Background
Aaron Keller is a Partner at Insignia Capital Group, a San Francisco-based private equity firm focused on building exceptional companies in the consumer and business services sectors. He joined Insignia in 2016 and is responsible for identifying and evaluating investment opportunities, executing deals, and collaborating with portfolio companies on operational initiatives. Aaron currently serves on the boards of Century Snacks, Fueled, Dualboot Partners, and Chocolate Works, and previously served on the boards of WillowTree (exited 2023) and Market Performance Group (exited 2024).
Prior to joining Insignia, Aaron worked as an Analyst in the Leveraged Finance Group at Deutsche Bank, where he developed his foundation in deal structuring, credit analysis, and capital markets. He graduated summa cum laude from Georgetown University with a Bachelor of Arts in Economics.
Over his tenure at Insignia, Aaron has been involved in the firm's growth from an emerging lower middle-market fund to a platform that has completed over $5.8 billion in total transaction value across 35+ middle-market transactions. In October 2025, Insignia closed its newest fund with over $500 million in total capital commitments, reflecting the firm's expanding footprint in the private equity landscape.
Investment Thesis & Focus

Insignia seeks investments of at least $15 million in profitable, growing companies, and routinely evaluates smaller strategic add-on acquisitions for its portfolio companies.
