From the beginning, Kroo’s architecture was designed with future scalability in mind, using PostgreSQL as its database and Apache Kafka as the mechanism for message distribution. By embracing an asynchronous infrastructure, Kroo can also independently scale different parts of its system, improving efficiency and responsiveness. After securing its full UK banking license in 2022, Kroo launched its current account. In the next 12 months alone, it secured an impressive 150,000 customers.
