Corporate venturing serves as a bridge between the innovative potential of startups and the scale and resources of established corporations. Corporate venturing has become an increasingly important mechanism for facilitating sustainability transitions, but its unique attributes in the sustainability context are yet to be adequately addressed. In response, this study seeks to fill this gap by proposing a conceptual framework that emerges from an integrative literature review and qualitative content analysis of 42 scholarly articles. The five primary themes that emerged as essential are innovation, ecosystems, partnerships/networks, transition/transformation, shared value creation, and new business models. The proposed framework contributes to the theoretical conversations around sustainable corporate venturing and offers practical insights for practitioners seeking to integrate corporate strategies with sustainability objectives. This study lays a foundation for future empirical and theoretical research by synthesizing fragmented perspectives and offering structured guidance.
