Share it all. Complete transparency. Show them the cash flow. At your small size you will benefit from the additional trust and alignment this will bring. You may find yourself delighted in finding that many of your team can see and solve problems that you may have missed. You can be super secretive to combat the BigCo mentality like Apple when you have the first class problem of being a BigCo.
I advocate balancing full transparency (I certainly don't mean to hide any info!) with a culture that can create a time and place for conversations that might go beyond today's work.
