With population growth drastically rising, so are the number of adults diagnosed with Alzheimer’s. Donations for research are desperately needed, but a growing younger demographic has trouble understanding the disease.

One of the devastating symptoms of Alzheimer’s is memory loss, with the resulting confusion turning loved ones into strangers. The Branch Out Neurological Foundation wanted a way to raise awareness and donations by having people experience the ill-effects of Alzheimer’s, first-hand. The agency, Rethink, created custom phone cards and distributed them to people on Family Day. These cards gave people the ability to call someone anywhere in the world for free. What they didn’t realize was that the call routed through a hacked VoIP server which modulated their voice to make the caller sound unrecognizable. After the call ended, they received a pre-programmed text explaining why the listener couldn’t recognize them. They were encouraged to visit the Branch Out Neurological Foundation website to learn more about Alzheimer’s research and to donate. With permission, the Foundation used some conversations in 60 second PSA radio spots.

Then the brand took the voice modulation technology to podcasts, which have a massive listenership within younger demographics. Like the phone voices, each host’s voice was modulated to sound unrecognizable. Confused listeners everywhere reacted online to the strange voice claiming to be the one they knew. At the end, the host unmodulated their voice to explain the stunt, the Branch Out Neurological Foundation and the importance of Alzheimer’s research.

Over the course of the campaign, website traffic skyrocketed over 1,100%. First-time donors rose 56%, while donations shot up by 432%, making the untraditional campaign one of the most successful in the foundation’s history.
