XTIUM is a next-generation, security-first managed services provider (MSP) headquartered in Tampa, FL, created from the November 2024 business combination of ATSG (managed IT/infrastructure) and Evolve IP (cloud/UCaaS), which rebranded under the XTIUM name in March 2025 (the Evolve IP brand continues in EMEA from its UK/Cardiff operations). XTIUM serves 1,700+ mid-size and enterprise customers (~950,000 users) with UCaaS, CCaaS, Desktop-as-a-Service/VDI, managed SD-WAN/SASE, managed security (MDR/XDR with Microsoft Sentinel, CrowdStrike, Fortinet, Palo Alto), dedicated cloud/IaaS, and managed IT — with deep native Microsoft Teams and Cisco Webex integration. It is PE-backed (RunTide; Evolve IP was historically backed by Great Hill Partners), channel-led, and led by President & CEO Russ Reeder.
