One of the things I regret not doing when I set up Mixer Lab (since acquired by Twitter) was that I did not gift any stock to my family members when incorporating. When you set up your company, the stock is really cheap (e.g. 0.0001 cents per share or the like). This is your opportunity to give your family, spouse, or other loved ones the equivalent of a tax free gift that could have a major financial impact long term (i.e. the taxes they will need to pay on the gift at this point could be either zero or very low in dollar terms).
