Verve

They ran advertising on my app, saying they would increase my revenue. I saw ads but when it came time to cut me a check, they kept pushing it off, delaying thousands in payments. I asked about it each month and finally when I threatened to sue, they began paying, although it was a year after the ads ran. I ended up dropping them after I got my money. If you want a good ad partner, Verve definitely is not it!
