01 — About Us
401kinvestmentadvisers.com was founded by former 401(k) plan administrators who saw one scandal: 78% of American workers overpay fees and sit in the wrong target-date fund. We fixed it. As fee-only Registered Investment Advisers, we legally must put you first — no kickbacks, no proprietary funds, just data-driven allocation.
