Philipp has a deep technical background from his Computer Science undergraduate degree from ETH Zurich and his graduate research experience on NLP at UC Berkeley. Wanting to learn Greek, he took 1-1 tutoring lessons and noticed how tailoring a session based on the student's interest and need can drastically accelerate learning. This experience prompted him to found Quazel (univerbal) with his two cofounders Sam and David to put an AI language tutor into everyone's pocket.
