Woodline Partners

Woodline Partners is an investment firm founded in August 2018 by former Citadel executives Michael Rockefeller, Karl Kroeker, and Matthew Hooker. Based in San Francisco with offices in New York, West Palm Beach, and London, the firm manages over $25 billion in assets across public equity markets. Woodline runs a fundamental, sub-sector specialist long/short equity strategy, employing 100+ investment professionals who conduct deep, bottom-up research anchored by corporate relationships, aiming to generate returns independent of broader market direction. Its coverage spans Consumer, Energy & Utilities, Financials, Healthcare, Industrials, and Technology, with holdings in public companies like AbbVie, Eli Lilly, and Regeneron. As a hedge fund trading public securities rather than making direct startup or buyout investments, concepts like "check size" or "notable investments" in the VC/PE sense don't directly apply.
