Agency Lead

At MNTN, we put our people first, full stop. This allows our company culture to be defined by our team members and their shared values, like trust, ambition, quality, radical honesty, and compassionate leadership. It’s why we all really love working for the Hardest Working Software in Television™ (and also why we were named one of Ad Age’s Best Places To Work in 2026.)

We pride ourselves on bringing unrivaled performance and simplicity to Connected TV advertising. Our self-serve technology makes running TV ads as easy as search and social, helping brands drive measurable conversions, revenue, site visits, and more. It’s what led MNTN to being named one of Fast Company's Most Innovative Companies in 2023. You can learn more about us and everything we do by visiting https://mountain.com/.

We’re committed to innovation that empowers, not replaces. At MNTN, AI is a tool for growth, enhancing efficiency while keeping a people-first approach. Our goal is to streamline workflows and drive new solutions—without compromising the human element that makes our company great.

So if wanting to do more, own more, and make a bigger impact comes naturally to you, then you may be the person we're looking for to join us in our next stage of growth.

As an Agency Lead at MNTN, you'll lead the development and growth of high-value agency partnerships, helping agencies unlock growth for their clients through Connected TV. You'll own complex, full-cycle sales opportunities and serve as a trusted strategic advisor on how agencies plan, buy, and scale CTV across their client rosters.

You'll focus on winning scalable new agency partnerships and expanding MNTN's footprint within strategic agency accounts. You'll build programs around co-marketing, technology integration, enablement, and joint business planning, while developing a deep understanding of each agency's business, media strategy, and growth priorities. You'll provide a consultative, executive-level experience that earns trust with agency leadership and the client teams they represent.

You'll work alongside a dedicated Agency Partner Manager in a shared-pod model, from commitment through onboarding and across the full agency lifecycle, jointly accountable for growing each agency's business on MNTN and expanding the partnership across its client roster. Together, you'll own a shared revenue target and help shape one of MNTN's fastest-growing partner segments.

• Build and manage a strong pipeline of qualified agency opportunities through strategic account planning, targeted prospecting, executive referrals, inbound demand, and industry events and conferences.
• Lead executive-level discovery and business planning conversations to understand an agency's client portfolio, commercial priorities, media planning process, and the role CTV can play in its broader growth strategy.
• Develop compelling, tailored platform demonstrations and business cases that address agency workflow needs, including multi-client management and reporting, while connecting MNTN's value to end-client performance goals.
• Serve as a trusted advisor on Connected TV, performance marketing, and how agencies can diversify beyond traditional channels and differentiate their offering to clients.
• Expand strategic agency partnerships by identifying and activating net-new brands and client teams within their roster, working alongside your Agency Partner Manager, who owns growth of brands already running.
• Partner closely with your Agency Partner Manager and cross-functional teams to ensure new agencies and their clients launch successfully, with scalable onboarding and growth plans across complex client portfolios.
• Navigate senior stakeholders, multiple buying centers, and longer decision cycles to establish MNTN as a repeatable, strategic media channel across an agency's client portfolio.
• Own rigorous forecasting, pipeline management, account planning, and CRM hygiene while leveraging AI, Salesforce, and modern sales tools to improve productivity and decision-making.
• Bring the voice of the agency to MNTN by sharing competitive intelligence, market trends, and partner feedback that influence the agency go-to-market strategy, product roadmap, and partner program.
• Mentor Agency AEs, share repeatable best practices, and raise the quality of prospecting, discovery, executive engagement, and deal strategy across the team.
