Joining now means being part of the team that is fueling that growth — building new relationships, winning logos, and shaping the next era of programmatic and the company.

The Role:

The Account Executive, New Business is a critical quota-carrying role responsible for driving new partnerships with agencies and brand-direct marketers. This team is a primary driver of company growth—prospecting, pitching, and closing net-new business—while working closely with sales development, marketing, sales leadership, and cross-functional partners to ensure client success.

What you'll do::
• Partner with sales leadership and SDRs to identify, engage, and win new agency and brand-direct accounts.
• Research, map, and connect with decision-makers using LinkedIn, CRM, and other prospecting tools.
• Build tailored pitches and presentations that align Quantcast’s value to client needs.
• Lead negotiations and close deals that deliver impact for both client and company.
• Collaborate with internal teams to ensure smooth onboarding and campaign execution.
• Respond to RFPs and develop proposals for first-time campaigns.
• Work with marketing on lead-gen initiatives and partner with the events team to increase awareness of Quantcast.
• Leverage prospecting tools (ZoomInfo, LinkedIn Sales Navigator, MediaRadar, etc.) to consistently build pipeline.
• Maintain strong pipeline hygiene across 50–100 accounts with disciplined stage progression.

Who you are::
• Minimum 3 - 5 years of sales experience, ideally in programmatic, digital advertising or march.
• Proven experience selling into media agencies and/or brand-direct marketers, with the ability to navigate multiple stakeholders and complex deal cycles.
• Strong hunter mentality — history of balancing prospecting, working warm leads and closing net-new business.
• Track record of success in quota-driven environments.
• Skilled communicator able to translate technical, multi-product and platform based concepts for executive-level audiences.
• Established relationships with small to mid-size agencies or brand-direct marketers (a strong plus).
