CEO Evan Spiegel is the public face of Snapchat parent company Snap Inc., but Bobby Murphy also wields considerable power as its cofounder and chief technology officer.
Together, Murphy and Spiegel own the vast majority of Snap's voting stock, giving them complete control over the company's future. Now that Snap has gone public, Murphy has an estimated net worth of around $5.4 billion.
