Abstract
This study investigates the impact of technical feasibility and operational feasibility on IT startup sustainability, with innovation capability serving as a mediating variable. As digital transformation accelerates, IT startups face intense market competition and high failure rates, making sustainability a critical strategic priority. Technical feasibility reflects the readiness of technological infrastructure, system reliability, and technical expertise, whereas operational feasibility represents the effectiveness of workflows, resource utilization, and organizational processes. Using a quantitative approach and SEM-PLS analysis of data collected from 330 employees working in IT startups across major Indonesian cities, this study examines both the direct and indirect relationships among the variables. The results indicate that technical feasibility significantly enhances innovation capability and directly contributes to startup sustainability. Operational feasibility also exerts a significant influence, primarily by improving organizational efficiency that supports innovation activities. Innovation capability demonstrates the strongest effect on sustainability, highlighting its role as a key driver of long-term competitive advantage. The mediation analysis confirms that innovation capability effectively transmits the effects of both feasibility dimensions to sustainability, thereby strengthening their overall impact. These findings contribute to the theoretical understanding of entrepreneurship and information systems while providing practical implications for founders, incubators, and policymakers seeking to enhance the long-term survival and competitiveness of IT startups.
