Wispr AI
Building the Voice OS - a voice-native computing system that makes interacting with devices as effortless as talking to a close friend, moving from screen-first to voice-first experiences.
Founding Story
Co-founders Tanay Kothari and Sahaj Garg, who worked together at Stanford's top AI labs under Andrew Ng and Stefano Ermon, initially started Wispr in 2021 with the vision to build a wearable device that would allow users to type just by mouthing words silently - a thought-powered neural interface inspired by Tanay's childhood obsession with Iron Man's Jarvis. After three years of designing this wearable using non-invasive neural interfaces that read biosignals from the body (specifically EMG sensors), they realized AI technology wasn't advanced enough yet. They pivoted to focus on software, building Wispr Flow as the foundational voice layer to eventually enable their vision of a voice-native operating system.
