Biosynq, a Bay Area-based tech startup, launched its crowdsourcing 911 app Monday in Roseville.
The "Alert-360" launch event was on the 47th anniversary of the very first 911 call.
Richard Diamond, the company's founder and CEO, explained that the app works based on proximity. Calling 911 through the app also alerts other nearby users, in the hopes that aid could be rendered more quickly.
"Alert-360" will also be launching in Oakland.
