No reputable outlet has published a net worth figure for Aron Ain. He spent more than four decades at Kronos, the workforce software company his brother founded. He was its CEO from 2005 and then led UKG, the company formed when Kronos merged with Ultimate Software in 2020. He stepped down as UKG's CEO in 2022 and became executive chair. The $58 million figure this page used to show had no source and has been removed.
What is Aron Ain's net worth?
There is no reliable estimate. Kronos stopped publishing executive pay in proxy filings when it was taken private in 2007, and UKG is owned by private equity investors. It does not disclose how much stock its executives hold. No Forbes, Bloomberg or Boston Business Journal report gives a figure for Ain's personal wealth.
What is known is the size of the companies he ran. WBZ NewsRadio reported in 2021 that Kronos revenue more than tripled to over $1.5 billion during his time as CEO, and that UKG started with more than 13,000 employees and about $3 billion in revenue. A long-serving CEO of a company that size usually receives equity worth a great deal, but how much Ain holds has never been reported.
Aron Ain's yearly income and salary
His salary has not been published since Kronos went private. The old version of this page claimed $2.25 million a year with a monthly and daily breakdown, but it gave no source, so the figures have been removed. As executive chair of a private company, his current pay is not public.

Career at Kronos and UKG
In a 2025 interview with Adam Mendler, Ain said his brother Mark founded Kronos in 1977. He joined two years later, straight out of college, and did everything from chasing sales leads to cleaning. He then worked his way through almost every part of the business. According to Wikipedia, the company went public in 1992.

Adam Mendler's January 2025 interview still called him UKG's executive chair.
Leadership approach and WorkInspired
Ain is best known for arguing that engaged employees lead to better business results. His 2018 book, WorkInspired: How to Build an Organization Where Everyone Loves to Work, explains how Kronos used employee engagement as a strategy. It covers the open vacation policy and a Manager Effectiveness Index that let employees rate their managers. Harvard Business Review, Fortune and The Wall Street Journal all wrote about these policies. WBZ says he was named to Glassdoor's list of top CEOs in several years.
Awards and board roles
According to Wikipedia, Ain has received the Ernst & Young Entrepreneur of the Year award, the Massachusetts High Technology Council's Ray Stata Leadership and Innovation Award, and the Massachusetts Technology Leadership Council's CEO of the Year award. He is a trustee of Hamilton College, his alma mater, and of Beth Israel Deaconess Medical Center in Boston. He also sits on the board of Combined Jewish Philanthropies of Greater Boston. In the Mendler interview he said volunteering and philanthropy take up a lot of his time.
Early life and education
Ain graduated from Hamilton College, which Wikipedia confirms. The old page said he studied economics and government there and attended the AEA/Stanford Executive Institute. We could not confirm those details from a source we opened, so this page lists only the degree. The old page's claims about his childhood had no source and have been removed.
Aron Ain's wife
Ain keeps his family life private, and the sources we reviewed do not name his spouse. The old page's paragraph about his marriage contained no facts and has been removed.
Age, height and weight
His birth date is not published. He graduated from college in 1979, which suggests he was born around 1957, but that is an inference, not a reported fact. The height of 5 feet 4 inches and weight of 99 kg on the old page had no source and have been removed.

Why no figure is given
Executives at private-equity-owned companies usually hold equity whose value only becomes known when there is a sale or an IPO. UKG has done neither since the merger, so any number for Ain would be a guess. What can be said is that he spent 43 years at one company, ran it for 17 of them, and saw it grow from his brother's startup into a software business with billions in yearly revenue.
