There's an old saying from east London: “Where there's muck, there's brass.” Essentially, what this means is that the management of the dirtier side of life is invariably an opportunity for a decent business. Sewers are a big business. There are a million miles of them beneath our feet in the US, and about 300 million of them need to be inspected and cleaned every year. A serious undertaking. Matt Rosenthal, along with his Co-founder Billy Gilmartin, is building SewerAI in order to massively improve the process, efficiency, and accuracy of completing these inspections, and much more besides. As you will hear, he thinks as clearly about the fundamental job of an entrepreneur and leader as anyone we work with, and his pathway to building SewerAI was as entrepreneurial, honest, and compelling as any you will hear. Fitbit's loss was US sewer infrastructure’s gain. Please enjoy my conversation with Matt Rosenthal.
