Cogito LLC logo is based on two concepts: Ensō and Monad.
In Zen, Ensō (円相, "circular form") is a circle that is hand-drawn in one or two uninhibited brushstrokes to express a moment when the mind is free to let the body create.
Monad (from Greek μονάς monas, "singularity" in turn from μόνος monos, "alone") refers, in cosmogony, to the Supreme Being, divinity or the totality of all things.
