Brazil's oldest bank finds Gen Z on TikTok.
Banco do Brasil, Brazil's oldest bank, wanted its next generation of account holders. The bank came to Genero to test whether the platform could deliver real performance: new accounts opened by younger customers.
Genero's creative team produced fun, platform-native ads showing how easy the digital account is to open and use. Everything was built to TikTok best practice, and ran as in-feed ads targeting young customers who didn't yet bank with Banco do Brasil.
The campaign hit its target cost per acquisition in the first month. With ongoing creative tuned on early signals, the final CPA landed nearly 30% below target, and around 80% of new account openers were aged 18 to 34. The campaign helped Brazil's oldest bank shift meaningfully younger.
