Gill Moves from London Stock Exchange's MillenniumIT to Torstone

Gill left MillenniumIT, the technology arm of the London Stock Exchange Group (LSEG), in April 2017. A spokesperson for the LSEG and Gill himself confirmed the departure.

Gill’s departure comes after the LSEG appointed Chris Corrado, an ex-MSCI and UBS executive, as its chief information officer and chief operating officer in 2015. Corrado replaced longtime tech head Antoine Shagoury. Under Corrado’s direction, the LSEG is undertaking a broad reorganization of its technology operations, according to people familiar with the situation.

Gill, who was formerly based in Sri Lanka at Millennium’s headquarters, has moved to London in order to assume the chief operating officer role at Torstone Technology, and will also join the board of directors. The appointment was confirmed by a Torstone spokesperson.

“Strengthening our board and management team is a key part of Torstone’s global expansion as we take our cross-asset platform to new regions and market segments,” says Brian Collings, CEO of Torstone. “We will benefit greatly from Mack’s extensive market and leadership experience as we build partnerships with other market participants around the world. Mack will also take an operational role in enhancing and scaling our client service and engagement.”

Prior to his time at the LSEG, Gill was the president of SunGard Technology Services, now FIS, where he spent just under 20 years. He also serves as a board member of the International Association for Quantitative Finance.

Gill’s move is not the first link between the LSEG and Torstone. In January, the LSEG announced that Torstone would connect its Inferno technology to its Approved Reporting Mechanism, UnaVista, in order to allow users to comply with new transaction reporting requirements under the Markets in Financial Instruments Regulation.
