## About

Altair Advisers was established in 2002 by four former Arthur Andersen consultants. Steven B. Weinstein serves as chairman while Rebekah L. Kohmescher holds the CEO role. The firm supplies investment counsel, financial planning and governance support to its clients. Portfolios combine allocations to private equity, real estate, hedge funds and fund-of-funds vehicles. The firm maintains two internal vehicles, Altair Real Estate Fund and Altair Private Equity Fund, both based in Chicago. Geographic exposure remains limited to North America. No specific co-investors or portfolio company names appear in public materials. Team size and office count beyond the Chicago headquarters are not disclosed. The firm participates in the Family Office Exchange and maintains professional designations through the Investment & Wealth Institute and Financial Planning Association. Philanthropic ties include the Art Institute of Chicago and the Chicago Symphony Orchestra. The multi-family office structure separates client mandates from any single-family wealth source and relies on open-architecture manager selection rather than proprietary funds.
