CallTower, a global leader in cloud-based communications solutions, has announced a strategic investment by Court Square Capital Partners. This partnership marks a significant milestone that will enable the company to accelerate its growth trajectory and expand its global footprint.
CallTower operates at the forefront of managed service providers delivering cloud communications in complex, multi-vendor, multi-location environments. The company provides seamless integration of industry-leading platforms tailored for mid-sized and enterprise customers.
This new investment from Court Square will help CallTower expand its distribution channels, enhance proprietary technology, and bring modern communications platforms to more enterprise organizations worldwide. It follows a successful period under BV Investment Partners, during which CallTower broadened its solution set through the acquisition of Inoria and strengthened vendor partnerships.
Bret England, President & Chief Executive Officer of CallTower, said, “This transformative investment signals an exciting new chapter for CallTower and its customers, employees, and technology partners. With Court Square's deep expertise and substantial resources, CallTower is well-positioned to expand its distribution channels, enhance its proprietary technology, and bring modern communications platforms to more enterprise organizations on a global basis. As the communications landscape continues to evolve, this partnership with Court Square solidifies CallTower’s leadership in advanced Managed UC and CX Communications with exceptional Professional Services and extraordinary customer experience. CallTower’s experience with BV has been excellent and we look forward to continuing our impressive results with Court Square.”
As businesses adapt to hybrid and distributed workforces, demand for best-of-breed managed communication platforms continues to grow. Court Square recognized CallTower’s position as a solution-agnostic provider that delivers exceptional value to customers.
“CallTower has set the standard for global cloud-based communications, excelling in complex, multi-vendor, and multi-location environments,” said Christopher Bloise, President and Managing Partner at Court Square Capital Partners. “We look forward to building on this strong foundation by supporting CallTower’s continued growth and innovation in the managed communications space.”
Together, CallTower and Court Square plan to capitalize on the shift from legacy telephony and contact center systems through both organic and inorganic growth strategies.
Bret England noted, “This transaction is a testament to the value CallTower has created over the years, and Q Advisors was a critical part of that story. From before our original partnership with BV Investment Partners to this milestone investment by Court Square, Q Advisors brought unmatched knowledge of the managed communications landscape and an exceptional ability to position CallTower's differentiated platform and articulate our growth opportunity. CallTower is grateful to have had Q Advisors join us in our journey.”
