SirenGPS is a St. Louis startup that created emergency management software to help first responders find people faster when they call 911 and share information with emergency managers. The software provides tools for emergency communications. The technology is intended for communities, schools, hospitals, corporations and major events like Fair St. Louis. St. Louis tested the software at Fair St. Louis, the city’s July 4th celebration in Forest Park. For individuals signed up to use the free app, the caller’s location, personal and medical information is shared immediately with first responders before they arrive on scene.
