Strand AI

Strand AI is a Y Combinator-backed company that multimodal foundation models to predict uncollected patient biology. The company participated in the Winter 2026 batch of Y Combinator.

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.

Strand AI was part of Y Combinator's Winter 2026 cohort, has a team of approximately 2 employees, and is actively operating.
