BY01 builds Cortexes for operators who refuse to rent their thinking.

Companies are still figuring out what to do with AI. The pattern that keeps emerging in the ones who go deep: build a brain — a layer that holds the voice, the customers, the decisions nobody wrote down. Agents read from it. Tools follow orders. The Cortex is that brain.

BY01 is an AI Operations Studio. Half research, half agency in formation. The research is the cortex itself — a living operating brain that HHG ventures already run on — published outward through the Cortex series on Substack. The agency forms around concrete engagements, helping companies find their cortex-shape from the inside, one foothold at a time, on the way to something productized.

We don't market this loud. By application. Small number of engagements per year.
