"As part of the deal, tbh's four co-creators - Bier, Erik Hazzard, Kyle Zaragoza and Nicolas Ducdodon - will join Facebook's Menlo Park headquarters while continuing to grow their app", the report added.
Billed as "the only anonymous app with positive vibes", the app lets users create anonymous polls in which friends can participate. Poll winners receive the poll results as compliments, consistent with the app's strapline: "See who likes you".
TBH's sudden rise was enough to grab Facebook's attention (and money).
The tbh team wrote in an announcement post that "When we met with Facebook, we realised that we shared numerous same core values about connecting people through positive interactions".More news: Google Maps pulls cupcake calorie counter after backlash

Meanwhile, Facebook would not provide any more details about the deal, but the firm is clearly eager to snap up the next big thing in its infancy, save it become another competitor like Snapchat.
However, one expert commented that Facebook keeps a close eye over new companies and is willing to pay a premium to buy them rather than risk them developing into a threat. In a way tbh prevents people from writing spiteful comments and cyberbullying.
By joining Facebook, tbh's leadership team believes it can reach more people with their message of emotional care: "We were compelled by the ways they could help us realize tbh's vision and bring it to more people".
