Igor Tulchinsky has made a fortune in the of quantitative investing.

The 59-year-old, who immigrated to the U.S. as a child from Belarus, owns WorldQuant, which now manages $10 billion for billionaire Izzy Englander’s hedge fund Millennium Capital Management.

Whether it’s Trump’s see-sawing tariffs policy or a tech company’s quarterly earnings report, there’s likely a WorldQuant alpha calculating how to make money from it. “We trade the ripples, not the waves,” says Tulchinsky.

Now Tulchinsky wants to turbocharge his alpha factory by , which he believes can help build new and better algorithms.
