Aptia has announced its formal launch following the management buyout of Mercer’s UK pension administration and US health and benefits administration businesses last year.
The firm - which will have around 1,100 clients supporting more than seven million people with health and wealth administration - was formed with the backing of Bain Capital Insurance last June and included more than 3,500 employees across the UK, US, India, and Portugal.
The business is headed by chief executive Bala Viswanathan, the former chief operating officer of Mercer, and group chair Dominic Burke, the former vice-chair of Marsh McLennan.
In preparation for its global launch, Aptia has made a series of senior appointments - hiring individuals including group president and chief administration officer Mike Methley; chief financial officer Chris Rayner, group chief information officer Imran Ali; group general counsel and company secretary Melissa Hetherington; and chief people officer Roopa Abraham Kochar.
The UK business is headed up by Malcolm Reynolds, who was formerly UK head of pension administration at Mercer.
Aptia said the combination of what it said is the largest pensions administrator in the UK and one of the most trusted health and benefits administration platforms in the US enabled the firm to launch as a business with "significant scale, resources, deep technical expertise, proven solutions, and key insurer relationships".
Commenting on the firm's formal launch, Viswanathan said: "In a highly complex and underserved market, we are excited to launch a global specialist business that has a team with an unrelenting focus on client service and technological advancement.
"Aptia is committed to raising standards and providing our clients with fresh perspectives and insights. Our solutions, which are delivered by teams trusted by some of the world's largest employers, will deliver real value to clients and their employees, members, and policyholders."
Burke added: "Because we are launching with an experienced team and established platforms, we have a unique ability to help clients navigate the complexities inherent in delivering efficient pensions and benefit administration.
"At the heart of Aptia's strategy is a deep commitment to investing in our greatest assets - our people and our technology. By doing so, we position ourselves for the future, ensuring our ability to deliver forward-thinking and reliable solutions."
