## BioStack's Seed Round and Data Network

BioStack creates workflows that bring together clinical information across disparate health systems and geographies, connecting notes, labs, imaging, medications, treatments and outcomes. The company said the round will support its continued expansion across the United States and international markets, development of its technology platform and growth of its engineering and research teams.

"Collecting every event linked to each patient enables a view of what happens at each stage of a patient's journey," said Sanat Mishra, co-founder and CEO of BioStack. "We're building the infrastructure that connects all of the clinical information and makes it useful, both for clinicians making decisions today and for the researchers and AI developers building the future of medicine."

BioStack creates proprietary datasets from de-identified data it collects from each provider system, which can support medical research, drug development and the training and evaluation of healthcare AI models. In India, BioStack is helping connect cancer patients with an investigational cancer vaccine program. The company has combined more than several hundred thousand fragmented X-Rays, MRIs, CT scans with other pathology and clinical records.

"The next frontier of healthcare AI will depend not only on better models, but on access to high-quality, longitudinal data that reflects how patients are treated over time," said Pushpak Kedia, Vice President at [Peak XV](https://akta.pro/company-profiles/0000023/peak-xv-partners). "Sanat and the BioStack team are building critical infrastructure that connects fragmented clinical information and transforms it into a valuable resource for clinicians, researchers and AI developers."

Peak XV Partners' Surge 12 cohort, unveiled on September 29, 2026, included 18 startups with an investment ceiling of up to $5 million per company, up from $3 million, TechCrunch reported. The firm invested over $50 million across the cohort, which has collectively raised over $90 million in seed funding.
