Depends if you're B2B, or B2C. For both, though, giving some incentive to be an "early adopter" is a must. My company is SaaS; to get some initial momentum, we offered early adopters their first year at a discounted rate, additional functionality at a fraction of the normal price, and an account credit if they connect us to another customer that ends up working with us. We actually still do the latter; nothing is better than having your customers be your evangelists.
