Co-Founder at Neurosity
Insights & ideas
Neurosity's core idea, as Keller describes it, is that brain activity can be captured and translated into actionable feedback the way a speedometer reads a car's speed, letting people see when they are "over speeding" or "under speeding" mentally and adjust accordingly [1][2]. He argues that most lab-grade BCIs rely on hardwired setups or shielded rooms, so Neurosity's innovation was pushing the compute onto the wearable device itself to create a stable, autonomous system capable of local pattern recognition [1]. Keller frames BCIs as a translator between brain activity and computers, and envisions a future high-bandwidth interface where computers could learn from humans faster than humans learn from each other [1].
He traces his motivation to his father's questions about why computers don't learn from people, and to his time automating airplane assembly at Boeing, where he saw how a "mental tap" could stop dangerous robot-human collisions faster than a person could yell or hit a button [1][2]. Keller says he first tried a software-only approach but failed to make it reliable, concluding that "neurosity exists because it has to" since the underlying hardware needed didn't yet exist [2]. He also emphasizes designing hardware people are proud to wear, treating device aesthetics as part of a user's personal identity and brand [2].
