the challenge

Netflix and Doritos wanted a standout, shareable activation for Stranger Things at a time when traditional ad formats were losing attention. The goal was an immersive, on-brand fan experience that worked at large scale without scripting every interaction.

what they built

Casper built a first-of-its-kind interactive voice-AI experience: fans phone a 1980s-style telethon and hold real-time, unscripted conversations with Stranger Things characters. Generative voice AI powers unique character dialogue at scale, capturing fan voice messages along the way.

Casper designed the experience around a phone call: a nostalgic 1980s telethon that fit the show's world. Behind the line, a real-time generative voice-AI system produced unscripted, in-character conversations, so every fan got a different exchange rather than a canned recording. The system stayed on-brand and handled high concurrency, capturing fan voice messages during calls. It launched with zero defects and fielded more than 400,000 calls and 70,000+ voice messages — a novel, shareable activation that turned an ad into a participatory experience.
