Vestmark has entered into a strategic partnership with Corient to provide portfolio management and trading technology across the RIA’s full advisor network.
Under the agreement announced Wednesday, Corient will use Vestmark’s platform to consolidate portfolio management functions and unify trading operations for its entire book of approximately $177 billion in client assets.
The move reflects an effort by the Miami-based firm to streamline its investment infrastructure as it expands nationally.
“With Vestmark, we have selected a partner that will enable trading at the scale of a leading national wealth manager, such as Corient,” Lennie Gullan, partner and chief operating officer at Corient, said in a statement announcing the relationship.
The technology rollout comes amid a wave of structural changes and acquisitions for Corient, a fee-only fiduciary wealth firm and US subsidiary of Toronto-based CI Financial.
In November, CI Financial revealed that it had agreed to be acquired by Mubadala Capital, the asset management arm of Abu Dhabi’s sovereign wealth fund. The all-cash deal, valued at C$12.1 billion, is expected to close in mid-2025. The privatization is anticipated to provide CI’s US wealth business, including Corient, with greater flexibility and capital resources to pursue expansion.
The months following the announcement saw a series of acquisition announcements aimed at deepening Corient's footprint and capabilities.
In December, the firm revealed a plan to acquire H.M. Payson & Co., the largest RIA in Maine with $7.9 billion in assets. That transaction marked Corient’s entry into the state’s wealth market.
The following month, Corient completed its acquisition of Geller & Company’s multi-family office business. That deal added $10.4 billion in assets and bolstered Corient’s reach in New York City, particularly in serving ultra-high-net-worth households.
In February, the firm expanded again as it snapped up Pittsburgh-based Rootstock Advisors, a family office-focused RIA managing approximately $600 million.
Corient also recently made a couple of stealthy leadership changes in March when it promoted Darren Henderson to head of US wealth advisory and Alex Eppler to head of client operations, according to a regulatory filing with the Securities and Exchange Commission.
The partnership with Vestmark is seen as a foundational element in aligning Corient’s investment capabilities across its growing platform. Vestmark’s system is designed to support enterprise-level asset and trading workflows, enabling advisors to access centralized tools and streamlined processes.
“We are extremely pleased to have been chosen as one of Corient’s key strategic partners. Our goal is to provide them with a robust and consistent technology foundation to power their continued growth,” said Karl Roessner, chief executive of Vestmark.
Vestmark’s platform currently supports $1.5 trillion in assets across more than 5.5 million accounts and is used by six of the 10 largest managed account platforms in the industry. More than 65,000 advisors utilize its technology, which includes a model marketplace offering over 1,200 investment strategies.
