R eed Jobs was 12 when his father, Apple founder Steve Jobs, received a harrowing diagnosis: pancreatic cancer. Yosemite is now invested in some 20 companies, including gene therapy firm Tune Therapeutics and AI drug development startup Chai Discovery. “He wants to do big things and be impactful.” Tune recently raised $175 million, and Jobs has been involved since his time at Emerson.

But the potential for making a difference in cancer research and treatment drew him back.
