Blue Owl Digital Infrastructure Trust Names Jack Viellieu Chief Operating Officer
The incoming COO steps up from Blue Owl’s digital infrastructure investment team as Bradley Berkley departs on amicable terms.
July 1, 2026
Blue Owl Digital Infrastructure Trust has appointed Jack Viellieu as its chief operating officer, effective June 30, 2026. The move fills the seat vacated by Bradley Berkley, whose resignation took effect the same day. The company noted that Berkley’s departure did not stem from any disagreement over its operations, policies, or practices.
Viellieu arrives in the role from within the Blue Owl organization rather than through an outside search. He serves as a managing director at Blue Owl and sits on the firm’s digital infrastructure investment team, where his work centers on sourcing new investments, managing the existing portfolio, and pursuing monetization opportunities. That background aligns closely with the trust’s mandate as a non-traded vehicle focused on digital infrastructure real estate.
Background
His path to the position runs through IPI Partners, the firm that preceded Blue Owl’s digital infrastructure strategy and was folded into it. Viellieu joined IPI as a director in July 2019. Before that, he worked as a private equity associate at Madison Dearborn Partners, a Chicago-based generalist fund, where he assessed and oversaw investments across six industry verticals, including telecommunications and technology services. He began his career as an investment banking analyst in the retail and consumer products group at Credit Suisse.
Viellieu holds an M.B.A. from the University of Chicago Booth School of Business and a bachelor’s degree in economics, earned magna cum laude, from Middlebury College.
Governance Details
The company indicated that Viellieu’s selection was not tied to any arrangement or understanding with another party, that he has no family relationships with the trust’s directors or executive officers, and that there are no related-party transactions between him and the company requiring disclosure.
The leadership change follows the trust’s most recent operational update, when Blue Owl Digital Infrastructure Trust reported approximately $1.92 billion in net asset value and an 11-property portfolio as of the end of April 2026. The elevation of an executive from the deal team, rather than an external hire, points to continuity in how the vehicle intends to run its investment and asset-management functions.
