Cryptocurrency trading firm Portofino Technologies is experiencing another wave of senior staff departures, months after losing its chief financial officer and general counsel, according to people familiar with the matter.
Chief revenue officer Melchior de Villeneuve recently left the Swiss company, the person said, asking not to be identified because the matter is private. Chief of Staff Olivia Thurman confirmed that she has left the company.
Two senior developers, Olivier Labanas and Mike Trihorn, and two junior developers are also said to have left the crypto market maker. Mr. de Villeneuve, who joined in January, did not immediately respond to a request for comment, according to his LinkedIn profile. The same was true for Ravanus and Trihorn.
Portofino did not respond to multiple emailed requests for comment by the time of publication.
The company is having difficulty securing human resources. Cerin Armstrong, general counsel and compliance officer, left the company earlier this year. His departure follows that of Mark Blackborough, the company’s former chief financial officer, who stepped down in April.
Mr. Thurman has been with Portofino for approximately 18 months and joins from Centerview Partners.
Portofino raised $50 million in equity funding in late 2022. The company was founded in 2021 by former Citadel Securities leaders Leonard Lancia and Alex Casimo.
The Swiss company told CoinDesk in March that it was considering opening new offices in New York and Singapore.
