Lon Johnson, CEO of WaterWorks Fund, knows Milwaukee is ahead of Detroit in developing technology for clean drinking water. But he thinks Detroit could overtake other Great Lakes towns by becoming the Capitol for water technology investment capital that can fuel innovation. Johnson, of Detroit and a former chairman of the Michigan Democratic Party, has recently co-founded a Detroit-based online investment platform aimed at crowdsourcing equity capital for water technology projects at WaterWorksFund.com. He recently spoke with Crain's Senior Editor Chad Livengood about his new business initiative on the Detroit Rising podcast.
