The Revenue Gap
Once a company crosses $10M in revenue, growth rarely slows because of strategy. It slows because hiring cannot keep up with execution. Recruiting and ramping a single BDR often takes four months, leaving pipeline coverage thin while targets stay the same.
Costs continue to pile on during that gap. Salaries and benefits are only part of the expense. Each hire adds roughly $1,500 per month in software licenses, plus the hidden cost of leadership time. Your VP of Sales ends up managing entry-level prospecting instead of driving strategy and deal momentum.
Co-managed Sales Development Staff Augmentation closes that gap, adding execution capacity without long hiring cycles, overhead, or management drag.
