Angèle joined Impatient in 2026 as the firm’s first investor. She spent the previous three years as an early-stage investor at Slow Ventures, where she helped build the firm’s deep and hard tech practice and led its work on physical-world themes spanning energy, maritime, the low-altitude economy, and more.
Angèle graduated cum laude from the Dual BA Program between Sciences Po Paris and Columbia University, where she majored in Financial Economics and also studied sociology, political science, and international relations.
Outside of work, you’ll most likely find her on a 10-mile walk somewhere in nature, at a jazz club with friends, or planning her next trip home to France.
