Company behind the Scaled Agile Framework (SAFe), founded by dean-leffingwell. SAFe is the most widely adopted enterprise agile framework and incorporates several of Reinertsen's concepts, most notably weighted-shortest-job-first for backlog prioritization and cost-of-delay as an economic input. SAFe's adoption brought Reinertsen's ideas to a mass enterprise audience, though Reinertsen's original formulations are more nuanced than SAFe's standardized implementations.
