Jeeze, these guys developed their own database and language to accomplish their objectives. Others might take 10 million in funding, already be focused on the 2nd round, all the while not focused on delivering first.
You have to get there, before you can get there.
Congrats to the BackType team.
Seems the business model pivoted slightly.

anything beyond the last few weeks, you need to pay $100/month.
However, despite their purported effectiveness as engineers, I'm not sure what Backtype is really doing. I generally see them just below an article, in place of comments, with a long list of useless tweets referring to the article (usually of the form "article title - bit.ly/shortened". That's probably not doing them too much good for marketing, unless you think any publicity is good publicity.
Our own product is a marketing intelligence platform; essentially, it provides analytics for social media marketing programs so brands understand what's working, what isn't and how to improve.
