If you already have a small base ASK them to spread the word to their network. Be clear in your ask: do you want them to post on a specific social platform? Specifically send referrals? Whatever it is make it worth their while. Swag, gift card, etc. Let me know if I can help further. - KK

Great question, I was in a similar place in 2014. Since then we've increased focus all efforts to one medium, G2 Crowd.
