Upvotes stopped. What next?

We launched project 2 months ago. Excited,anxious, happy, scared... Everything started nice, it was like a sport match, and we were leading :D Suddenly, everything changed and from #3 we fall bellow first 10, then all the way down. Friends of friend, and their friends exhausted, all wanted to help and upvoted, but now, all the resources i know upvoted. Month ended with 144 Upvotes. Day one it was 124. Two months later, still 144. What next? How do you find people to see your product and upvote it?
