Upon seeing those words, I realized that's what a lot of media startups are. For example, my companies runs a variety of e-mail newsletters and most of our advertisers are other companies looking to acquire users/customers. We've had advertisers run a single ad with us and pick up 1000 e-mail addresses on their landing pages, etc. That seems quite close to a practical user-acquisition startup even if the intent isn't there.. It does give me some ideas on extra ways to sell the value to potential advertisers though(!) :)
