1 verified life saved, plus many less serious incidents resolved fast

For more than 20 years I've sold technology that locates and protects people: nurse-call and duress systems in hospitals, child tracking in theme parks, and staff-safety panic buttons in hotels. I've built two companies, opened a new country from zero, and won against much larger competitors in 10 countries.
