The document proposes FirstSix, a platform that crowdsources emergency medical services by leveraging trained medical professionals nearby when someone calls 911. It aims to improve low survival rates from cardiac arrest by providing faster response times than traditional ambulances. FirstSix's mobile app would allow 911 operators to see and dispatch the nearest certified responders to deliver initial care while awaiting paramedics, potentially saving more lives threatened by traffic or other response delays. The founders have healthcare and technology experience to build and launch such a system nationally.
