Every project that launches on Kickstarter can be found on the Just Launched page of Discover. Your project will also appear in the search results for its corresponding category, subcategory, and location.
Lots of people who come to Kickstarter will browse around and look for projects, but keep in mind that when it comes to finding new backers, getting the word out through your own networks is the most effective. Check out the Promoting your project section of our help center for more information.
