About the role

The Customer Success Manager (CSM) will be a key member of the North American Client Services team at InfoSum, responsible for driving the adoption and usage of InfoSum's data collaboration platform. This role is critical as InfoSum transitions from a flat-rate SaaS model to a usage-based revenue model, placing heavy emphasis on driving platform adoption and client engagement. After the sales team closes a new contract, the CSM takes ownership of the client relationship. The CSM will manage a portfolio of accounts and ensure the InfoSum platform becomes indispensable to clients through strong relationship building, understanding their business goals, and aligning them with InfoSum's capabilities. The core focus is on ensuring client stickiness, securing renewals, and identifying expansion opportunities. The CSM will manage a portfolio of approximately 16-20 accounts, including a mix of major brands, publishers, and data providers, alongside smaller customers.
