Reward them extremely well when they over perform. One sales person can easily create more ARR than 3 or 4 average ones. Make sure you pay them accordingly, and you can save yourself a lot of headaches and wasted hires.
Agreed. In most cases, you can afford to not hire the absolute best tech talent (assuming you aren't trying to break ground on new tech frontiers), but you should get the best sales talent possible, almost always.
Do you have any tips?
