Downstream is a marketplace platform transforming the waste and construction industries from the ground up. We're on a mission to bring simplicity, transparency, and sustainability to two of the most essential — but often overlooked — sectors of our economy.

We make it easy for contractors, builders, and businesses to find and book critical services like dumpster rentals, hauling, site services, and equipment — all in a few clicks. No endless calls, no confusing pricing, no waiting around. Our platform connects customers with vetted, reliable providers so they can get what they need, when they need it.

We're not just about convenience — we're about impact. By streamlining logistics and digitizing the supply chain, we're helping reduce waste, cut emissions, and build a cleaner, more sustainable future. Let's build better, together.
