She joined when Mistral had only about 20 people and, over nearly three years, helped build its DevRel team as the company grew past 1000 employees. She thanked founders Arthur Mensch, Guillaume Lample and Timothée Lacroix for the opportunity but did not disclose her next step. Her exit is a notable talent-movement signal for the high-profile French AI firm.
