You can either try to build a brand or compete in the search market. I'd suggest building a brand. In the beginning it helps to make sure the name doesn't auto correct / suggest a misspelling when you Google it. Make sure it's a word that isn't dominated by another major company as well.

Build out relevant social media pages (Twitter, Facebook, Youtube etc) and with handles the same as your name. A pretty decent example is Grave, a user here, and what he did with Rsultimate (one word). It didn't auto correct, was still relevant/unique, and he made social media pages to help dominate search results for his company.
