Alameda Research co-CEO Sam Trabucco steps down, Caroline Ellison to become sole manager

After co-leading the company since 2019, Trabucco says he will be an advisor, but not a daily presence in a Twitter feed winding announcing its decision.

Alameda Research co-CEO Sam Trabucco announced his resignation Wednesday on Twitter. Trabucco said co-CEO Caroline Ellison will become CEO and he will remain in an advisory capacity. Alameda Research is the quantitative trading company founded by FTX crypto exchange founder Sam Bankman-Fried in 2017.

In a lengthy thread titled “On Happiness,” Hong Kong-based Trabucco said his appointment as co-CEO of Alameda Research last year “was to align titles with the reality", and that his resignation had the same objective. Trabucco and Ellison succeeded Bankman-Fried as head of the company.

On happiness:

Trabucco was appointed to the role in August 2012, having worked as a trader at Alameda Research since 2019. He graduated from Massachusetts Institute of Technology in 2015, a year after Bankman-Fried, and worked as a trader for Susquehanna International Group before being hired at Alameda Research.

Trabucco, who was named to Forbes magazine's 30 under 30 list during his tenure as co-head of Alameda Research, wrote that he had reduced his role at the company over the of the last few months and that he wouldn't have "a good day- presence today", adding:

"Spending 'normal' time at work is tricky, especially when you're trying to be a leader. […] I needed to relax, and I'm really, really happy."

Trabucco said he had no immediate plans after his departure, but mentioned that he had bought a boat.
