Who is Charles Vanderhoff?
Vandersoft occupies a narrow, technical niche by digitizing specific, high-intensity strength training methodologies that are typically managed via manual spreadsheets. Their moat is built on domain-specific utility—integrating complex formulas like 1RM calculations and military fitness standards—which creates high switching costs for powerlifters who rely on these specific workflows.
