Without having a lot more detail on what you are doing or who your market is, what worked for my company (B2B software professional services) was getting out in front of potential customers by attending trade shows and conference for my target industries, having a booth when I could afford it, speaking about a particularly interesting use-case, do webinars in conjunction with a partner software company and trade associations.
It is hard to stand out when there are a lot of competitors (with a lot more resources) - specializing by technology, solutions, and industry helps you focus on customers who are potentially overwhelmed with options, too.
