Aspen HR, a leading provider of comprehensive PEO solutions, payroll, benefits, and HR compliance, is celebrating its 3rd year in a row on the annual Inc. 5000 list, the most prestigious ranking of the fastest-growing private companies in America.

Aspen HR was recognized for achieving an impressive 419% 3-year growth. The company’s continued success has been driven by expanding its client base across the United States and the increasing need for PEO services in their industries of focus: alternative assets, financial services, fintech, software, tech-enabled services, and professional services.
“We are honored to be selected for the Inc. 5000 list, which reflects our commitment to delivering white-glove service and value to our clients,” said Mark Sinatra, CEO at Aspen HR. “We’ve developed a solution that empowers our clients to focus on their core business and growth while we handle their HR needs and challenges. I’m proud of our team and excited about the future as we transform the HR and PEO industry.”

“We started Aspen HR with a passion for revolutionizing the client service experience in the HR and PEO industry, and we are so proud of how far we’ve come. Thank you to the team, our trusted partners, and clients who have supported us on this journey,” said Jenny Souksavath, COO/Co-Founder at Aspen HR.

Aspen HR enables companies to outperform through a full range of HR solutions including payroll and tax processing, expert HR support, Fortune 500 caliber benefit plans and administration, cloud HR software, robust integrated 401 (k), and their white-glove experience.

The market for PEO services has surged in recent years. Experts predict it will surpass $160 billion by 2031. PEOs can help businesses outsource important HR functions while ensuring compliance with federal and state employment laws. By working with a PEO, businesses can save time and money, improve employee benefits and retention, and reduce risks and liabilities.
