This study examined the influence of Agile Maturity Models (AMMs) on organizational scalability and regulatory compliance adaptability among mid-sized fintech firms in Bengaluru. Grounded in Dynamic Capabilities, Contingency, and Organizational Learning theories, the study aimed to analyze how agile maturity functions as a strategic capability enhancing operational and regulatory outcomes. Using a cross-sectional quantitative design, data were collected from 250 professionals—including project managers, agile coaches, compliance officers, and IT specialists—selected through purposive sampling from fintech organizations employing agile frameworks such as Scrum, Kanban, SAFe, and Hybrid models. Data were gathered via a structured questionnaire comprising demographic, agile maturity, scalability, compliance, adaptability, and organizational characteristics sections, measured on a five-point Likert scale. The tool demonstrated strong reliability and validity (Cronbach’s α ranging from 0.85 to 0.92). Analyses were performed using SPSS (v29) and AMOS (v27), employing descriptive statistics, correlation, multiple regression, and hierarchical regression techniques. Results indicated high agile maturity across firms and revealed significant positive relationships between agile maturity, scalability, and compliance adaptability, with firm size, age, and regulatory exposure moderating these effects. The study concludes that agile maturity enhances both scalability and compliance flexibility, emphasizing its role as a dynamic organizational capability. Ethical clearance was obtained, and informed consent was ensured. Recommendations highlight continuous agile training, leadership commitment, and integrated compliance practices for sustained growth and resilience in the fintech sector
