Case Study: JustWatch doubles trailer ad efficiency and drives rapid growth with Snowplow

How JustWatch delivers highly personalized content and adverts with Snowplow

JustWatch is an AdTech company that helps movie studios and VOD providers advertise trailers and serve personalized streaming recommendations. Their challenge was to quickly build an accurate, cross‑platform understanding of users so they could create highly targeted audience segments and prove their business model—so they turned to Snowplow’s event‑level data platform to collect and control the raw data needed for segmentation and personalization.

Snowplow was implemented in under three weeks, giving JustWatch rich, granular event data to stitch user journeys, run machine‑learning clustering, and power an Audience Builder and anonymous identity service for cross‑channel targeting. Using Snowplow, JustWatch doubled the efficiency of trailer advertising campaigns, delivered campaigns with more than twice the view time and half the cost per trailer‑watched versus industry benchmarks, built over 50 million anonymized profiles, and scaled rapidly to international growth and profitability.
