ATG Capital Management

What ATG Capital Management does

ATG Capital Management LP is a privately-held investment firm founded by Gabi Gliksberg that manages investment vehicles for select accredited investors. The firm invests primarily in public equity markets using alternative strategies, with a core focus on shareholder activism and direct, constructive engagement with portfolio companies. Notable campaigns include a successful 2021-2022 effort to declassify the board of Texas Pacific Land Corporation (passed with 56% of shareholder votes), Delaware litigation to obtain stockholder inspection of books and records, public opposition to a dilutive share authorization increase at TPL in November 2022, and an ongoing 2026 activist campaign against ProCap Financial's proposed merger with CFO Silvia.

The firm operates with a small team (1-10 employees) and does not have a disclosed technology platform; its "product" is a single integrated investment management offering rather than a modular platform. Revenue mechanics rely on management fees and performance-based compensation tied to investment returns, consistent with a traditional alternative asset manager. Go-to-market is direct relationship-based with accredited investors, supplemented by a public-facing media presence (Twitter/X @ATG_Capital, PR Newswire press releases, and coverage in Bloomberg, Barron's, and Dallas Business Journal) that doubles as a brand-building channel for the firm's activism thesis.

The firm's competitive position is built around the founder's track record and an exclusive legal partnership with Lowenstein Sandler's Securities Litigation Group. Headquartered in Sunny Isles Beach, Florida (with prior offices in Fort Lauderdale and Chicago), the firm is owner-operated, with no disclosed institutional investors, parent company, or external ownership structure. Operating geography is the United States, and the firm is classified as a Limited Partnership under Florida domicile.
