Hi Hunter,

So great to see you on Saturday!  I loved connecting with you and hearing more about what your family is catalyzing in its impressive moon shot to cure cancer.  With such promising advances in the field and with a well-coordinated effort, it is not a stretch to believe that cancer can be transformed into a manageable disease in the relatively near-term.  To that end, I am attaching a brief overview of Hinge Bio.  The technology inventor, Dan Capon, has an impressive track record predicting the next advances in biotech and reducing them to practice.  Dan has been developing the technology platform for Hinge for more than 8 years, and it has more potential than all of his past inventions combined.  

We are raising a $2M “friends & family” seed round to progress several products, including a cooperatively-binding bispecific checkpoint inhibitor that has greater efficacy than two standard (non-cooperative) checkpoint inhibitors as well as a novel approach for conjugating chemotherapeutic “warheads” to cancer-seeking antibodies.  We are also priming a few select biotech VCs for the Series A and are in discussions with pharma companies.  

Dan knows of Patrick Soon-Shiong.  If Hinge is something Patrick or others in the brain trust would be interested in learning more about, we would be thrilled to discuss in more detail.  

My enthusiasm for this aside, it was wonderful getting together!  I hope to see you again soon.

Warmest regards always,
