Many retained executive search firms offer 6 months to 1 year as their standard replacement guarantee. The issue with that is typically the MBOs and/or role objectives have longer timelines (as in 2 to 3 years) that are often the basis for bonuses and stock options and/or equity. NextGen Global Executive Search leads the recruitment industry with a 2-to-4 year replacement guarantee. This is also the reason why our retention rates are longer at 94% of our placements with the client at the at the 5-year hire anniversary date. That means they are excelling and often have been promoted because they have added laudable intellectual property, strategic direction, or increased revenues and market share.
