Sameer Shariff

Sameer Shariff is the co-founder and CEO of Cambly, a San Francisco-based edtech platform that connects English learners worldwide with native-speaking tutors via on-demand video chat. A Princeton and Stanford-educated engineer who spent five years at Google, Shariff co-founded Cambly in 2012 after a trip to Argentina revealed how dramatically conversation practice accelerates language fluency. After a failed Series A attempt, he drove Cambly to cash-flow positivity without touching raised capital - then raised $60M from Benchmark, Bessemer, and others once the company no longer needed it. Cambly has ranked #1 in app stores across 150 countries and reaches an addressable market of 1.5 billion people seeking English fluency.
