Ramaswamy received the grant in 2011. Roivant went public in 2021.
I’m sorry, What is your point? You speculated about a sole proprietorship. Since his biotech involvement started with investors that is not possible.
Vivek graduated from Harvard College in 2007 and worked for several years before law school at the hedge fund QVT Financial from 2007 to 2014. He was a partner and co-managed the firm’s biotech portfolio. Again no sole proprietorship. He was already worth <$1M when he matriculated.
