We are in the consumer-social space (http://boothchat.com) so we need to go out in the wild and find our customers. I'll talk about the first 2-3 weeks of starting up.

At the very beginning you'll need to do direct "sales". Apart from any ongoing efforts to attract press, SEO, SEM, etc, at the beginning you'll have to go out there and beg.

Locate your target audience and create campaigns. These campaigns should create you leads, which you'll have to turn into accounts and then customers... I'm talking like a salesperson here because the principle is the same. Were i mention 'accounts' imagine visitors to your website, where i mention 'customers' imagine those visitors converting to users.

E.g. specific search for relevant to your startup keywords on Twitter. Then engage with these users both from your personal and company twitter account. Never "sell" directly, rather try to get into the conversation.

Do that in a systematic way for a couple of weeks and soon you'll have your first hundred users. Of course this method does not scale, but by the time you're done with it hopefully your other efforts (press, SEO, etc) will start to kick in and you'll move to a whole new game...
