CallTower has completed the acquisition of assets associated with Momentum Telecom’s cloud voice and collaboration business, including its customer relationships. The transaction brings more than 3,500 Momentum customers and more than 250 employees to CallTower, expanding its customer base to more than 8,500 organizations.
The transaction substantially increases CallTower’s scale across managed communications services in the UC and CX technology stack, said the company, enabling CallTower to reinvest in new products, technology, talent, and customer capabilities while pursuing additional organic growth and strategic acquisitions.
Along with the more than 250 Momentum employees,CallTower’s executive leadership team will also be expanded through the addition of four senior leaders from Momentum: Mark Marquez, Chief Technology Officer; Jennifer Jacobs, Chief Operating Officer; Heather Levenberg, Senior Vice President of Human Resources; and Joe Coomes, Senior Vice President and General Counsel.
“This acquisition marks a defining moment in CallTower’s growth,” said Bret England, President and Chief Executive Officer of CallTower. “With expanded voice expertise, a broader portfolio of communications products, and greater technical and operational capacity, CallTower is better positioned to help enterprises modernize legacy communications, navigate complex UC, CX, and AI technology environments, and deliver connected experiences for employees and customers worldwide.”
Momentum will continue operating independently after the transaction, keeping its global network connectivity and managed services businesses under the Momentum name. The companies said they are working closely to maintain business continuity and support a smooth transition for employees, customers, and partners.
“[The transaction] allows us to focus fully on global network connectivity and on building the secure, resilient infrastructure businesses need to be AI-ready,” added Todd Zittrouer, CEO of Momentum “We look forward to working alongside our partners and customers to help them connect, protect, and prepare their networks for what comes next.”
Q Advisors served as exclusive financial adviser to Momentum, and Dechert LLP served as legal counsel.
