Matter Family Office

What Matter Family Office does

Matter Family Office is an independent, fee-only multi-family office founded in 1990 in St. Louis by Katherine Lintz, serving ultra-high-net-worth families across the United States. Following its August 2025 merger with Denver-based IWP Family Office (founded 2005 by current CEO Charlie Willhoit), the combined firm manages over $10 billion in assets under advisement for approximately 150 client families spanning 34 states, supported by 100+ professionals across offices in St. Louis, Denver, Dallas-Fort Worth, and Raleigh-Durham-Chapel Hill. The firm operates as an SEC-registered investment adviser under Matter LLC, delivering five integrated service modules — Family Operations, Wealth Planning, Investment Management, Family Learning & Communication, and Project Management — designed to coordinate the full spectrum of UHNW financial and family governance needs.

The firm's underlying technology is a third-party-stack architecture rather than a proprietary platform: client portals run on Tamarac (legacy Matter clients) and Addepar (legacy IWP clients), account aggregation is provided by Yodlee, and consolidated reporting plus advisor coordination is delivered through human-driven workflows. There is no disclosed proprietary software product, no AI/ML capabilities, and no developer-facing API. Matter's competitive differentiation rests on its interdisciplinary advisory model, its proprietary 25+ year Family Learning & Communication curriculum, and its decades-long embedded relationships with multi-generational family clients rather than on technology differentiation.

The business model is fee-only advisory: revenue is generated through recurring advisory and management fees on assets under advisement plus fixed-fee engagements for planning, project management, and family learning work. No commissions are earned on product sales, aligning incentives with client outcomes. Go-to-market is relationship-driven, relying on referrals from existing clients, Centers of Influence (estate attorneys, CPAs, insurance consultants), media visibility in top-tier financial publications, and industry conference presence. The firm received a strategic capital investment from BW Forsyth Partners (the investment arm of Barry-Wehmiller) in October 2024 to fund organic growth and future acquisitions, and the firm has signaled continued geographic expansion following its June 2026 entry into the Raleigh-Durham-Chapel Hill market.
