b12 Labs
b12 Labs is a San Francisco startup (Y Combinator S25) building AI agents for pharmaceutical and biotech chemistry. Its platform designs synthesis routes, plans and optimizes reactions, and turns those plans into robot-ready code for automated labs, aiming to compress early-stage drug discovery from years to months. The company was founded in 2025 by chemists Zlatko Joncev and Andres Bran, who met at EPFL's Lab of Artificial Chemical Intelligence.
Actithera
Actithera is a radiopharmaceutical biotech developing next-generation radioligand therapies (RLTs) for cancer. Founded in 2021 by medicinal chemist Andreas Goutopoulos and based in Cambridge, Massachusetts and Oslo, Norway, the company uses a proprietary, chemistry-led platform to design covalent small-molecule radioligands that lodge inside tumors, deliver targeted radiation, and clear quickly from healthy tissue. Its isotope-agnostic approach is engineered to match the residence time of a drug in a tumor to the half-life of long-lived radionuclides, with a lead program targeting Fibroblast Activation Protein (FAP). Actithera raised an oversubscribed $75.5M Series A in July 2025.
Scorpion Therapeutics
Scorpion Therapeutics was a Boston-based, clinical-stage precision oncology company built to advance what it called "Precision Oncology 2.0" - pairing cancer biology, computational chemistry, medicinal chemistry and genomics to design small-molecule drugs against cancer targets that had resisted earlier approaches. Founded in 2020 by a group of prominent scientists and biotech operators, it raised more than $440 million and built a pipeline of mutant-selective inhibitors, most notably the PI3K-alpha inhibitor STX-478 and a franchise of fourth-generation EGFR inhibitors. In January 2025 Eli Lilly agreed to acquire the company and its PI3K-alpha program in a deal worth up to $2.5 billion, while Scorpion's remaining pipeline and staff were spun into a new independent company, Antares Therapeutics.
Drug Hunter
Drug Hunter is a Boston-based knowledge platform for the scientists who turn molecules into medicines. Founded in 2018 by former Genentech chemist Dennis X. Hu, it distills scientific literature, patents, and early disclosures into searchable, expert-curated insights - molecule search, patent search, courses, flash talks, and a mobile app. More than 200 R&D organizations, including Eli Lilly, Biogen, Merck KGaA, Isomorphic Labs, and the NIH, rely on it. In September 2025 the company raised a seed round led by Teamworthy Ventures.
Augustine Therapeutics
Augustine Therapeutics is a Belgian clinical-stage biotech spun out of VIB-KU Leuven that is building a next-generation class of selective HDAC6 inhibitors for chronic diseases. Using a proprietary non-hydroxamate, non-hydrazide chemotype, the company designs molecules that block HDAC6's harmful catalytic activity while sparing its beneficial functions - aiming to avoid the toxicity that stalled earlier inhibitors. Its lead candidate, AGT-100216, is the first selective HDAC6 inhibitor to enter the clinic for Charcot-Marie-Tooth disease, with a pipeline extending into neurodegenerative and cardio-metabolic indications.
CaaMTech
CaaMTech is an Issaquah, Washington drug discovery company building patentable, psychedelic-inspired medicines. Founded in 2016 by chemist and patent attorney Andrew Chadeayne, it has synthesized and characterized a large library of novel tryptamines, solved crystal structures of compounds like 4-AcO-DMT and norpsilocin, and filed more than 100 patent applications. The company studies the 'entourage effect' in magic mushrooms to engineer compounds that keep the benefits while reducing side effects, and in 2021 raised a $22M Series A to push lead candidates toward human trials.
Neomorph, Inc.
Neomorph is a San Diego clinical-stage biotech building molecular glue degraders - small molecules that recruit the cell's own disposal machinery to destroy disease-driving proteins long written off as 'undruggable.' Founded in 2020 out of Deerfield Management with scientific founders who decoded how thalidomide-class drugs work, the company has assembled what it calls the world's largest proprietary molecular glue target space across a broad portfolio of E3 ubiquitin ligases. It has signed multibillion-dollar discovery pacts with AbbVie, Novo Nordisk, and Biogen, dosed its first patient with lead candidate NEO-811 in kidney cancer, and raised roughly $209M across Series A and B.
Synnovation Therapeutics
Synnovation Therapeutics is a Wilmington, Delaware precision medicine company building small-molecule cancer drugs aimed at validated oncology targets where greater potency and selectivity could beat the current standard of care. Founded in 2024 by a team of former Incyte medicinal chemistry leaders, it launched with a $102 million Series A led by Third Rock Ventures. Its lead programs are SNV1521, a CNS-penetrant, highly selective PARP1 inhibitor, and SNV4818, a mutant-selective PI3K-alpha inhibitor whose subsidiary Pikavation Therapeutics was acquired by Novartis in March 2026 for $2 billion upfront.
Blue Oak Pharmaceuticals
Blue Oak Pharmaceuticals is a Waltham, Massachusetts biotech founded in 2016 to discover the next generation of drugs for brain disorders. Led by neurobiologist and former Eli Lilly and Sunovion executive Tom Large, the company designs novel, CNS-focused 'privileged chemotypes' and pairs them with systems-neurobiology behavioral assays and AI to hunt first-in-class small molecules for schizophrenia, bipolar disorder and treatment-resistant depression. Its work runs through partnerships with phenotypic-screening firm PsychoGenics and AI drug-design company Exscientia.
Inductive Bio
Inductive Bio is a New York-based AI company building a machine learning platform that predicts how small-molecule drugs will behave in the body before they are ever synthesized. By training models on a pre-competitive data consortium shared across biopharma teams, its Beacon models, Compass software, and Indy chemistry assistant help medicinal chemists nominate better development candidates faster - reducing the costly 'whack-a-mole' of balancing potency against ADMET properties in preclinical drug discovery.
