potency, simulations — narrow millions of molecules to a short, makeable list. We’ve produced 10+ development candidates, and each held to that same high bar.

💠Synthesizing Compounds

Compounds move directly into automated testing. Scientists describe an experiment in plain language and the platform generates the protocol, cutting pharmacology costs roughly in half compared to industry. Every result feeds back into the models, letting us reach a development candidate with about 90% fewer molecules synthesized than industry average — one closed loop, built to make fewer molecules, not more.

💠Carrying Insights Into the Clinic

Clinical candidates enter our ClinTech platform. Our AI compares lab response data to real patient tumors to predict who benefits before enrollment even starts. Our Site Finder tool mines hundreds of millions of patient records to find high-quality trial sites in hours, improving enrollment 30–60% and slashing feasibility and startup timelines. Once running, a biometrics engine turns dose-escalation decisions that used to take 7–10 days into 24–48 hours.

This is an end-to-end AI-native product engine that has already put multiple programs in the clinic and is changing the way medicines are made.

🎉We won!

Proud to announce that Recursion has won a @FiercePharma AI Innovation Award for AI Innovation in Drug Discovery.

💠 The award recognizes the impact of the Recursion OS which connects biology, design, and clinical development into a single AI product engine.

They note that this engine is more than a collection of point solutions. “Instead of stitching together fragmented public datasets, Recursion generates its own proprietary data at industrial scale and feeds it directly back into the system.”

As CEO Najat Khan says: “It enables our scientists to generate and test hypotheses at a scale and resolution that simply wasn’t possible before, uncovering novel biology and designing more precise medicines faster for patients who are waiting. And it has delivered tangible proof points – including multiple drugs advancing in our internal clinical and pre-clinical pipeline, and ongoing milestones for pharma partners.”

Those proof points include REC-4881 for FAP (familial adenomatous polyposis). “REC-4881 marks the first potential treatment for the condition and the first clinical validation of the Recursion OS, backed by encouraging Phase 2 data,” they write. “The same platform also uncovered a novel mechanism for treating FAP – MEK 1/2 inhibition – and used real-world data to broaden patient eligibility for the trial.” 

We’ll be presenting additional Phase 2 data from the TUPELO trial at the Collaborative Group of the Americas on Inherited Gastrointestinal Cancer (CGA-IGC) Annual Meeting in November.

🚀 We’re thrilled to have won this recognition from Fierce and look forward to continuing to demonstrate proof points from both partnerships and clinical programs.
