Duct is a subcontractor management platform that helps general contractors and subcontractors manage their contracts, payments, and paperwork efficiently, filling in the industry's digitalization gap and increasing productivity. The app allows users to sign up for free, send invoices, and get paid with Duct Escrow, as well as manage construction projects on a simple platform. Its creator, Joe Schnetzler, discovered no-code tools like Bubble while researching web development skills and found it superior to traditional coding. He built his startup Pital & Co using Bubble's no-code platform and now plans to add machine learning algorithms and new features to Duct. The app aims to become the go-to construction management platform for small- and medium-sized contractors and subcontractors, with plans for future growth and integration into Bubble's community of builders and entrepreneurs.
