Recruit customers with Craigslist Most of the time, to recruit people who exactly match our target customer, we use Craigslist. We know it sounds crazy, but it works. It’s how we found perfect participants for our tests with Savioke and Blue Bottle Coffee—and dozens of other companies. The secret is to post a generic ad that will attract a broad audience, then link to a screener survey to narrow down to your target customers.
