Not many staffing firms make it three decades, let alone reinvent themselves along the way. But Atrium, founded in New York in 1995, is marking its 30th anniversary by reflecting on its transformation from a boutique staffing agency into a global leader in extended workforce management and talent solutions.
Back in the mid-’90s, founder and CEO Rebecca Cenni-Leventhal built Atrium on a simple but unconventional belief: the employee experience should extend to every worker—not just full-timers. That candidate-first mindset helped the company stand out in a crowded staffing market and paved the way for its Applicant-Centric™ culture.
Fast forward to 2025, Atrium now operates 20 locations worldwide, employs about 250 internal staff, manages a community of 20,000+ contractors, and supports 1,000+ programs across the U.S.
“I’m incredibly grateful as I reflect on the growth and impact Atrium has achieved over the years,” said Cenni-Leventhal. “From day one, our mission has been to connect top talent to amazing opportunities while creating strong, lasting partnerships.”
From Staffing Boutique to Global Workforce Partner
Over three decades, Atrium has repeatedly evolved its offerings to keep pace with workforce shifts. Key milestones include:
-
2003: Achieved WBENC certification, boosting representation for women-owned businesses and mentoring newcomers in the industry.
-
2008: Launched AtriumWORKS, now a recognized market leader in enterprise contingent program management, offering MSP, EOR/AOR, direct sourcing, and compliance solutions.
-
2015: Introduced Engagent™, proprietary tech for vetting 1099 contractors and reducing compliance risks.
-
2023: Expanded globally into the EMEA region, extending its footprint for multinational clients and tapping growth markets.
Why It Matters
The contingent workforce is no longer peripheral—it’s central. According to Deloitte, nearly 40% of the U.S. workforce is now non-traditional (freelancers, contractors, gig workers). Companies are increasingly seeking partners who can balance compliance risk, global scalability, and talent access while still delivering a personalized experience.
Atrium’s trajectory shows how staffing firms must evolve into tech-enabled workforce management partners to stay competitive. Rivals like Allegis Global Solutions and Randstad Sourceright have also leaned into digital transformation, but Atrium’s proprietary compliance platform and people-first narrative differentiate its playbook.
The Road Ahead
As workforce models continue shifting, Atrium says it’s committed to blending human connection with technology-driven solutions. The company plans to deepen its focus on contingent talent strategies while expanding global capabilities.
“As we look to the future, we’re proud of the relationships we’ve built and remain focused on creating value for clients, candidates, and communities,” Cenni-Leventhal added.
Thirty years in, Atrium is betting that staying human at the core of workforce management is the way to thrive in the next 30.
