As a practitioner who focuses connecting domains of the entrepreneurial ecosystem to enable inclusive entrepreneurship,I have read "Who Owns the Ice House" and I believe its strategy to change our "mindset" is paramount. We must be willing to be open, curious, aware, engaged and to explore our common challenges as opportunities to find the avenues that will result in shared-solutions.
I believe the model has the opportunity to scale. In your efforts to scale, please ensure communities of color are engaged at all levels including outreach to further impact access to credit for minorities. A key marketing strategy is word of mouth e.g., trust begets trust, etc. I wish you much success!
