Our story

Developed over 25 years. Focused on one thing.

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.

Proprietary technology and risk management come together to form the foundation of Concentric’s optimization framework.

Over 25 years in the making.

What began as Advisor Partners is now Concentric — a portfolio management solution that continues to be refined 25 years later.
