What they did
Avoid fully AI-generated ads (e.g. Veo 3 generating person, voice and music end to end) because quality isn't fully convincing, fake testimonials break FTC rules, and consumers react badly when they detect AI. Instead shoot real people, then use ElevenLabs to translate one spokesperson into ~30 languages and Suno to layer multiple background tracks on one 30-second YouTube/TikTok ad to test which performs best.
In their words
Sub Club by RevenueCat · 12 AI Growth Lessons for Subscription Apps – Phil Carter, Elemental Growth“And so what I've advised my clients is be very, very careful about going the wholesale AI route and using a tool like VO3.”
“layers on ElevenLabs technology so that you can take one spokesperson and translate their message into 30 different languages using AI or take one 30-second ad unit on YouTube or TikTok and then use Suno to layer in multiple different background music tracks and see which one performs best.”
