What's striking about top-tier tech entrepreneurs is their obsession with operational minutiae. They can recall technical specs, supply chain costs, and manufacturing details without hesitation—it's almost like they've got everything archived in their minds. The common thread? An almost obsessive focus on cost efficiency. They relentlessly hunt for ways to trim expenses across every department, viewing cost optimization as fundamental to scaling operations. This mentality of constant cost-cutting and detailed knowledge retention becomes their competitive edge in building lean, efficient organizations.
