Twenty-five years building product. Now fully in on AI.

NameBill Davenport
RoleFounder / Operator
BaseWorcester, MA

I'm a product executive with 25+ years building technology platforms from the ground up — today I'm fully immersed in applied generative AI.

What drives me: building products that actually change how people make decisions. Whether that's giving investors better tools for corporate governance, discovering interesting stocks for further analysis, or making complex financial planning accessible to anyone planning for retirement — I'm drawn to problems where AI can create a step-change in investor outcomes.
