Most frontline teams still rely on outdated radios and fragmented communication tools. The result: delays, miscommunication, and operational risk. PTTHEX replaces this with a secure, real-time communication infrastructure built for modern field operations. We transform smartphones into mission-critical push-to-talk systems enabling teams to communicate instantly, securely, and across any environment. With PTTHEX, organizations can: • Coordinate teams in real time through encrypted voice and messaging • Operate across 4G/5G, Wi-Fi, and offline environments • Enable multilingual communication for global teams • Improve safety with SOS alerts, emergency detection, and event logging • Replace hardware-based radios with a scalable, software-driven platform Unlike traditional walkie-talkies or consumer apps, PTTHEX combines enterprise-grade security, hybrid connectivity, and AI-powered capabilities to ensure communication never becomes a bottleneck. Proven Early Demand PTTHEX is validated through multiple signed LOIs and pilot engagements across Europe and the Middle East. Early partners plan deployments of 15–30 users per team, with strong expansion potential. Feedback highlights faster coordination, reduced communication gaps, and clear demand to replace legacy radio systems. Strategic Position PTTHEX is not just a tool.
