If you've ever wanted to support a young company beyond pledging money toward its products, it's time to act. After years of waiting, the US has enacted new rules that make it much easier to crowdfund a company through investments. Before, you had to be an accredited investor with some wealth (making over $200,000 per year, or a net worth of over $1 million) to contribute significant money and get a stake. Now, anyone can invest $2,000 or more online and get a say. Companies can't raise more than $1 million per year through this method, but that could frequently be enough to get the ball rolling.
