As Head of Independent Agencies at X (formerly Twitter), you will own the independent and performance agency portfolio and third-party partnerships, driving revenue growth through strategic relationships, education, and direct collaboration with agencies and partners. You will develop and maintain strategic relationships across independent and performance agencies, partnering with Client Partners, Mid-Market sales, product, and measurement teams to deliver cohesive engagement plans. Key responsibilities include increasing revenue across agency-driven accounts, building trusted partnerships, and facilitating active communication between agencies and X. You will develop and deliver educational programs including Lunch & Learns, product updates, and bootcamp-style training on products, brand safety, measurement, and advertising best practices. You'll demonstrate how and why people use X to help marketers identify authentic brand use cases, and ensure agency feedback is conveyed back to Marketing, Product, and Measurement teams for product development insights. Additionally, you will own and grow the third-party measurement partner portfolio, building senior relationships aligned to X's product and commercial priorities. You'll translate measurement capabilities into clear value for partners and practical guidance for agencies, driving joint go-to-market initiatives while keeping partner and agency messaging coordinated.
