Jobsite Unite, which offers a mobile-first application that helps simplify, streamline and record jobsite communication for construction projects, received $50,000 in equity-free support in Arch Grants 2015 Global Startup Competition. The company, which launched in Des Moines, was one of 11 recipients. Jobsite Unite also will get pro bono services. Arch Grants is a nonprofit that supports startups in St. Louis. Jobsite Unite developed in the now-defunct Startup City incubator in Des Moines, then moved its business development team to St. Louis in February to participate in Capital Innovators, a technology accelerator ranked in the top 10 nationwide.
