Operating Company

Vaultica runs carrier-neutral enterprise colocation in five European metros: Milan, Geneva, Copenhagen, Stockholm and Oslo. Its seven data centers serve telecom carriers, IT and cloud providers, and financial institutions. At MIL01 in Siziano and GEN02 in Gland, it sells colocation inside buildings that STACK still runs. It is building MIL03 in Settimo Milanese and plans MAD01 in Alcalá de Henares, near Madrid.

Infrastructure funds managed by Apollo own the company. Apollo agreed on 29 April 2025 to buy STACK Infrastructure's European colocation business from Blue Owl Digital Infrastructure. The carve-out closed on 13 August 2025. STACK had set up the colocation unit in 2024, and it kept its European hyperscale business. The carved-out business launched as Vaultica on 10 December 2025.
