Listen Labs


Listen Labs used a minimalist billboard in San Francisco displaying only a string of AI tokens. While cryptic to most viewers, the puzzle was instantly recognizable to the AI engineers the company wanted to reach. Once decoded, the tokens led to a custom coding challenge modeled after the company’s algorithm. The activation sparked widespread discussion across developer communities and tech media, proving how targeted IRL creativity can reach exactly the right audience.

Creative Excellence: Instead of explaining the brand or message, Listen Labs leaned fully into intrigue by displaying only a cryptic string of AI tokens. The unconventional approach transformed a static billboard into an interactive challenge and the first step in the company’s recruiting process, designed specifically to attract highly technical AI engineers.
Client Success: The billboard quickly gained traction after an OpenAI researcher shared it online, sparking widespread discussion across developer networks and social media. The campaign generated major tech press coverage from outlets including VentureBeat, Forbes, and CBS News.
