What Winslow Capital does

Winslow Capital Management, LLC is a Minneapolis-based growth equity investment firm founded in 1992, operating as a registered investment adviser and affiliate of Nuveen, LLC (itself a subsidiary of TIAA). The firm manages over $30 billion in growth equity strategies as of September 30, 2024, making it one of the largest active large cap growth managers in the United States according to eVestment rankings. Its client base consists exclusively of institutional and professional investors, including institutions, endowments, foundations, and other sophisticated investors seeking growth equity exposure.

The firm operates three core investment strategies: U.S. Large Cap Growth (a diversified equity strategy without sector or market cap preferences), U.S. Large Cap Growth ESG (an ESG-integrated variant of the core strategy), and Growth Capital (a private equity strategy focused on mid- to late-stage venture capital investments in disruptive private companies). Investment decisions are grounded in fundamental research through a proprietary "Winslow Science" framework combining peer group ranking, fundamental change analysis, and valuation methodologies. In November 2025, the firm implemented the Ridgeline cloud-native platform to consolidate investment operations functions.

Winslow Capital generates revenue through investment management fees charged on assets under management across its three strategies, with fees individually negotiated with institutional clients. The firm operates a direct institutional sales model, leveraging its Nuveen parent relationship for distribution while maintaining direct client relationships. The investment team averages 20+ years of industry experience, led by Chief Investment Officer Justin Kelly, CFA with 25+ years of leadership tenure.
