BOSTON, November 16, 2023 – BV Investment Partners (BV), a middle-market private equity firm focused on the tech-enabled business services, software and IT services sectors, announced today an investment in CallTower, an international leader in delivering cloud-based enterprise-class communications, contact center and collaboration solutions.

CallTower is based in South Jordan, UT and serves over a million end points covering over 75 countries.

As a solution-agnostic provider aligned with best-of-breed platforms, CallTower is helping change the way people communicate around the world and get work done.  We have found a like-minded partner in BV and this new relationship will help us to accelerate our growth, both organically and through acquisitions, while maintaining a healthy, well-functioning organization and providing exceptional service to our customers.”

Justin Garrison, Managing Director of BV, said, “Enterprises and their employees have made a lasting shift in how they communicate centered around modern collaboration platforms. CallTower stands to benefit from the long-term trends of cloud migration, growth in hybrid and distributed workforces, and migration towards best-of-breed platforms.  Bret and the CallTower team have built an exceptional organization and we’re excited to partner with them to support and enable an ambitious growth strategy.”

Vik Raina, CEO and Managing Partner of BV, added, “Cloud communications is a $15+ billion market which is expected to grow double digits as enterprises continue to adopt collaboration platforms and switch away from legacy systems.
