A new startup in NYC aims to improve the diagnosis and treatment of cancer.

Marty Chavez walked away from Goldman Sachs in late 2019. Now, he’s sitting on the board of artificial intelligence startup Paige. The New York-based firm uses AI to detect, diagnose, and improve the treatment of cancer.

“I’ve been drawn to the intersection of life sciences and computer science for a very, very long time,” Chavez told CNBC last week. “I imagined even back then that if you could take a radiology scan and give it to a computer, it would tell you whether it was a pathology or not.”

Paige launched in February 2018 under the direction of two doctors from Memorial Sloan Kettering Cancer Center. The startup closed a $25 million round at that time with leadership from Breyer Capital. The firm went on to raise another $45 million last year.

Though he did not invest in the firm, Chavez holds a Ph.D. in Medical Information Sciences from Stanford University.

“I’m thrilled at the opportunity to put my experience at the crossroads of math, data, software, and machine learning to work for the crucial mission of revolutionizing cancer prognosis and treatment,” Chavez said in a statement last week. “I’m looking forward to joining Paige’s team in driving forward computational models for human tissue, while building a world-class culture of engineering, data science, and clinical decision analysis.”

Chavez departed Goldman Sachs in September. He was the first of several high-profile departures from the firm.
