Senior Growth Manager, Korea

About KIMARU Talent: KIMARU Talent is a boutique executive search firm working with startups and growth-stage companies in AI, gaming, technology, and advertising. We take on fewer clients so we can go deeper on each search — real understanding of the role, the team, and what "yes" looks like for both sides. We're not generalists who'll take any search. We focus on leadership and critical individual-contributor hires — the roles where getting it right changes the trajectory of the startup. That depth is why most long-term clients give us access to their ATS, Slack, and internal comms. We're not a vendor you check in with weekly. We operate like an internal recruiter with an external network. About the Company Our client is an AI-native advertising platform at the intersection of machine learning, programmatic media, and full-funnel mobile growth. The company focuses on measurable business outcomes rather than impressions, and it has compounded growth quarter over quarter since 2024. In Korea, revenue has grown roughly 3x over the past two years, and the company is now expanding its local team. The Role The Senior Growth Manager will own a portfolio of strategic Korean accounts and drive revenue growth and retention across them. This is a senior individual contributor role with full ownership from day one. There is no existing playbook, so the person in this seat will build one. The portfolio is currently gaming-heavy.
