Ain and other executives at UKG, as the company is now called, are currently dealing with the aftermath of a Kronos Private Cloud cyberattack. The ransomware attack has taken the company’s private cloud offline, potentially for weeks, and this is expected to impact HR and paychecks for employees of companies that use Kronos for timekeeping.

Aron Ain is the CEO of UKG

Aron Ain, who began working at Kronos Inc. in the late 1970s, moved up the ranks over the years with several executive vice-president roles. In 2005, he became CEO of Kronos, a role for which he has won several business awards.

UKG's company management solutions include HR and timekeeping services.

In 2007, Ain was instrumental in negotiating the $1.8 billion sale of Kronos to Hellman & Friedman, which took the company off the Nasdaq to become private again. In 2012, Ain received the Ernst & Young Entrepreneur of the Year Award for New England. Glassdoor also ranked Ain at number 18 on its “Highest-rated CEO” listing in 2016.

Aron Ain's net worth and salary

Although Ain’s salary as the top Kronos executive and now the top UKG executive are not publicly known, he's likely well compensated for the position of influence he holds in the company.

In 2014, the company surpassed $1 billion in revenue. As of 2018, Kronos had over 35,000 customers globally, and in 2020, the combined value of the company post-merger was $22 billion, so Ain’s salary and net worth are likely commensurate with the company’s success.
