Vieaux is currently president and chief operating officer of Finlocker, where he has been with the company since July 2019. Previous roles in the lending side of the business include stints at Flagstar Bank, Towne Mortgage, IndyMac Bank, CitiMortgage and Source One Mortgage.

MISMO is an affiliate of the Mortgage Bankers Association and leadership of the group will put Vieaux in a position central to the coordination of industry data standards.

MBA President and CEO Bob Broeksmit said in a press release that Vieaux's executive roles in the industry and a demonstrated ability to forge consensus within it made him a good fit for the leadership position at the standards organization.

"I am confident his passion for the industry and fresh ideas will drive innovation, increase stakeholder participation, and continue to advance MISMO industry standards that benefit consumers, lenders, and servicers," Broeksmit said.

Richard Hill has been acting president of MISMO since September 2024 when David Coleman left the organization. Coleman succeeded Seth Appleton in March 2023.

Appleton left the role in January 2023 to head up the U.S. Mortgage Insurers.

"MISMO plays a critical role in supporting the entire mortgage ecosystem, and we look forward to collaborating with Brian as he guides MISMO into its next chapter of growth," the organization's chair, Sage Nichols, said.

As a result of Vieaux' departure Finlocker will be promoting Chris Hazen to chief revenue officer and Ethan Vieaux to vice president, customer success, the company said in a LinkedIn posting.

Last week, MISMO published the previously announced update to its Consumer-Facing Charge and Fee Naming Guide.

The guide adds 40 new fees to MISMO standards and "enables lenders to effectively support evolving loan origination practices, particularly in the expanding e-mortgage sector" Hill said in a press release.
