Billionaire Alex Gerko, founder of quantitative-trading firm XTX Markets, has set up a personal investment firm to help manage his rapidly growing fortune.

Cromulon Capital was incorporated this year at the same London address as XTX, one of the world’s top market-makers along with Ken Griffin’s Citadel Securities, according to UK registry filings. It’s controlled by a similarly named firm that Gerko oversees along with XTX executives and Nikolajs Smirnovs, 38, whose LinkedIn profile lists his role as chief executive officer for a family office.
