In Indonesia, a significant portion of the population remains unbanked, with only 23% of adults having their financial needs met adequately. Alternative data offers a solution, enabling fintech companies to gain insights into the financial behaviors of the unbanked population. By leveraging alternative data sources such as mobile phone usage and utility bill payments, fintech firms can develop tailored products and services to address the unique needs of underserved communities. This approach not only drives financial inclusion but also fosters economic growth by expanding access to credit and empowering individuals and small businesses.
