AI molecular discovery unicorn ($1.3B valuation). 100x improvement in de novo antibody design success. Backed by OpenAI. Eli Lilly partnership. Founded 2023, SF. $225M+ raised.
Chai Discovery is an AI-driven molecular discovery company founded in 2024 and headquartered in San Francisco. The company was spun out of research conducted by scientists with backgrounds at leading computational biology and AI organizations, with the founding mission of applying the latest advances in generative AI to accelerate drug discovery — particularly the historically difficult challenge of designing novel antibodies and small molecules from scratch rather than optimizing known chemical scaffolds.\n\nChai's core technology is a foundation model for molecular structure prediction and de novo design that operates across proteins, small molecules, nucleic acids, and their complexes. The company's flagship research achievement is a reported 100-fold improvement in de novo antibody design success rates, enabling the generation of functional antibody candidates without requiring extensive experimental screening campaigns. Chai Discovery has established a research partnership with Eli Lilly, one of the world's largest pharmaceutical companies, to apply its platform to therapeutic target programs. The company is backed by OpenAI, reflecting the deep connection between large-scale AI modeling techniques and the biological sequence-structure-function prediction task.\n\nChai Discovery reached a $1.3 billion valuation within its first year of operation, an exceptionally rapid ascent reflecting the strategic premium investors place on AI-native molecular discovery platforms. The company operates at the intersection of structural biology, generative AI, and therapeutic development, competing with platforms like Isomorphic Labs, Recursion, and Insilico Medicine in the race to demonstrate AI-designed drugs in human clinical trials.
Serverless GPU cloud platform for AI/ML with Python-native deployment and per-second billing; developer-favorite scaling from zero competing with Replicate and Beam for AI compute.
Modal is a serverless cloud computing platform purpose-built for AI and machine learning workloads — providing on-demand GPU compute that scales instantly from zero with per-second billing, container management, distributed training support, and a Python-native developer experience that makes running ML workloads in the cloud feel as simple as running code locally. Founded in 2021 in New York City and backed by Redpoint Ventures and other investors, Modal has grown rapidly as AI development has accelerated demand for flexible, developer-friendly GPU infrastructure.\n\nModal's developer experience is its primary differentiator — engineers write Python functions decorated with @modal.function() and deploy them to the cloud with a single command, with Modal handling container building, GPU provisioning, auto-scaling, and execution. The platform supports training jobs that need distributed compute across multiple GPUs, model serving endpoints that scale to zero when unused (eliminating idle GPU costs), and batch inference jobs that process large datasets. The per-second billing model means developers pay only for actual compute time, not provisioned instances.\n\nIn 2025, Modal competes in the AI infrastructure market with Replicate, Beam, Banana, and major cloud providers' managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless GPU compute. The market for AI-specific cloud infrastructure has grown dramatically as the number of ML engineers deploying models to production has expanded — traditional cloud providers require significant DevOps expertise to use GPU instances effectively, while Modal's Python-native approach reduces the barrier to entry. Modal has attracted a strong developer following among AI researchers and ML engineers building production AI applications. The 2025 strategy focuses on growing the developer community, adding enterprise features (dedicated GPU capacity, private networking, compliance), and expanding the hardware options available (H100 GPUs, custom accelerators).
