Abstract: Technology-driven startups on digital platforms face the dual dilemma of high homogeneity competition and high platform dependency. Achieving value innovation in this context is a critical issue. This paper selects Anker, a startup based on the Amazon platform, for an in-depth single-case study to explore the process and mechanism by which it resolves innovation dilemmas and achieves value innovation. The study finds that: during the entry phase, technology-driven startups confront the dilemma of high homogeneity competition. By engaging in "exploitative experiential learning—bricolage resource construction—exploratory product learning—creative resource utilization" with stakeholders through the digital platform, these startups can break through the high homogeneity competition dilemma, achieving product value innovation; during the growth phase, technology-driven startups face the dilemma of high platform dependency. Through entrepreneurial accumulation and "exploitative knowledge learning—accumulative resource construction—exploratory brand learning—integrative resource leveraging" with stakeholders, these startups can overcome the high platform dependency dilemma, achieving brand value innovation. The paper distills a process mechanism model of "innovation dilemma—ambidextrous learning and resource orchestration—innovation outcome," which offers important insights for entrepreneurship based on digital platforms.
