Great question, I was in a similar place in 2014. Since then we've increased focus all efforts to one medium, G2 Crowd. In 2015 we added over 85+ reviews and was voted Top SaaS Customer Experience this Spring! We had amazing company: Google, Slack & Hubspot, were also ranked.

It's an ask at the right time, if the feedback is so great most clients are happy to help. I'd love to share more, email or call!
