Spectrotel and AireSpring Announce Closing of Merger, Bringing Together Scale, Intelligence, and Network Control

The combined company creates a differentiated managed network services platform built to meet the evolving demands of distributed and global enterprises

NEPTUNE, N.J. — September 30, 2026 — Spectrotel Holding, LLC (“Spectrotel” or the “Company”), a provider of managed network services and connectivity solutions, today announced the completion of its previously announced merger with AireSpring, a provider of global connectivity, managed services and network infrastructure solutions. The transaction brings together two channel-focused companies with complementary capabilities across managed networking, connectivity and communications.

Spectrotel’s experience supporting complex, distributed enterprises is now paired with AireSpring’s nationwide facilities-based fiber network, geo-redundant voice infrastructure and global connectivity capabilities. Together, these complementary strengths establish a broader operating platform spanning enterprise, mid-market and SMB customers, including organizations with multi-location and global requirements.

Backed by Charlesbank Capital Partners, the newly merged organization also benefits from continued investment by Grain Management, while members of the Lonstein family, AireSpring’s founders, remain significant minority investors.

“The market is moving beyond buying connectivity and individual technology solutions toward something much more strategic — enterprises want a partner that can take accountability for how their network performs and the outcomes it delivers,” said Ross Artale, Chief Executive Officer of Spectrotel. “Merging Spectrotel and AireSpring gives us the scale, network control, global reach and expertise to meet that expectation. This combination accelerates our ability to anticipate issues earlier, reduce complexity for customers and define what the next generation of managed network services should deliver for customers and our channel partners.”

"Spectrotel and AireSpring have each earned the trust of enterprises and channel partners by delivering reliable network performance at scale,” said Mike McGuire, Managing Director at Charlesbank. “Our investment reflects years of thematic work in this market and conviction in the growing demand for managed network services. Together, we believe these two companies have the technology, talent and scale to deliver even more for customers, and we look forward to partnering with Ross, the management team and Grain to accelerate that work.”

With the merger closed, Spectrotel and AireSpring will move forward as a single organization – integrating networks, teams and infrastructure to deliver on a single platform. Customer and partner relationships remain central to that effort, with a focus on maintaining service continuity while expanding access to the combined organization’s portfolio, expertise and network capabilities.

Leadership and Organization

The company has established an executive leadership team designed to unite the experience, capabilities and perspectives of both organizations and lead its next phase of growth. Ross Artale will continue as Chief Executive Officer, with Russ Shipley, formerly Chief Operating Officer of AireSpring, serving as Chief Operating Officer. Terri Vaccarino, currently Senior Vice President of Product & Marketing at Spectrotel, will become Chief Marketing Officer. Adam Siskind will continue as Chief Financial Officer, Sanjay Patel as Chief Technology Officer and Gabe Sette as Chief Revenue Officer. Together, the leadership team will be responsible for bringing the strengths of Spectrotel and AireSpring together and executing the company’s strategy as one organization.
