Take care of your existing customer.
Far too many startups (an even well establlished businesses) are too busy chasing new customers that they forget to realize their existing customer base is part of the path to further development of the business. Going further down the road, some who do realize that, seem to be lacking the means of communication. You probably do not need us to remind you, that your customers are the ones who have already decided to do business with you. Depending on the outcome of the business they will either turn up to be you embassadors or your archfoe. We believe most businesses prefer the former!
