About Strand AI
Summary
Strand AI builds multimodal foundation models that predict biological data missing from patient tissue samples. Its first product, Lattice, generates spatially resolved protein expression maps from standard H&E slides, replacing the need to run multiplex immunofluorescence staining on archival tissue. Pharmaceutical companies use the output to identify better-matched patients for clinical trials and to run retrospective studies across entire sample archives.
Business model
Per-project fee for end-to-end computational processing of submitted slides
Go-to-market
Pharmaceutical and research teams submit slides directly to Strand AI, which runs the analysis as a managed dry-lab service with no software to install or operate on the customer side.

Multimodal foundation models to predict uncollected patient biology
Strand AI develops foundation models to generate missing bio-data about patients. With this imputed data, pharmaceutical companies can select better patients for their drug trials and shave months from their drug launch timelines. We’ve already trained a multimodal foundation model that integrates spatial biology modalities, beating SOTA at a fraction of the cost.
