Recruitment software providers Jobvite and JazzHR along with NXTThing RPO are being acquired by K1 Investment Management, a private equity firm based in Manhattan Beach, California. The three firms will be combined into a single business with Peter Lamson, CEO of JazzHR, serving as CEO for the combined company.

The transactions closed earlier this month; terms of the deals were not announced.

“Through our combined businesses, we are unparalleled in markets we cover, with purpose-built and data-driven solutions ranging from SMB to enterprise,” Lamson said. “We are the only talent acquisition provider to offer discrete SMB and enterprise grade technology solutions, and couple both with industry-leading recruitment services.”

All three firms will continue to operate under their respective brands.

JazzHR is a provider of recruitment software, including applicant tracking and other services, based in Pittsburgh. It operates with a focus on small and midsize companies.

NXTThing RPO provides recruitment process outsourcing services and is based in Jacksonville, Florida.

Jobvite provides an applicant tracking system and recruiting software and is based in Indianapolis. The company announced a move to that city earlier this year from San Mateo, California.

In a video, Lamson said one aspect of the deal is that companies expanding to the point where they need an enterprise-level ATS will be able to transfer seamlessly to Jobvite’s platform.

Jobvite CEO Aman Brar will join the board of the combined company.

Combined, the company serves more than 10,000 employers and attract 11 million job seekers per month.
