## About

Katherine B. Lintz established Matter Family Office in 1990. The firm grew from her certified financial planning practice that served St. Louis clients. Wealth origin traces directly to that advisory business rather than an operating company or inheritance. Matter deploys capital through fund commitments, direct co-investments and SPVs. Asset classes include private equity, private credit, real estate, hedge funds and commodities. Confirmed positions include allocations to Generation Investment Management global and Asian equity funds. The firm maintains exposure in North America with additional real-asset holdings in Atlanta and Dallas. Investment stages span venture capital, growth equity and buyouts. The firm reports $10B under management. It operates from St. Louis with a merged entity led by Charlie Willhoit as CEO. Adjacent vehicles include Flourish - A Family Foundation and the Lintz Family Zoo Endowment. In October 2024 BW Forsyth Partners took a strategic minority stake. Katherine Lintz has served on the boards of the Saint Louis Zoo Association and St. Louis Children's Hospital Foundation. Matter maintains membership in the UHNW Institute, Family Wealth Alliance, Purposeful Planning Institute, Family Office Exchange and YPO. These networks supply co-investor relationships and governance resources that sit outside standard fund-of-funds channels.
