They may never get funded, and if you stop because of them well you just wasted time you could have been spending polishing your product. Polish your branding. Continue working on it. You can't avoid someone coming up with a clone product, but you can create a better product. Chances are a person who clones an idea is in for a easy buck and will not put the necessary time and effort to produce a high quality product. They will not put the energy into customer service that you will. Make sure your customers know that you stand by your product, and that you will be available to them long after the product has shipped.
