Aaron Klein Joins Tech Consultancy Ezra Group as 'Executive in Residence'

Klein recently also joined wealthtech startup Fynancial as a strategic advisor.

Aaron Klein, founder and former longtime CEO of Nitrogen—formerly Riskalyze—has joined the advisor technology consultancy Ezra Group as an executive in residence.

Klein, who stepped down as Nitrogen’s CEO in late 2023, remains on the company’s board of directors and also sits on the boards of Snappy Kraken and the Mountain States Policy Center.

He also joined wealthtech startup Fynancial in January as a strategic advisor. Fynancial is building what the company refers to as a "Social Financial Platform" for the wealth management industry.

Dan Zitting, a B2B entrepreneur, succeeded Klein as CEO of Nitrogen in December

While the salary for the Ezra Group position was not disclosed, Klein will use his years of experience developing the Riskalyze and Nitrogen business lines, integration efforts and industry knowledge “to provide strategic guidance, thought leadership and mentorship to the firm’s team of consultants and clients,” according to a prepared statement.

Klein was named CEO of the Year at the 2023 Industry Awards, among other industry accolades over his career.

Nitrogen has grown over the years from a risk metrics and profiling tool and expanded into many other areas including trading, rebalancing and marketing automation and later tax-loss harvesting and home office management tools, among other offerings.

It was just a little over 11 years ago that Klein rolled out Riskalyze’s first paid Pro product for financial advisors in 2012. He launched the company in 2011, providing a free risk measurement and analysis tool for investors.
