MNTN is a Connected TV advertising platform that simplifies TV ad buying for brands through self-serve technology. As Senior Manager of Agency Partner Management, you will lead a team of Agency Partner Managers responsible for driving growth and performance across independent agency portfolios on the MNTN platform.
You will own your team's revenue targets, forecast gross media spend and expansion, and ensure every account has a clear growth plan. Your responsibilities include leading, coaching, hiring, and ramping Agency Partner Managers while driving accountability for spend growth, new business, and partner health. You'll conduct portfolio reviews, pipeline reviews, and one-on-ones that drive measurable action. You'll develop repeatable onboarding and growth playbooks, set portfolio segmentation and coverage strategies, and prioritize training and enablement resources that build platform fluency among partners.
You will build direct relationships with agency budget decision-makers, lead escalations and critical reviews, and proactively track spend, performance, engagement, and staffing changes to identify and mitigate risks early. You'll partner with Sales, Partner leadership, and Product Marketing to resolve issues, shape the roadmap, and improve team processes and tools. Success means meeting or exceeding gross media spend and new business targets with accurate forecasts, developing a healthy and increasingly self-sufficient portfolio, and positioning your team as strategic advisors to agency partners rather than a support resource.
MNTN values people-first culture, trust, ambition, quality, radical honesty, and compassionate leadership. The company was named one of Ad Age's Best Places To Work in 2026 and Fast Company's Most Innovative Companies in 2023.
