Objectives & Goals

SHEIN’s Challenges 

Starti Strategy

01//
Hyper-Targeted Audience Segmentation

New Users

- Leveraged first-party data to target viewers of fashion hauls, award shows, and Gen Z-focused series on FAST platforms like Roku and Tubi.  

- AI Cohorts: Built “Trend-Hungry Gen Z” (18–24) and “Value-Driven Millennials” (25–35) segments using CTV Signals: Viewership of Love Island, Selling Sunset, and fashion TikTok compilations on FAST channels.  

- Purchase Intent: Mobile searches for “trending OOTD,” “festival outfits,” and competitor app usage (ASOS, Zara).  

- Starti’s AI analyzed SHEIN’s top 10% spenders (avg. $200/month) to find “hidden twins” in LATAM/MENA, boosting conversion efficiency by 52%.  

- Focused on households with $65k+ income and frequent online apparel purchases.  

Reactivation

Identified 1.8M inactive users (4+ months) and served CTV ads with:
  
- Personalized Offers: “We Miss You! 30% Off Your Favorite Category” (e.g., swimwear for past beachwear buyers).
  
- Scarcity Triggers: “Back-in-Stock Alerts” for items left in carts.  

02//
Dynamic Creative Optimization (DCO)   

1:1 Personalization:

Auto-generated 15,000+ CTV ad variants weekly, including:  

Brazil:

Portuguese voiceovers for carnival sequin dresses + real-time pricing in BRL.

MENA:

Modest wear collections promoted during Ramadan with Arabic subtitles.  

After CTV exposure, users received mobile push notifications with abandoned cart reminders + location-based offers for nearby pop-up stores.

Geo-tailored messaging:  

US: “3-Hour Flash Sale – 5 Pieces Under $50!” EU: “Free Shipping Over €75!”

Interactive Ads:

QR codes for app downloads + voice CTAs (“Say ‘Shop Now’ to unlock 20% off”). 

03//
Prime Content Placements  

Ads aired during Euphoria, Coachella live streams, and Paris Fashion Week coverage, capturing audiences in “discovery mode.”

Contextual Alignment:

Ads ran only alongside lifestyle/reality TV content (e.g., Next in Fashion), avoiding controversial topics.    

04//
