You should be giving out a lot of equity to your employees.
If you compromise and hire someone mediocre you will always regret it.
What you want to do is innovate on your product and your business model, management structure is not where I would try and innovate.
You really want to know your cofounders for a while, ideally years.
You can win with the best product, the best price, or the best experience.
A winning team feels good and keeps winning. A team that hasn't won in a while gets demotivated and keeps losing.
