In this episode, we go inside the creation of Xaira Therapeutics — the biotech startup that raised over a billion dollars at launch without a product or clinical data.

Speaking with Vik Bajaj, CEO and co-founder of Foresite Labs (and one of the people behind Xaira’s creation), Surani explores how Xaira’s approach could redefine biotech company building, why it’s different from typical AI hype, and what makes it such a bold bet.

We follow Vik’s journey from academia to Google to Grail, and then into biotech investing with Foresite Labs, uncovering how a unique incubator model led to Xaira’s launch. From the big idea to the billion-dollar financing, we unpack what’s really happening behind the headlines.
