Digital infrastructure leader Vertiv named Paul Ryan as President for Europe, Middle East and Africa (EMEA), effective 1 January 2026. 

Ryan succeeds Karsten Winther, who retires after driving EMEA strategy, operations and profitability through complex markets since joining in 2018. Karstenr supported the transition until 31 December 2025.

Giordano highlighted Ryan's internal promotion as reflecting Vertiv's high-performance culture and potential to accelerate growth.

Writing on LinkedIn, Ryan said he feels "very privileged to lead Vertiv’s EMEA organisation and incredibly excited by the limitless opportunities we share at such an important time in our industry, working closely with all our customers to deliver critical digital infrastructure at scale and at speed”. 

He prioritises customer closeness via local design, manufacturing and service, turning innovation into practical outcomes.

Ryan holds a Bachelor's in production management and a Master's in science (mathematics) from the University of Limerick, plus Kellogg executive training. Patrick Grainey has assumed acting Chief Procurement Officer duties.

Paul Costanzo

Job from: Director Mission Critical at Kais-AIR
Job to: Senior Director, Data Center Construction at Oracle

In a strategic hire for its cloud infrastructure expansion, Oracle has appointed Paul Costanzo as Senior Director of Data Center Construction. Paul joins from Kais-AIR, where he served as Director of Mission Critical, driving the firm's leadership in modular data centres, AI factories and high-efficiency cooling systems for Tier 2 and Tier 3 markets.

At Oracle, Paul will spearhead the engineering and delivery of hyperscale, AI-optimised data centre infrastructure critical to Oracle Cloud's next-generation compute and AI/ML platforms. His remit encompasses accountability for speed, scale, cost and reliability across expansive, multi-site programmes. 

Key priorities include hyperscale and AI-optimised delivery, high-density power solutions, advanced cooling technologies (such as liquid cooling), modular and off-site construction methods to hasten deployment, and rigorous risk, schedule and capital management at megaproject scale. 

He will provide cross-functional leadership spanning design, construction, supply chain and operations, with a clear mandate: build faster, scale smarter and deliver resilient infrastructure for the AI era.

Paul's prior role at Kais-AIR saw him unify data centre sales and engineering into a revenue-focused division, targeting high-margin opportunities through rapid, precision-engineered deployments. 

He forged strategic partnerships, secured flagship projects and positioned the company as a benchmark provider for mission-critical infrastructure amid surging AI demand. His expertise aligns seamlessly with Oracle's concerted data centre build-outs.

The hire underscores Oracle's commitment to bolstering its global data centre footprint to meet exploding AI workloads. Paul’s appointment reflects the industry's talent migration towards hyperscalers, accelerating AI-ready infrastructure.
