We’re thrilled to share that Ad Age has named our own Zafreen Zerilli to the 2025 Media Buying Power List! This honor recognized Zafreen’s work redefining what analytics can do for modern media—transforming complex data into clear, actionable insights that drive real, profitable growth.
BUILDING THE FUTURE OF MEDIA INTELLIGENCE
What sets Zafreen apart isn't just her expertise—it's her ability to build. Over eight transformative years at Stella Rising, she's developed a suite of proprietary tools that embed advanced analytics into every stage of media planning:
- Spark uses predictive forecasting to project revenue with remarkable precision.
- Halo optimizes channel planning to ensure every dollar works harder.
- Pulse delivers MMM-backed performance dashboards that fuel real-time strategy decisions.
- Prism, a first-party customer modeling tool, unlocks lifetime value and behavioral segmentation at scale—critical in a post-cookie world.
These aren't just analytics tools. They're strategic growth engines that merge AI, machine learning, and human insight—reflecting our commitment to innovation that drives measurable business outcomes.
SOLVING COMPLEX PROBLEMS WITH CREATIVITY
When health insurance marketplace Covered California needed to balance enrollment growth with equitable reach across underserved communities, Zafreen didn't just run one model—she built three. The result? A 12% year-over-year ROAS improvement, a Digiday Award win, and a measurement framework that proved performance and inclusivity aren't mutually exclusive.
Zafreen believes that measurement should never be an afterthought. In her words: “The most effective media buyers never commit to a new channel without first understanding how performance will be measured and tied back to business outcomes."
To Zafreen: this honor celebrates your brilliance, your passion, and your relentless commitment to raising the bar. Thank you for showing what's possible when analytics meets ambition, and for being such a vital part of Stella Rising! 💫
