Faithbox, a subscription service that provides a hand-picked selection of items that are meant to strengthen faith through the month, used Reddit to increase their brand awareness and increase subscriptions. They targeted subreddits that they felt would be receptive to their service, and created copy and a coupon code that they hoped would encourage users to sign up.

While they didn't generate any direct sign-ups, they were pleased in general with the traffic the advertising generated. Again, Reddit's low cost and high user numbers make it an attractive (and wildly underutilized) option for marketers.
