Zaroth has really good practical advice, but regardless of how much you have in the bank, I'd caution against doing anything too creative with the money. Investors aren't looking to make half a point on their money and they aren't giving you money to invest anywhere else. It's a good idea to make sure your money is secure and you aren't being negligent in your cash management practices, but I don't suspect your board will be impressed if you come up with a fancy scheme to make investment returns on the money they gave you to run your business.
