The best way to stand out on social media as an entrepreneur is to always offer value. Instead of constantly pushing your business, be a good listener and find out what the needs of others are. Once you do that, you can then start offering suggestions, building that relationship with them.
I would also encourage you to be positive. People flock to positive activity - no one likes negativity, it just brings you down.
To end with, just be you! You are unique! Fill our your profile so others can learn more about you. Be friendly and be social!
