Kosta Eleftheriou is a serial founder and engineer based in San Francisco with a decade of focused expertise in text input, accessibility, and novel user interfaces. He has repeatedly turned research-backed prototypes into award-winning products—three of his startups have been acquired by Google, Pinterest, and Formax Group—and his keyboard work (Fleksy, FlickType, BlindType) has reached millions and earned high-profile accessibility endorsements. Pragmatic and user-centric, he blends hands-on engineering, IP strategy, and product design to solve hard interaction problems across platforms, from smartwatches to consoles. Known as a tinkerer who values pruning as much as building, he also has deep experience improving developer velocity and growth systems at scale. He enjoys mentoring and communicating vision, and often bridges academic ideas (MSc-level natural computation background) with practical, production-ready software.
