Aug 2025Undisclosed stageAMD Ventures (lead)$48MSomite.ai is a Boston-based company pioneering foundation models for human stem cells to accelerate novel cell therapies, using a capsule-based data generation platform that produces differentiation data at 1,000x lower cost than traditional methods, enabling large-scale predictive models for cell-state transitions and regenerative medicine. The company announced a strategic investment from AMD Ventures on August 20, 2025, following its $47 million Series A funding round led by Khosla Ventures in May 2025; this collaboration integrates AMD Instinct GPUs to boost compute power for training foundation models and optimize software for biological data. Somite.ai's full-stack approach spans data generation, model training, and application discovery for high-impact cell therapies, aiming to drastically reduce development timelines and costs. Founded by Dr. Micha Breakstone (co-founder of Chorus.ai, acquired for $575M), the Head of MIT's Fundamental AI Group, and three National Academy of Science members, the company launched operations in January 2024 and has raised approximately $60 million to date. The AMD Ventures investment positions Somite at the forefront of computational biology, likened to revolutions in language and vision AI, with joint efforts to advance next-generation foundation models for cell therapy.

Martin Chavez; Ajinomoto; TechAviv; Fusion Fund; Harpoon$47MSomite AI, a TechBio company, develops DeltaStem, a foundation model and platform using proprietary AI and capsule technology to accelerate human cell therapy development by generating cell state transition data at 1000x greater efficiency than existing methods. The company targets therapeutic programs including beta cells for type 1 diabetes, articular cartilage for orthopedic applications, satellite cells for muscular diseases, and hematopoietic cells for blood disorders. Co-founded by Dr. Micha Breakstone (previous founder of Chorus.ai, acquired for $575 million) and Dr. Jonathan Rosenfeld (Head of Fundamental AI Group at MIT), Somite positions itself to create an 'AlphaFold moment' for developmental biology, enabling scalable production of human cells. On May 13, 2025, Somite AI closed its Series A funding round, raising more than $47 million, led by Khosla Ventures, with participation from SciFi VC, Chan Zuckerberg Initiative, Fusion Fund, Ajinomoto Group Ventures, Pitango HealthTech, TechAviv, Harpoon Ventures, and angels including R. Martin Chavez (former Chairman of Recursion) and Fidji Simo (outgoing CEO of Instacart). This round brings total funding to roughly $60 million, including prior investors like Texas Venture Partners. The funds will accelerate DeltaStem platform development and lead therapeutic programs, aiming to make cell therapies faster, cheaper, and more reliable. Vinod Khosla highlighted Somite's potential to reshape cell therapy through AI foundation models. Post-Series A, Somite announced a strategic investment from AMD Ventures to leverage AMD Instinct GPUs for training its models, enhancing data generation and software tools for biological data.

Founded in October 2023 by Micha Breakstone and Jonathan Rosenfeld, the company aims to become the OpenAI of stem cell biology. The founding team includes experts in developmental biology, stem cells, and computational biology such as Dr. Olivier Pourquie, Dr. Allon Klein, and Dr. Cliff Tabin. Somite raised $5.3 million in a pre-seed round led by TechAviv, with participation from Next Coast Ventures, Trust Ventures, Texas Venture Partners, Lerer Hippeau, and others. The funds support development of the AlphaStem AI platform, building Somite labs, and advancing the first therapeutic asset to phase 1 clinical trials. Six months later, Somite secured a $4.8 million extension, bringing total pre-seed funding to $10 million, with new investors including Astellas Venture Management and Montage Ventures joining as board observers. The extension funding will generate data to train AlphaStem, advance SMT-M01 toward the clinic, initiate SMT-B01 for metabolic disorders using brown adipocytes, and explore hypoimmune cell lines. Somite has secured intellectual property for patents and acceptance to Blavatnik Harvard Life Labs.
