About Sert Media

Sert Media started with a simple belief: great creative work and strong performance data are natural partners, not rivals. In 2018, our founder Scott Hartley saw a gap in the agency world. Too many firms picked sides—pretty work that didn't drive results, or metric-chasing that ignored creative quality. We built something different. Strategy comes first. Creative serves a purpose. Every campaign is measured by what it achieves.

Our early years were defined by scrappy growth and deep client bonds. We started with a lean team of six in a shared desk space in downtown Los Angeles. We took on bold projects from e-commerce brands, B2B SaaS companies, and startups. We refused to separate strategy from execution. We didn't hand off briefs; we built lasting partnerships. Our first client, a fashion e-commerce brand struggling with acquisition costs, saw their CAC drop by 40% in six months through audience segmentation, refined messaging, and cohesive creative campaigns. That success became our template.

By 2020, as the world shifted to remote work, we became fully distributed. We leaned into it, building a team that could work across time zones and tap top talent anywhere. We hired strategists from London, designers from São Paulo, and performance specialists from Singapore—all united by our core values and focus on client outcomes. Our team grew to 30 by 2022. Our client roster expanded to include enterprise brands managing multimillion-dollar budgets.

Today, Sert Media serves over 200 client brands across industries from technology and finance to consumer goods and nonprofits. We have driven over $1 billion in attributed client revenue through campaigns that are as data-rigorous as they are creatively bold. We remain guided by day-one principles: transparency in reporting, fresh thinking in approach, and an unwavering drive to deliver results that matter.
