The next generation of single-cell models.
F15 Labs is building the next generation of single-cell frontier models in biology — foundation models that learn from cellular atlases to understand cell states, predict perturbations, and accelerate discovery.
Models
Frontier models for single-cell biology
We're training the models that will define how biology is read at cellular resolution — from raw expression profiles to actionable predictions.
Foundation models
Pretrained on large-scale single-cell atlases — scRNA-seq, spatial, and multiome — to capture gene regulation, cell identity, and tissue context.
Cell state understanding
Rich embeddings for annotation, trajectory inference, and cross-dataset integration — turning millions of cells into interpretable biological insight.
Perturbation prediction
Simulate drug, genetic, and environmental perturbations at single-cell resolution — predict how treatments reshape cell populations before the experiment.
Approach
From atlases to insight
Curate
Aggregate and harmonize single-cell datasets across tissues, species, and modalities — building the atlases our models learn from.
Train
Scale foundation model pretraining on billions of cells — learning gene programs, cell-type hierarchies, and perturbation responses.
Discover
Deploy models for embedding, annotation, and perturbation prediction — giving researchers tools to move from data to hypothesis faster.
Stack
Built on the best of single-cell and AI
We combine state-of-the-art single-cell methods with frontier model architectures — pretrained on atlases, fine-tuned for your biology.
Expression & sequence
Gene-level transformers and variational autoencoders trained on transcriptomic profiles across tissues and conditions.
Scale & pretraining
Distributed training on curated single-cell atlases — harmonized metadata, quality control, and cross-dataset integration at billion-cell scale.
Inference & discovery
Embedding APIs, perturbation simulators, and evaluation pipelines — so researchers get answers, not raw matrices.
