AssetMark
AssetMark is a turnkey asset-management platform for over 9,000 independent financial advisors, managing roughly $100B in client assets.
AssetMark
AssetMark was founded in 1996 and is headquartered in Concord, California. Michael Kim took over as CEO in 2019, leading the firm through its NYSE listing (AMK) that July — the platform was previously majority-owned by private equity firms Genstar Capital and Aquiline Capital Partners (per the firm, 2019). AssetMark provides a complete technology, custody, and investment-management platform for independent RIAs. Advisors use AssetMark to access managed portfolios (mutual funds, ETFs, and SMAs), model management, billing, and compliance tools. The firm does not manufacture its own funds; it curates third-party strategies. Its platform supports fiduciary and commission-based models. Revenue comes from platform fees, custody charges, and advisory fees. AssetMark's scale is roughly $100B in total platform assets, with approximately 9,000 advisor relationships. It has one office in Concord. In 2025, AssetMark agreed to be acquired by GTCR for $2.7B, taking the firm private again (per GTCR, March 2025). The structural differentiator is AssetMark's exclusive focus on the independent RIA channel — it does not serve wirehouses, bank trusts, or insurance distributors. This makes its growth a direct read on the secular shift to independent advice. The company reports net flows and organic growth quarterly, a transparency rare for a platform of its type.
