Since leaving CNBC in February, he has been consulting at the firm and will now be responsible for leading advertising sales to both advertisers and publishers, and opening up new channels for the business as it seeks to scale up globally, according to This Is Open.
Maraviglia joined CNBC in 2008, taking up the post from Liz Jones who left the broadcaster to become managing director of Posterscope's airport media specialist, PSI Advertising.
Joshua Rex, co-founder and chief executive of This Is Open, said: "Paul is a hugely experienced commercial manager, with a broad range of experience and knowledge of the international media sales environment.
"We are delighted he has decided to join the business at this critical stage of our development. The addition of Paul, and the fact that the business has just secured venture capital (VC) funding, will allow us to scale significantly over the next few years."
Prior to his time at CNBC, Maraviglia held the role of managing director of Tartan Films and before that, was managing director for the EMEA region for the publisher McGraw-Hill. He also held the post of vice-president and international publisher for Business Week.
Maraviglia said: "I am passionate about making advertising as transparent as possible, and helping brands efficiently target their customers. Having experienced first hand the shift from traditional advertising to new media, I feel well placed to not only help brands navigate this increasingly fragmented advertising market, but also, critically, to prove a real return on investment."
This Is Open clients include Kia, Nissan, Shell, BP and Castrol, Phillips, Intel, Johnnie Walker, Vodafone McLaren Mercedes, Fox Entertainment, and Lego.
Maraviglia departed CNBC following a merger of the international operations of CNBC in Asia-Pacific and the EMEA regions that kicked off last year and included the departure of Mick Buckley who was president and chief executive for the EMEA region.
At that time, Satpal Brainch was promoted to president, CNBC International.
