co-founder @ userjourneys.ai - we ship experiments for consumer tech

San Francisco, California, United States

About

we run experiments for consumer tech companies. today, product representations live in the heads of product people, and decisions get made on episodic judgment. but every interesting structure in the universe, like financial markets, science, the human brain, is recursively self-improving. we're giving that structure to product development. we build a graph-based representation of your product and how users interact with it. from that representation, we propose experiments that reveal which directions users are pulling the product. every experiment sharpens the graph. the structure is able to look at itself, poke holes, and improve. your role as product owner is to guide it by approving or rejecting experiments based on your taste and long-term vision.
