William López

William López leads BuildWithin, an employment services technology company and U.S. Department of Labor National Apprenticeship Intermediary. Under his leadership, BuildWithin has grown into a national platform that government agencies, workforce boards, and employers use to match individuals to jobs, manage registered apprenticeships, and replace fragmented systems with a single system of record.

A lifelong resident of the DC region, William grew up in Arlington, Virginia and graduated from Marymount University. He was a founding team member of Phone2Action (later Capitol Canary), the Arlington-founded advocacy technology company that scaled nationally before its acquisition.
