the 33-person management committee. Goldman also said it had formed a committee to promote the careers of diverse business leaders at the company.

Changing course

As trading becomes a less reliable source of income, and many competitors scale up, Solomon's Goldman is expected to explore new ways to grow its business.

"The supermarket finance business model is what's working well today, and Goldman is a lot [narrower]," Biggar said.

Some of this work is underway. Last year, Goldman released a plan to boost revenue by $5 billion by 2020, in part by bulking up other parts of the company.

And the firm has doubled down on its consumer arm, Marcus. Goldman, which launched Marcus in the United States in 2016, started to offer savings accounts in the UK last week. The bank mayexpand into life insurance, mortgages, auto loans and wealth management services down the road.

"We have the ambition to build a large, differentiated, highly profitable digital consumer finance platform," Solomon said in May.

Solomon has been at the bank since 1999. He's expected to be a leader in Blankfein's mold, though his extracurricular interests certainly set him apart.

"This is not somebody they're bringing in from the outside that will radically alter the makeup of the company," Biggar said. "I don't think anyone's expecting that. But there are things on the edges he could do."
