My honest opinion is that this is a more expensive version of SponsoredTweets (which won't fly because they have a mass of users and important value add features, which this is lacking) . Ad.ly also does this but I think they have a pretty high minimum budget. SponsoredTweets also has performance tracking, which advertisers would want. I'm also not clear on what brand means in this context - how is that different from a sponsored tweet?
