Case Study: OBI Worldphone achieves 40% higher cross-screen CTR and 62% higher phone/tablet CTR with Appier CrossX

Obi Worldphone - Customer Case Study

Obi Worldphone, founded by former Apple CEO John Sculley, designs affordable smartphones and launched the SF1 to boost awareness in Vietnam. Obi’s challenge was to reach users likely to buy across every device they own while keeping costs down by optimizing cost per click.

Working with Appier, Obi used CrossX AI to identify high‑intent audiences and their devices, CrossX Remarketing to serve ads on the screens users were most likely to engage with, and CrossX Frequency Capping to avoid ad fatigue. The campaign delivered strong engagement: cross‑screen CTR was 40% higher than single‑screen, and CTR on phones and tablets was 62% higher than other cross‑screen paths.
