10x Science Raises $4.8 Million Seed Round for AI Protein Characterization Platform

In a press release, 10x Science announced it has closed a $4.8 million seed funding round led by Initialized Capital, with participation from Y Combinator, Civilization Ventures, Founder Factor, and several angel investors. The company is building AI systems for molecular-level protein characterization across the life sciences sector.

The platform developed by 10x Science automates and explains molecular insights that currently require months of manual analysis. It reasons across large datasets of mass spectrometry results to identify molecular forms and chemical modifications, enabling faster and more accurate characterization of protein therapeutics.

Founded in December 2025 by David Stephen Roberts, Andrew Reiter, and Vishnu Tejus from Professor Carolyn Bertozzi’s laboratory at Stanford University, 10x Science aims to address the growing demand for protein characterization in drug development. The company’s AI architecture features deep memory, allowing it to learn from each dataset and provide explainable, traceable results suitable for regulated environments.

The funding will be used to expand the engineering team and strengthen collaborations with pharmaceutical and biotech partners. 10x Science plans to extend its platform’s applications beyond drug development to fields such as cancer biology, neurodegeneration, and infectious disease research.
