Atlas UP
Semaphore Mobile partnered with Atlas UP to architect and build the mobile experience for their AI-powered Chief of Staff platform — a product trusted by the U.S. Department of Defense.
Atlas UP needed a mobile engineering team that could match the rigor of their military-grade security standards while delivering a fluid, consumer-grade user experience. We designed and developed their cross-platform mobile app from the ground up — implementing secure real-time messaging, intelligent task delegation flows, and seamless integration with their AI orchestration engine. The result: enterprise teams now manage people, goals, and resources from anywhere, 24/7.
