This research aims to examine the factors that influence the intention and use of financial technology, especially digital investment platforms, using the Technology Readiness Index (TRI) and Unified Theory of Acceptance and Use of Technology (UTAUT) models. Data were collected through an online survey using a questionnaire distributed via Google Forms, with a total of 300 respondents. Data analysis was conducted using SmartPLS v.3.2.9, with the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach to test the validity and reliability of the measurement model, as well as the relationship between constructs in the structural model. Based on the results of the hypothesis test, it can be concluded that most of the independent variables have a significant effect on Behavioral Intention (BI).
