Coatue Data Science Head Alex Izydorczyk Is Leaving the Company – Business Insider

  • Coatue head of data science Alex Izydorczyk is leaving the hedge fund, following a leave of absence.
  • Izydorczyk was a rising star at the fund who became head of data science in 2016 at age 23.
  • A quant fund he oversaw was shuttered last year. 

Former rising star and data wunderkind Alex Izydorczyk is parting ways with Coatue Management, the $48 billion hedge fund where he’s led data science since 2016, according to sources familiar with the matter. 

Izydorczyk’s departure follows an extended leave of absence this year, the sources said, as well as a turbulent year in 2020 that saw the dissolution of the quant fund the young partner had overseen. 

It isn’t clear who if anyone will replace Izydorczyk, though his top deputy and head of quantitative research Justin Bleich remains at the firm. 

A representative for Coatue declined to comment. 

Izydorczyk first worked at Coatue as an intern in 2014 while he was still an undergrad at the University of Pennsylvania. He impressed billionaire founder Philippe Laffont and joined the firm full time after graduation. 

A talented statistician and coder, Izydorczyk helped launch the firm’s data-science efforts, transforming troves of data sets, often raw and unstructured, into value for the broader fund, both the public trading side and the private investing side. He became head of the promising new division at age 23. 

But cultural issues festered under his leadership and the division saw numerous departures, Insider previously reported. Former employees accused Izydorczyk of fostering a miserable workplace with a brash, mercurial management style that featured micromanagement as well frequent outbursts and insults directed at subordinates who upset or disappointed him. 

A quant fund led by Izydorczyk with more than $350 million in client funds hit bumps in 2019 and 2020 and was mothballed in summer of 2020 amid lackluster performance, Insider previously reported. 

Izydorczyk remained at the firm, but earlier this year he took an extended leave of absence, people familiar with the matter told Insider.
