401GO raises $33M to scale owned 401(k) platform

401GO has secured a $33 million Series B round to accelerate deployment of its vertically integrated 401(k) technology and broaden distribution through advisors, payroll providers and HCM partners. The round was led by Centana Growth Partners, with continued backing from existing investors Next Frontier Capital, Rally Ventures and Impression Ventures.

The Salt Lake City–based fintech has built its service around a fully owned recordkeeping and administration stack, positioning itself against incumbents that stitch together legacy recordkeepers and third‑party compliance modules. Dan Beck, CEO and co‑founder, argues this integration reduces implementation friction for brokers and employers while enabling tighter payroll connections and more predictable pricing.

Investors pointed to the company’s traction as a key rationale for the follow‑on funding. 401GO now reports serving more than 5,000 customers, supporting roughly 50,000 plan participants and overseeing in excess of $1 billion in assets. The new capital will expand product development, hire across engineering and client success, and accelerate partner integrations with HR and payroll platforms.

“We see a structural gap in retirement technology for small and micro plans,” said Ben Cukier of Centana Growth Partners. “401GO’s approach—owning the stack and focusing on embedded distribution—matches the way advisors and payroll vendors want to distribute benefits today.”

Macro drivers underpinning the investment include regulatory nudges such as auto‑enrolment mandates in certain jurisdictions and the proliferation of state‑level retirement programs. Industry research cited by the company forecasts the universe of small 401(k) plans (assets under $5m) will climb from about 600,000 to more than one million by 2029, creating a large addressable market for modern, low‑friction providers. PlanSponsor survey data also points to faster growth among smaller plans, often outpacing legacy platform capacity.

With fresh capital in hand, 401GO will push on integration velocity, expand its distribution partnerships and continue building features aimed at advisors and white‑label HCM channel partners. The company’s next phase will test whether owning the technology stack translates into sustained cost advantages and faster deployment at the scale required by the small‑plan market.
