Large organizations can struggle in high-tech environments that prize innovation and speed of execution. Conversely, smaller, agile entrants lack geographical reach and leverage. Tanuja Randery brings experience on both sides of the divide — and financial services expertise — to London-based BT Global Services, a £7 billion ($11.8 billion)–in-revenue unit of £18.3 billion telecommunications giant BT Group. Before becoming president for strategy and marketing in November, reporting to BTGS chief executive Luis Alvarez, Randery spent nine years with European data and communications service company Colt Group, the last two as CEO of MarketPrizm, which Colt acquired from Nomura Holdings and its Instinet agency brokerage in 2011. Under Randery, a former McKinsey & Co. consultant who engineered that deal, MarketPrizm grew from 20 to 60 people — pint-size next to BTGS’s 17,000 — and became a global leader in trading and data infrastructure services and low-latency connectivity. “You don’t need a lot of overhead to run a successful fintech business,” says Randery, 47, though the affiliation with Colt, a Fidelity Investments private equity holding, established credibility with a client base that includes major banks and exchanges. BTGS offered “a chance to scale up” and stay close to the “global banking vertical,” one of Randery’s current areas of focus, “at a time of significant acceleration in the pace of change.” Among BT’s brands are Netrix, whose trading-floor turrets are used by 68,000 traders at 800 firms worldwide, and Radianz Cloud, the latest iteration of a multipurpose network, acquired from Reuters Group in 2005, that reaches 11,000 financial industry end points.
