Since joining Arc as CEO in 2018, Soche has transformed the agency with a bold new brand positioning — Irresistible Commerce — establishing Arc as the gold standard in commerce. Under her leadership, Arc’s client portfolio has surged by more than 150% with major wins including CPG giants Kraft Heinz and Colgate, earning her recognition as a 2020 Path to Purchase Executive of the Year.
Soche played a pivotal role in integrating Epsilon and Catapult into Publicis Groupe, uniting data and creative capabilities to double Arc’s size and elevate it into one of the world’s most innovative commerce agencies. This strategic vision contributed to Publicis Groupe’s recognition as a Leader in The Forrester Wave™: Commerce Services in 2024.

A people-first leader, Soche has fostered a culture that prioritizes employee well-being and belonging, resulting in Arc being named an AdAge Best Place to Work in 2023. In 2024, after her own breast cancer diagnosis, she became a vocal advocate for the Publicis Groupe’s Working with Cancer initiative, collaborating with the American Cancer Society’s Making Strides Against Breast Cancer® program to raise awareness and drive fundraising efforts.

Soche’s impact and influence were further recognized in 2025 when she was honored as a She Runs It Working Mother Trailblazer, celebrating her commitment to redefining leadership while championing work-life integration for women in the industry.
