Announcing 2022 Change Accelerator Participants

UpStart is proud to announce the 28 professionals accepted into the two North American cohorts of the 2022 Change Accelerator program.

UpStart’s Change Accelerator equips intrapreneurs – the bold leaders making meaningful change within our community’s Jewish institutions – to employ an entrepreneur’s mindset, change course quickly, and develop creative solutions to meet the current moment. Over the next 9 months, these leaders will learn the skills and tools they need to meet their communities’ rapidly evolving needs, and gain a community of practice with which to brainstorm, take their initiatives to the next level, and create the Jewish community of the future.

This year, our Change Accelerator includes leaders from communities, large and small, across North America. Cohorts will focus on emerging challenges and trends in Jewish life:

The Bold Visions cohort will focus on reimagining the systems and structures that allow our organizations to thrive in a changing world. They will weave visionary thinking, strong cultural practices, and strategic innovation to achieve a brighter and more sustainable future.

The Dynamic Partnerships cohort will focus on exploring new ways to meet community needs and grow organizational involvement. They will deepen stakeholder engagement, invest in transformational relationships, and broaden their impact to achieve the promise of a more just, vibrant, and inclusive Jewish community.
