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. This CSM will manage a portfolio of accounts and will be responsible for making the InfoSum platform 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.   What you'll need: Industry Experience:   A minimum of 3-5 years in a customer success or account management role within the Ad Tech industry.   Paid Media Expertise:   Solid understanding of the paid media marketplace, including how decisions are made, how money moves, and the competitive landscape (DSPs, SSPs, data platforms). Candidate doesn't need to know everything but should know "a sliver of it" and be hungry to expand.   Business & Outcome Focus:   Ability to articulate success through business outcomes and metrics (e.g., revenue growth, usage increase) rather than just relationship management.   Usage-Driven Mindset:   Understanding that renewals are earned through continuous value delivery and driving platform usage, not through a once-a-year conversation.   Technical Aptitude:   Technical understanding of how Ad Tech platforms work. While not a coding role, the candidate must be able to grasp technical concepts to be a credible partner to clients and internal teams.   Attitude & Hunger:   "Be hungry. Attitude is most important. Attitude and talent." — strong desire to learn, grow, and take ownership. Proactive, startup mentality.   Career Commitment:   Preference for candidates who have demonstrated commitment by staying with a previous company for at least two years, showing they can deeply learn a technology.   Who you are: You're open : We are inclusive and collaborative; we encourage the free exchange of ideas; we respect and celebrate diverse
