Bobby Murphy

Bobby Murphy grew up in the San Francisco Bay Area and studied mathematics and computational science at Stanford University, where he met Evan Spiegel. Murphy is widely described as the technical architect of Snapchat's early infrastructure, building the original iOS application and server backend while Spiegel drove product design and business strategy. Murphy's engineering background in computational mathematics informed Snap's early approach to image processing and compression, which would later evolve into the company's augmented reality capabilities.

Bobby Murphy co-founded Snap Inc alongside Evan Spiegel and serves as the company's Chief Technology Officer, a role he has held since the company's founding. Murphy built the first version of the Snapchat application and has overseen the development of Snap's technology infrastructure, including its augmented reality Lens platform, Lens Studio developer tools, and backend systems that support billions of daily snaps. Murphy is significantly more private than Spiegel and rarely makes public statements, but his influence on Snap's technical direction — particularly in AR development — is considered foundational by the company's engineering team. Like Spiegel, Murphy holds Class C supervoting shares that give the two founders effective control over corporate governance.
