History of UKG
- Founded: 2020
- Founders: Hellman & Friedman (merger sponsor)
The constituent companies each had storied pasts. Ultimate Software was founded in 1990 by Scott Scherr in Weston, Florida, went public in 1998, and was taken private by H&F in 2019. Kronos was founded in 1977 by Mark Ain in Massachusetts, built the first microprocessor-based time clock, and was itself taken private in 2007.
The merger logic was complementary strength: Ultimate dominated human capital management and payroll for large enterprises, while Kronos owned workforce management, time clocks, and scheduling for hourly workforces. Together they could sell a single platform covering every employee from boardroom to factory floor.
The combined company launched in April 2020 just as COVID-19 hit, forcing it to integrate two businesses while demand for remote workforce tools spiked. It immediately became one of the largest private software companies, with revenue above $3 billion.
Since the merger UKG has consolidated under a single platform strategy, merging the two product lines and pushing AI-assisted workforce features. It remains a sponsor-owned company with roughly 16,000 employees and approximately $3.7 billion in annual revenue, managed toward an eventual public or private exit.

Awards & Recognition
UKG has appeared on Fortune's Best Companies to Work For and Forbes' America's Best Employers lists repeatedly since the merger. Its predecessor companies had similar records, with Ultimate named one of the best places to work for 15 consecutive years. The company is also a consistent Gartner leader in human capital management and workforce management categories.
UKG Recalls & Controversies
UKG's most significant incident was the December 2021 ransomware attack on its private cloud, which took its Kronos Private Cloud service offline for weeks and disrupted payroll and scheduling for major employers including Tesla, PepsiCo, and the City of New York. The outage produced lawsuits, customer compensation demands, and lasting scrutiny of its cloud resilience.

The company has also faced criticism for integration missteps following the merger, including reported customer service degradation and billing disputes, and for periodic layoffs as it consolidates the combined organization. It has settled wage and hour class actions related to its own workforce over the years.
