Change order platform: T&M ticket capture, AI categorization and real-time cost exposure
The point of this database is discovery: tools working in the market that you may not have heard of yet. The incumbents everyone already knows are deliberately excluded. Top section: tools a guest has actually used or that have been covered on the show, with what was said. Below that: the wider radar we track, one line each, so you know it exists before your competitor does.
