Solve Media, a startup that turns CAPTCHA verification systems into ads, says that it's growing quickly. There were more than 1 billion engagements with Solve's Type-In ads last year, the company says. It will exceed that number in the second quarter of 2013 alone, and it should hit 4 billion for all of 2013. Solve also says that it's on-track to bring in $13 million to $16 million in revenue for 2013.
