About
I'm a Behavior Architect — a strategist, psychologist, and data scientist who has spent more than 20 years at the intersection of consumer research, behavioral economics, performance marketing, and cultural intelligence. My work in the beauty category spans brand strategy, consumer insights, and marketing science: helping beauty brands understand why people buy, not just what they buy.
Until recently, I was the Global Research Leader - Marketing Science at TikTok, working with some of the world's most iconic beauty advertisers to translate platform signals into brand growth. I've also held senior roles at Publicis Media (Performics), Leo Burnett, TBWA, PHD, Luminar Insights, and Egg Strategy. For my full profile, visit estebanribero.com.
How I Work
Core Expertise
Beauty consumers are emotionally driven, community-shaped, and trend-sensitive. I apply the tools of behavioral science and modern data analytics to help brands break through with precision and empathy.
Career
Research Leadership
At TikTok, I led the global Marketing Science Research team — a 40+ person research organization spanning multiple regions, with a $60M+ research investment over 4 years — responsible for the insights that beauty, CPG, and retail advertisers use to make media and creative decisions. Beauty & Personal Care was one of the most active verticals in my research programs.
The TikTok Insights tool — the platform beauty and CPG brands use to access consumer data
— is a system my team built. The creative measurement frameworks that define what good looks like
for short-form advertising (Attention Robustness, Attentive Ratio, Top Performing Content
Scoring) — my team built those too.
The AI-enabled tools to synthesize existing knowledge and help us think and ask better questions
- yep, my team and I developed those as well.
In short, When a beauty brand asks TikTok "what does the research say?",
they're often asking about work my team produced.
Beauty Category
Beauty is one of the most emotionally complex and rapidly evolving consumer categories. It sits at the intersection of identity, community, aspiration, and self-care — making it a perfect canvas for behavioral science and data-driven strategy.
"The most entertaining ads are also the most effective. On TikTok, you have to earn attention — and the way you earn it is by making something worth watching."— Esteban Ribero, The Long and Short (Form) of It Webinar, 2025
Research & Writing
Over the years I've published research and commentary on how consumer behavior, search, trust, and personalization intersect — themes that sit at the heart of modern beauty marketing.
In this global whitepaper and webinar (in partnership with System1),
I shared findings from the most comprehensive study of short-form video creative
effectiveness to date: 887 ads, 92,000+ TikTok users, 8 markets, and 350+ in-market
studies. The core message for beauty brands: entertainment and distinctive branding
aren't in tension — together, they're the most powerful combination on the platform.
Dull ads don't just underperform; they actively cost you conversions.
Several measurement frameworks (Attention Robustness, Attentive Ratio, and Top
Performing Content Scoring) were developed by my team to extend the applicability of the study.
Co-authored for WARC's LIONS Advisory series, this global whitepaper makes the case that
short-form video's most powerful — and most misunderstood — contribution to marketing
isn't reach or attention. It's brand building.
Drawing on cross-market evidence and primary research, I developed the central argument:
high-quality attention creates a qualitatively different environment for the transfer of
emotion in advertising. When attention is deeply engaged, brand affection is reset — and
that new affection becomes the anchor for all future brand experiences. For beauty brands
operating on TikTok, this isn't a media efficiency story. It's a brand-building imperative.
