Arcesium, a global financial technology provider to the investment industry, today announced the appointment of Brian Rosenberg as president, revenue and commercial. Rosenberg will join Arcesium’s executive committee and oversee all aspects of client and partner development, as well as go-to-market strategy and execution. Rosenberg brings two decades of experience leading global commercial teams at institutions including Wilshire Indexes, Qontigo, FTSE Russell, LSEG, SunGard, MSCI and RiskMetrics Group.
Rosenberg joins the company as it continues expanding its global client base following its acquisition of front-office platform, Limina, and the launch of its investment-native AI platform, Arcesium Intelligence. He will help shape Arcesium’s competitive positioning and product roadmap with a focus on helping buy-side and sell-side firms operationalize agentic AI.
“Brian is a natural and exciting addition to Arcesium. He has an impressive record of aligning product-commercial strategy and translating complex capabilities into durable client value,” Gaurav Suri, CEO of Arcesium, said. “We have built significant momentum by staying focused on solving complex challenges for our clients. With Brian’s experience in driving revenue, I’m confident we can extend that momentum, broaden our impact, and bring our capabilities to more firms across the industry.”
Most recently, Rosenberg led commercial strategy, revenue operations, strategic partnerships and go-to-market execution as president and chief revenue officer of Wilshire Indexes. Before that, he served as chief revenue officer at Qontigo, part of Deutsche Börse Group, where he guided the integration of market indices STOXX and DAX with Axioma’s investment technology. Previously, at LSEG, Rosenberg served as managing director, global head of sales and co-head of North America, helping to lead the overall strategy and growth of the Information Services business. His broad commercial remit spanned global sales and strategic initiatives, including the integration of FTSE and Russell.
“I am excited to join a market-leading investment technology provider so well-positioned for growth,” Rosenberg said. “Arcesium has a proven reputation as a partner in transforming data and operations for investment firms. I see a significant opportunity to build on that foundation, enabling more institutions to modernize their infrastructure, operate across asset classes, and derive greater value from AI.”
Market complexity continues to accelerate, and Arcesium’s platform — anchored by Opterra and Aquata and increasingly powered by AI — is already helping investment firms operate ahead of it. As revenue and commercial lead, Rosenberg will help bring these capabilities to new clients, scaling their impact across asset classes.
