Atavistik Bio is a Cambridge, Massachusetts clinical-stage biotechnology company that discovers precision allosteric small-molecule medicines. Its proprietary AMPS (Atavistik Metabolite-Protein Screening) platform, paired with an AI-enabled discovery engine, uses natural metabolites as bait to reveal hidden allosteric pockets on disease-driving proteins that conventional drug discovery cannot reach. The company is advancing an oral AKT1-selective inhibitor for hereditary hemorrhagic telangiectasia (HHT) and a JAK2 V617F mutant-selective program for myeloproliferative neoplasms (MPNs).
CREATE Medicines is a Cambridge, Massachusetts clinical-stage biotech building in vivo immune programming - therapies that use an mRNA-lipid nanoparticle platform to turn a patient's own T cells, NK cells, and myeloid cells into chimeric antigen receptor (CAR) cells directly inside the body, rather than extracting and re-engineering them in a lab. Formerly Myeloid Therapeutics, the company rebranded in October 2025 as its pipeline expanded beyond myeloid cells and cancer into autoimmune disease and fibrosis. Its repeat-dosable, off-the-shelf approach aims to make CAR therapy cheaper and more scalable than conventional cell therapy, and the company says it has dosed more than 50 patients - among the largest clinical datasets for in vivo CAR to date.
Convergent Therapeutics is a clinical-stage biotechnology company in Cambridge, Massachusetts developing next-generation targeted radiotherapies for cancer. Its lead candidate, CONV01-α, is a PSMA-targeted monoclonal antibody linked to the alpha-emitting radioisotope actinium-225, designed to deliver tumor-killing radiation to metastatic castration-resistant prostate cancer while sparing healthy tissue. The technology, pioneered in the lab of PSMA-targeting pioneer Dr. Neil Bander and licensed from Cornell University, is led by oncologist Dr. Philip Kantoff.
Concerto Biosciences is a Cambridge, Massachusetts microbiome company that turns microbial ecology into health products. Its patented kChip platform screens millions of microbial interactions in nanoliter droplets to discover 'ensembles' - small, defined groups of microbes that work together to shepherd a damaged microbial community back to health. The company's lead program, ENS-002, is a topical live biotherapeutic for atopic dermatitis that suppresses Staphylococcus aureus without nuking the skin's helpful microbes. Founded in 2020 by scientists out of MIT and the Broad Institute, Concerto pairs ultra-high-throughput biology with AI to make microbial communities predictable and engineerable.
Delphia Therapeutics is a Cambridge, Massachusetts biotech pioneering a new field of cancer biology it calls activation lethality - the idea that cancer cells with oncogenic mutations live dangerously close to the upper limit of how much pathway activity they can tolerate, and can be pushed past it. Rather than blocking cancer signals like most drugs, Delphia designs targeted activators that overload cancer's stress pathways until the cell dies, aiming for durable benefit and a way around drug resistance. Founded in 2024 by Kevin Marks, Bill Sellers and Mike Dillon, it launched with a $67 million Series A led by GV, Nextech Invest, Polaris Innovation Fund and Alexandria Venture Investments.
Vesalius Therapeutics is a Cambridge, Massachusetts biotech founded by Flagship Pioneering that aims to reconceptualize how common diseases are understood and treated. Its premise: illnesses that drive roughly 90% of human disease burden are not single conditions but constellations of genetically and biologically distinct diseases. Vesalius uses AI, human genetics and genomics, and patient-derived iPSC cell models to spot hidden clinical patterns, trace them to causal gene circuits, and discover novel drug targets for conditions like Parkinson's, heart failure, type 2 diabetes, and Alzheimer's.
Vima Therapeutics is a Cambridge, Massachusetts clinical-stage biotechnology company developing VIM0423, a potential first-in-class once-daily oral therapy for isolated dystonia and Parkinson's disease. The drug selectively targets muscarinic cholinergic receptors in the brain to correct the dopamine-acetylcholine imbalance underlying these movement disorders. Incubated at Atlas Venture and led by neurologist Bernard Ravina, the company emerged from stealth in 2025 and has raised a $100 million Series A.
Crossbow Therapeutics is a Cambridge, Massachusetts biotechnology company building a new class of cancer immunotherapies. Its T-Bolt platform engineers TCR-mimetic antibodies - T-cell engagers that recognize tiny peptide fragments displayed on a cancer cell's surface (peptide-HLA complexes), opening up intracellular proteins that conventional antibodies cannot reach. The lead program, CBX-250, is a first-in-class T-cell engager in a Phase 1 trial for relapsed or refractory myeloid malignancies. Backed by more than $157M in venture funding, Crossbow aims to expand the universe of targetable cancer antigens.
Strand Therapeutics is a clinical-stage biotech building 'programmable' mRNA medicines - drugs engineered with logic circuits so they switch on the right protein, in the right cell, at the right time. Spun out of MIT in 2017 by synthetic biologists who wrote the first programming language for mRNA, Strand's lead candidate STX-001 is a self-replicating mRNA that makes tumors manufacture their own IL-12, turning cold cancers hot from the inside. Backed by Kinnevik, Regeneron, Amgen and Eli Lilly with over $250M raised.
