Portofino faces a new stability crisis within its leadership team

The crypto market maker Portofino Technologies is going through a tumultuous period marked by the successive departure of several key members of its management team. This new wave of turbulence comes less than six months after the loss of its CFO and legal advisor, revealing broader talent retention issues within the Swiss firm.

Accelerated hemorrhaging at the management level

According to sources close to the matter, Portofino recently lost two important figures in its leadership. Melchior de Villeneuve, Director of Revenue since January 2025, has left his position, while Olivia Thurman, who held the role of Chief of Staff for nearly eighteen months after joining from Centerview Partners, has confirmed her departure. These resignations are also accompanied by the departure of four developers: two senior, Olivier Ravanas and Mike Tryhorn, as well as two junior-level team members.

The pace of departures highlights structural difficulties at Portofino. CFO Mark Blackborough had already left the company in April 2025, followed a few months later by Celyn Armstrong, General Legal Counsel and Compliance Officer.

Portofino management disputes the characterization of departures

Leonard Lancia, CEO of Portofino, responded to the revealed information. In a correspondence sent after the publication of the initial report, he questioned how the departures were characterized, arguing that the terminology used “implies unilateral resignations,” which he believes “does not reflect the true nature of these departures.” The company has not provided additional details on the exact circumstances of these separations or the reasons behind the various departures.

Portofino also declined to comment directly on individual employment situations. Management requested that media coverage not suggest unilateral departures when other factors might be involved, without specifying which ones.

A context of organizational fragility for Portofino

These personnel movements occur in a context where Portofino struggles to stabilize its team. The firm, founded in 2021 by Leonard Lancia and Alex Casimo, both former Citadel Securities executives, raised $50 million in equity financing at the end of 2022. Despite these resources, the company appears to face significant challenges in talent retention.

In March, Portofino announced ambitious expansion plans, considering opening new offices in New York and Singapore. However, this growth strategy must now contend with ongoing internal instability within its leadership core. The simultaneous loss of leaders across different areas—finance, compliance, revenue, and technical development—raises questions about Portofino’s ability to maintain its growth trajectory and retain its key talents.

The accumulation of these departures over a relatively short period suggests that the crypto market maker must address deep internal issues to regain sustainable organizational stability.
