Senior leaders play an essential role in facilitating knowledge creation processes and driving firms' innovation performance. However, little is known about the underlying relational mechanisms by which CEOs help build knowledge integration capability and drive firm innovation. We developed and tested a conceptual model about the ways in which CEOs shape a context conducive for knowledge creation processes and drive multiple innovation performance. A field, survey‐based, study among small‐ to medium‐sized technological ventures (SMVs) showed that CEO visionary innovation leadership (manifested by both vision for innovation and enactment of the vision through specific leadership behaviors) was positively related to a context of connectivity. Connectivity was related to firm knowledge integration capacity, which in turn resulted in enhanced firm innovation (new product quality, development speed, and product innovation). The findings also indicate direct links between CEO visionary innovation leadership and knowledge integration, and between connectivity and product innovation. Implications for theory and practice are discussed.
