## About

R42 Group traces to 2004 when Dr. Ronjon Nag converted proceeds from his prior company sales into a dedicated investment vehicle. The structure combines family-office capital allocation with a venture fund and an institute that runs lectures and academic programs. R42 invests in AI, biotechnology and fintech. It commits to early-stage funds and executes direct co-investments alongside those funds. Confirmed activity spans seed and growth rounds across North America and Europe. Portfolio positions include companies developing AI drug-discovery platforms, blood-brain-barrier therapeutics and smart-city infrastructure. The office maintains a small principal team and draws on external scientific advisors. Dr. Nag holds an adjunct faculty appointment at Stanford and serves on boards including MIT Alumni Angels of Northern California and the Institution of Engineering and Technology. No material operational events have been recorded in the last 24 months.
