Daniel Nadler is a Canadian entrepreneur best known as the founder and CEO of OpenEvidence, an AI company for physicians. The platform helps doctors search medical research and use clinical decision support tools. Before that, he cofounded Kensho Technologies, which built AI systems for financial intelligence. He studied mathematics, classics, and poetry at Harvard, then wrote a Ph.D. thesis on the pricing mechanisms of credit derivatives.
His wealth comes from building AI companies in finance and medicine. In 2018, S&P Global bought Kensho for $550 million after Nadler leased its software to Wall Street asset managers. He later cofounded OpenEvidence in 2022 to help doctors work through large amounts of medical research. Early 2026 funding valued OpenEvidence at $12 billion, and Nadler owns nearly 60% of the company.
How Daniel Nadler built his wealth
Nadler first made his name with Kensho Technologies, a company he cofounded in 2013 while he was still a Ph.D. student. Kensho used AI for financial intelligence and let users do financial analysis in a search-style format. Nadler leased the software to Wall Street asset managers. That business ended in a major deal when S&P Global acquired Kensho in 2018 for $550 million.
His bigger fortune is tied to OpenEvidence. He cofounded the company in 2022 to help doctors make sense of the huge volume of medical research. OpenEvidence is free for verified doctors and brings in revenue from advertising. The company has signed up more than 758,000 doctors and is adding 55,000 per month. After an early 2026 funding round, OpenEvidence reached a $12 billion valuation.
Forbes estimate and the company behind it
Forbes put Nadler's net worth at $7.6 billion on its real-time billionaires tracker as of October 20, 2026. That estimate fits the structure of his wealth, because he owns nearly 60% of OpenEvidence. With the company valued at $12 billion in early 2026, his stake is the main reason he ranks among the richest people in technology.
OpenEvidence also stands out for the size of its medical audience and the way it makes money. The service is aimed at verified doctors, which helps explain why adoption matters so much to the business. More than 758,000 doctors have signed up, and the company is adding 55,000 each month. Instead of charging those doctors, OpenEvidence earns money from advertising.
