Rockefeller Capital Management (RCM) is an independent wealth management and financial services firm established in 2018 when CEO Greg Fleming — a former senior executive at both Merrill Lynch and Morgan Stanley — partnered with the Rockefeller family and Viking Global Investors to acquire Rockefeller & Co., a multi-generational family office with roots tracing to John D. Rockefeller's 1882 family office. Today, the firm operates as a full-service platform combining family office services, asset management, and investment banking, serving ultra-high-net-worth individuals, families, institutions, and corporations.

What does Rockefeller Capital Management offer?
RCM operates through three integrated business lines, each serving overlapping client segments across the wealth and corporate spectrum:
- Rockefeller Global Family Office — wealth management, trust and fiduciary services, financial and estate planning, and multi-generational family office services for ultra-high-net-worth individuals and families, delivered through affiliated advisor teams that operate under the Rockefeller brand
- Rockefeller Global Investment Management — asset management including approximately $20 billion in proprietary strategies spanning global, international, and US large-cap equities, small and SMID-cap equities, long-short equity, private equity, investment-grade fixed income, and municipal high yield, alongside outsourced CIO services and third-party manager access
- Rockefeller Global Investment Banking — mergers and acquisitions advisory, capital raising, strategic and financial planning, and shareholder advisory and defense for private and public companies, including advisory on sports franchise transactions
The firm's growth strategy has centred on recruiting breakaway advisory teams from wirehouses and other large institutions. Fleming has described the primary client target as families who have created wealth through building businesses, positioning the family office as a natural landing point for entrepreneurs navigating liquidity events and wealth transfer.
Rockefeller Capital Management in the market
RCM competes at the ultra-high-net-worth end of the wealth management market, where a small number of multi-family offices, large private banks, and independent platforms vie for clients typically holding more than $10 million in investable assets. Its principal differentiator is the Rockefeller brand itself — one of the most recognised names in American financial and philanthropic history — which the firm has leveraged to recruit wirehouse advisors and attract clients who associate the name with institutional credibility, discretion, and multi-generational stewardship. AdvisorHub named RCM one of the 50 RIA firms to watch in 2026, noting its aggressive pursuit of high-end wirehouse teams and geographic expansion under Fleming's leadership.
RCM's competitive position is also shaped by its three-pronged platform model, which distinguishes it from pure-play family offices and RIAs. The ability to offer family office services alongside proprietary investment management and independent investment banking in a single firm is relatively rare, and Fleming has cited this integration as a key reason clients consolidate relationships at the firm. The combination is particularly relevant for entrepreneurs and family business owners who need both wealth planning and corporate advisory services across different phases of a business's lifecycle.
A recapitalisation in late 2025, which brought in Mousse Partners and other new investors alongside the firm's existing backers, provided additional capital for recruiting and acquisitions and signalled a new phase of geographic and international expansion. Fleming has indicated plans to build out the firm's presence in Miami, Minneapolis, Las Vegas, and other markets where the firm believes it is under-scaled relative to the concentration of wealthy families, and has identified Singapore and the Middle East as early international priorities. Competition at this level of the market has intensified, with other ultra-HNW-focused firms including Corient and AITI Global also expanding their international reach.
