Concentric has had the same focus for 25 years: delivering individually tailored, tax-optimized portfolio management across an entire book of business — without compromise, at scale.
How it started
Built from the ground up.
The firm was founded as Advisor Partners in 2001, in partnership with Andrew Rudd, Co-Founder and former Chairman and CEO of Barra. The technology, the trading infrastructure, the tax management logic — all of it built in-house, from the ground up.
Over two decades, that foundation was refined, expanded, and stress-tested across thousands of accounts and billions in assets — growing from a direct indexing capability into a full-spectrum portfolio management platform powered by the same proprietary optimization framework that has been running and improving since the beginning.
