Our take
In recent years, the commercial construction industry has faced more volatility than ever. Construction costs are on the increase, there are constraints on supply chains, material and labor shortages have become more common; and manual ordering processes hold companies further back by being timely and prone to error. Kojo, founded in 2018, supplies software for material management that brings supply chains to a single platform, helping to keep construction companies moving efficiently.
Kojo was founded in response to the archaic pen-and-paper material supply chain that was holding back housing construction even in otherwise innovative neighborhoods. Its software brings field, office, warehouse and vendor teams together to manage materials needed from takeoff to closeout, and to ensure visibility across general and specific stock to avoid unnecessary wait times for workers. The company is the leading materials management platform for the construction industry, supplying first-of-its-kind technology.
Named as one of Inc.'s Best in Business for software in 2024, Kojo has received substantial investment and has an impressive list of customers. Funds are cited to go towards continuing to build the platform and add new products that help contractors save money and time. These have included 2025's AI tool to help combat the rise in material costs for contractors.
