About
Brian Sparker

Hi, I'm Brian

I'm a product leader who loves building things that make technology feel human. For more than a decade, I've helped teams turn complex systems into simple, valuable experiences that people actually want to use.

Most of my work has centered on search, discovery, and AI — figuring out how to make information more useful, more contextual, and more connected. At You.com, I've played a key role in shaping how AI applications power modern search and knowledge experiences, helping the company grow into a leader in this space.

Before that, I spent years in e-commerce and marketplaces, building search and recommendation products that made it easier for people to find what they were looking for. I studied Marketing and completed my MBA at Boston University, where my focus was on innovation, product strategy, and the intersection of business and technology.

Across all of it, I've stayed focused on the same goal: understanding what people need, then building the bridge between great technology and real human value.
