Nearly 50 Bay Area executives and professionals packed into a gymnasium last week at the state prison in Solano County and lined up, toe to toe, with a row of convicted criminals. For most entrepreneurs, it was a ... a place they had never been. But it was all too familiar for Kenyatta Leal, [who] left San Quentin in 2013 after 19 years behind bars. He was among the first to graduate from the Last Mile Program - a prison initiative [run by Defy Ventures, which is] intended to turn offenders into entrepreneurs. In one exercise, inmates and volunteers were given a prompt and told to step forward or backward depending on whether it applied to them. I have been incarcerated," read Brian Moll, Defy Ventures' executive director for the Bay Area. Every inmate stepped forward. So did a handful of entrepreneurs. One by one, the professionals fell back - all but Leal, who stood alone in his beige suit. "No. No way," said Oakland native Leonard Halfin, 46, who has been incarcerated for 25 years on a second-degree-murder charge. "I can't believe that. I would have never thought he was one of us." This, said Defy founder and chief executive Catherine Hoke, is the most important takeaway: It allows felons to realize that they have potential. Hoke's hope is that participating in programs like Defy's will help inmates formulate plans and sharpen professional skills that can help them become successful.
