## About

Stuart Robertson founded Sharebuilder 401k in 2007, initially building the firm as a subsidiary of ING before it passed to Capital One's ownership. In 2020, Robertson executed a management buyout that returned the company to independent control and re-established it as a registered investment advisor under Delaware law. The firm has since operated from Seattle without external institutional backing. The firm delivers retirement-plan products designed explicitly for small and medium-sized businesses, including model-portfolio construction and commodity-ETF exposure accessible to plan participants. Its service model covers the self-employed through mid-market employers, with plan-administration, recordkeeping and fiduciary support provided under a single RIA roof. Following the 2020 buyout, Robertson remains CEO and principal owner. The firm maintains professional affiliations — he contributes to the Forbes Finance Council and participates in the Estate Planning Council of Seattle — but publicly discloses no adjacent vehicles, philanthropic foundations or external club memberships. The 2020 management buyout is the firm's structural differentiator: few retirement-plan providers of its vintage have transitioned from captive bank subsidiary to founder-owned RIA. That governance change reset the firm's fiduciary posture and aligned equity entirely with its operating CEO, an arrangement distinct from both PE-backed roll-up platforms and mutual-company competitors.
