tubics

With tubics, you get everything you need to produce relevant video content with certainty, ultimately optimizing reach, views, and watch time. With smartphones as the swiss army knife of the modern consumer and the consumerization of the enterprise, purchasing decisions on all levels and in all verticals are heavily influenced by the most relevant video content. Today video content can be distributed to almost anyone and can be produced by almost anyone because of digital. Never before was a video so dominant. Most video content produced is simply based either on expert opinion or gut feeling. It is nearly impossible to tell which video will be a success accurately. That leads to wasted production and media budgets because of little reach, as well as disappointed audiences and hurt the brand reputation, as companies have to resort to paid views to reach their audience.
