Mariateresa Vacalli is CEO of Bank Cler, a subsidiary of the larger Basler Kantonalbank (BKB), a traditional local incumbent in the German-speaking part of Switzerland. She needs to secure the successful future of Bank Cler and its mobile bank Zak, in an increasingly digitally connected and competitive space. The variety of disruptive business models with a range of online financial services offerings backed by traditional banks, foreign competitors and fintechs poses a complex challenge. After attracting many customers following its launch in 2018, Bank Cler’s mobile-only bank Zak has seen its number of customers stagnating. Having analyzed the business models of other digital banks and the threat of tech giants entering and competing in the Swiss market, Mariateresa needs to choose whether to focus on the existing omnichannel strategy and customer segments or expand internationally.
