Former wearables exec raises $5.5M for a new kind of AI keyboard

Aina, started by ex-Ultrahuman VP Apoorv Shankar, raised $5.5M from Redstart Labs and 360 ONE. Shankar left Ultrahuman in 2025 disappointed by devices like the Rabbit R1 and Humane AI Pin. He believes the problem isn't how AI gathers information but how people give it instructions. Aina's first product, Dune, is a three-key keyboard that adapts to context.
