Myke Connolly, known to some as Mr. Stinky Cakes, is a serial entrepreneur who has always understood — and always preached — the power of marketing. His latest venture is a business that brings that message to light, figuratively but also quite literally. Stand Out Truck has now attracted clients ranging from parents of high-school graduates to the local shop to President Biden — or at least one of his marketing teams. The goal is to make this a national brand, and he’s well down that road.
