Zachary Irwin is the co-founder and CEO of Downstream, a Dallas-based marketplace that lets contractors book equipment rentals, dumpsters, portable toilets, and site services with a few taps - the way you might order a pizza. Started in 2022 as 'Trash Gurus' and rebuilt into an AI-driven procurement platform with 100,000+ listings, Downstream raised an $8M Series A in November 2025 co-led by Brick & Mortar Ventures and Moneta Ventures. Irwin came to construction's least glamorous corner from an unlikely place: years as a healthcare-software (Epic) consultant building oncology and pharmacy systems across 22 states.
