The startup world is full of companies where the cash compensation levels are lower than market. This results from the view that the big equity grants people get when they join more than makes up for it. There are a few problems with this point of view. First, the big option grants are usually limited to the first five or ten employees and the big management positions. And second, people can't use options to pay their rent/mortgage, send their kids to school, and go on a summer vacation with the family. Figure out what "market salaries" are for all the positions in your company and always be sure you are paying "market" or ideally above market for your employees. And review your team's compensation regularly and give out raises regularly. This stuff matters a lot. Most everyone is financially motivated at some level and if you don't show an interest in your team's compensation, they won't share an interest in yours (which is tied to the success of your company).
