About Brad Gillespie

Brad Gillespie is an early builder of IA Ventures who has been shaping the firm's strategy since 2010 and focuses on backing companies before product-market fit across an unusually broad technical scope spanning AI, robotics, biotech, and data infrastructure. He's known among other VCs for always betting on the founder and has been involved with several multibillion-dollar data infrastructure platforms like The Trade Desk and Datadog from their true seed stages.

IA Ventures was founded by former Wall Street derivatives trader Roger Ehrenberg on an "information arbitrage" thesis, importing quantitative hedge fund pattern recognition and risk management into seed investing in data infrastructure companies. The firm was one of the earliest dedicated "big data" seed funds starting in 2009-2010 and is known for unusually concentrated, conviction-driven investing through small boutique funds that allow partners to spend more time per founder than typical larger platforms.
