This study looks into the connections between employee productivity, organizational culture, financial performance, and product innovation in Indonesian fintech companies. A quantitative study was carried out with the data that was gathered from 180 individuals. The data were analyzed using descriptive statistics, model fit evaluation, measurement model assessment, structural model estimation, and mediation analysis. The findings show that financial performance, staff productivity, product innovation, and organizational culture are all positively correlated. Product innovation is strongly influenced by organizational culture, and this has a favorable effect on worker productivity and financial performance. Furthermore, through both staff productivity and product innovation, mediation research demonstrates strong indirect benefits of organizational culture on financial performance. It was discovered that there is no substantial correlation between organizational culture and financial performance. The aforementioned results underscore the need of cultivating an accommodating organizational culture that stimulates creativity and efficiency in order to attain exceptional financial outcomes within the Fintech sector.
