From Battalion Chief to CBO: A Veteran First Responder Takes the Helm of Diga-Talk’s Growth

JOLIET, IL – March 02, 2026 – Diga-Talk Solutions, a key player in nationwide mission-critical communications, has appointed John K. Sullivan as its new Chief Business Officer. The move signals a strategic deepening of the company's commitment to sectors where communication is not just a convenience, but a lifeline. Sullivan brings a rare and potent combination of experience to the C-suite: nearly three decades in communication sales running parallel to a distinguished 30-year career in the fire service, from which he retired as a Battalion Chief.

This promotion, coming shortly after Sullivan joined the company full-time in December 2025, is more than a standard executive shuffle. It places a leader with firsthand, high-stakes operational knowledge at the forefront of business strategy, a decision that underscores the company’s focus on authenticity and expertise in the public safety, education, and enterprise markets it serves.

A Career Forged in Service and Sales

Understanding John K. Sullivan’s value to Diga-Talk Solutions requires looking at two parallel tracks of a remarkable career. For 30 years, he served the Addison Fire Protection District, rising through the ranks to Battalion Chief. This role immersed him daily in the realities of emergency response, where coordinated, reliable communication is the bedrock of operational success and public safety. He experienced firsthand the consequences of communication failures and the critical need for tools that perform flawlessly under pressure.

Simultaneously, Sullivan was building a nearly 30-year career in sales at A Beep, LLC, the company that would eventually evolve into Diga-Talk Solutions. This dual life provided him with a unique perspective, allowing him to bridge the gap between the engineers designing communication technology and the end-users relying on it in life-or-death situations. He wasn’t just selling a product; he was offering solutions to problems he intimately understood from his own experience on the front lines.

His promotion to CBO is the culmination of this dual expertise. In his new role, Sullivan will guide strategic growth, business development, and operational alignment across all of Diga-Talk's brands. His credibility within the public safety community is a significant asset, providing an immediate level of trust and understanding when engaging with fire departments, police agencies, and other first responders.

Steering a 30-Year Legacy into the Future

Sullivan’s appointment is a pivotal moment for Diga-Talk Solutions, especially as the company prepares to celebrate its 30th anniversary in 2026. Founded in 1996 as A Beep, LLC, the firm established itself as a reliable provider of digital two-way communications. Recognizing the industry's shift, the company launched its Diga-Talk Plus brand in 2017 to pioneer advanced Push-to-Talk over Cellular (PoC) solutions. The recent rebranding to Diga-Talk Solutions consolidates this forward-looking vision.

This evolution reflects the broader transformation in the critical communications industry. The global PoC market, valued at over $7.5 billion in 2025, is projected to more than double to nearly $17 billion by 2034. This explosive growth is driven by the demand for more flexible, feature-rich, and cost-effective alternatives to traditional Land Mobile Radio (LMR) systems.

As CBO, Sullivan is tasked with navigating this dynamic landscape, ensuring the company not only participates in the market’s growth but leads it. His deep industry roots, dating back to the company's origins, provide a stable foundation, while his operational background ensures that innovation remains grounded in the practical needs of customers.

The PoC Revolution in Critical Sectors

The technology at the heart of Diga-Talk's strategy is Push-to-Talk over Cellular. PoC leverages the vast infrastructure of 4G LTE and emerging 5G networks to provide instant, walkie-talkie-style communication with nationwide coverage. This overcomes the significant range limitations and high infrastructure costs associated with traditional radio systems.

For sectors like public safety, transportation, and education, the benefits are transformative. Diga-Talk+ devices offer features like GPS tracking, emergency alert buttons, and interoperability with smartphones, all while providing the rugged durability required for field use. The company’s focus on this technology is particularly timely, as North America currently dominates the global PoC market, with public safety and security being the largest and fastest-growing segments.

Diga-Talk has strategically positioned its offerings to meet the stringent requirements of these fields. Several of its devices are FirstNet Ready™, certified for use on the dedicated nationwide broadband network built for first responders. This provides public safety agencies—and extended primary users like school districts and utility companies—with priority access to communication channels, even when commercial networks are congested during major emergencies. The company's School-Radio brand further targets the specific needs of educational institutions, a market Sullivan understands well from his public safety background.

Bridging Gaps with Next-Generation Technology

Under Sullivan’s strategic guidance, Diga-Talk Solutions is pushing beyond standard PoC offerings by integrating cutting-edge technologies to solve persistent communication challenges. A key initiative is the planned integration of Low Earth Orbit (LEO) satellite connectivity. This will address one of the primary weaknesses of cellular-based systems: coverage gaps in rural and remote areas. By providing a satellite-based backup, Diga-Talk aims to deliver truly seamless communication, ensuring that teams remain connected whether they are in a dense urban center or a remote wilderness.

The company is also leveraging software and AI to enhance its services. A comprehensive PC Dispatch Software suite allows managers to monitor their mobile workforce in real-time, track assets via GPS, manage group calls, and receive SOS notifications. Furthermore, the integration of AI-powered voice analytics offers new possibilities for improving operational efficiency and safety.

The practical impact of this technology is already being felt. In Crystal Lake, Illinois, School Districts 47 and 155 equipped their fleet of 146 buses with Diga-Talk+ units. The assistant director of transportation noted the system’s reliability and clear communication, which are vital for coordinating student transport safely and efficiently. This real-world success in a critical sector exemplifies the market Diga-Talk is built to serve. With John K. Sullivan helping to chart the course, the company is poised to deepen its impact, leveraging three decades of history and a lifetime of operational experience to define the future of critical communications.
