You’ve got a well-developed brand story and a killer PR launch plan. You know how you stack up to the competition and have a PR budget. Now, it’s time to get people excited about your brand. This post is the fifth and final post in our series about the five things you must do before your startup launches.

Even if you’re still in stealth mode, there are many things you can do to start building anticipate in advance of your launch. Here are 15 suggestions:

1. Make your service invite-only. The exclusivity will make your customers feel extra special, and it will have everyone else clamoring for an invitation.
2. Start a blog long before you’re ready to launch, and regularly post high-quality, sharable content.
3. Create a Pinterest board and fill it with tantalizing photos related to your brand story.
4. Send a series of teaser emails to key journalists and analysts in your field (for more on how to write a pitch email, see The Anatomy of a Pitch Email).
5. Build a beautiful “Under Construction” web page and direct people to it.
6. Tweet. Do it often.
7. Leverage your colleagues, friends, and family to spread the word for you (see How to Turn Your Colleagues into Influencers).
8. Hold a pre-launch party at a trendy venue.
9. Join LinkedIn groups that are relevant to your industry and add thought-provoking comments to the conversation.
10. If you’re selling a product or service, offer fewer items for sale than anticipated demand. When you’ve sold out, make a lot of noise about it.
11. Hire people to protest outside a major industry event. It will get everyone wondering what the fuss is about.
12. Host a dinner for an exclusive group of journalists at the best restaurant in town. Don’t tell them more than you have to.
13. Send handwritten letters or memorable gifts to influencers you want to notice you.
14. Start a movement on Facebook related to a problem that your business solves. Promote it with Facebook ads and the help of your network.
15. Write an ebook and release it before your company launches.
