Cornerstone Capital Group, an RIA based in New York City and Denver that was created three years ago, is closing in on the $1 billion mark in assets under management, the firm announced Thursday.

Cornerstone focuses on investments that take environmental, social and governance issues into account. Erika Karp, Cornerstone founder and CEO, said the increasing interest in sustainable and ESG investing on the part of the public, is partially responsible for the firm’s rapid growth.

Cornerstone is one of the fastest organically growing RIAs in the country, according to Karp. It serves individuals, family offices, endowments and foundations, as well as providing corporate advisory services to organizations that want to engage shareholders in sustainability initiatives.

“ESG is an investing discipline that is being more broadly accepted,” said Karp. “The myth that sustainable investing underperforms the rest of the market is being put to bed. We see this discipline as a growth opportunity. We would like to double our AUM every year.
“There are those who are still doing their grandfather’s version of sustainable investing by just screening out some products,” she said. “But true ESG investing is complex and considers” everything thing from the supply chain, to where women are in all aspects of the company, to climate change.

“Sustainable investing is just investing, but in a more humane way,” Karp said.
