Pivoting from Vista-based software to helping Vista contractors adopt AI.
Our story
Our team has years of construction industry experience in both operations and finance. That experience, coupled with a passion for software programming, led to the products we built for existing Viewpoint Vista customers — integrated with Viewpoint through the User-Database module.
We are now pivoting from Vista-based software to helping Vista contractors adopt AI. The foundation is the one we built on before: enterprise systems designed inside the Viewpoint database, with a construction company’s departments, data and reporting responsibilities understood from the inside rather than from a diagram.
Our vision
Adopting AI takes structure. Your people do the work; we provide infrastructure and direction. What we are working toward is a construction company where AI processes workloads consistently across every department — operations, safety and QC, HR, finance and accounting — under one set of standards, with the organization’s own structure driving how that work is coordinated.
That is what orgSTACK™, aiASSEMBLY™ and guardSTACK™ are for: a communication and orchestration layer built on your organizational chart, a standard method for identifying and generating the workflows a company actually runs on, and one centrally managed set of AI operating standards governing all of it.
We’re committed to AI in construction, and we’re still mapping where it goes. We’d rather say so than pretend otherwise.
