A couple of years ago, Megan Glover was on a coffee date with a friend when the conversation turned to the water crisis in Flint. Glover found herself nodding along. Like a lot of residents of Indianapolis, she was familiar with the topic — Indiana abuts Michigan, and for weeks, it seemed, local media had reported on little else. And yet, as Glover confessed to her friend, a fellow entrepreneur named Chris Baggott, she hadn’t gotten around to testing her own water supply. “I’m not sure where to start,” she said.

“Hey!” Baggott exclaimed. “I think you just stumbled on your next business.”
