Both my interim and fractional engagements often come about because a CFO didn’t work out. It is arguably difficult to find and properly vet a good CFO, especially for a small business owner.  Many get fooled by smooth-talking candidates who are trying to land a high-paying position above their abilities.  I’ve seen first-hand the damage done to a company by a poor hiring choice, and then months (or years!) of hoping the person will be able to step up their game.  Finally, they face reality and call me.
