Singapore-based ultra high net-worth (UHNW) research firm Wealth-X is buying London, UK-based Ledbury Research to bolster its position in the wealth research niche.

Ledbury, which was founded in 2003, specializes in market research on wealthy consumers and their advisors. It conducts interviews with tens of thousands of global high net worth individuals each year as well as recruiters and other experts.

Following the acquisition, Wealth-X will employ more than 250 people in 13 cities worldwide. Ledbury Research will take on Wealth-X branding, and its co-founder, Marc Cohen, will remain with the firm, reporting to Wealth-X CEO Mykolas Rambus.

“We are extremely excited to join Wealth-X and align ourselves with the company that has defined the ultra-affluent category. Our clients will only benefit from their wealth big data capabilities, best practices, and global reach,” said Cohen.

Rambus says that the acquisition demonstrates its commitment to expanding in Europe, the Middle East and Africa.
