Babka joins Vibrant from the same role at global IT security company Sophos, where he was working on an IPO, before it was acquired by Apax Partners.
Babka also led NeuStar’s $700m initial public offering and listing on the New York Stock Exchange on June 29, 2005, and $700m follow-on offering in December 2005.
Craig Gooding, chief commercial officer and co-founder of Vibrant, said: "The appointment of a world-class CFO gives us the ability to look into an IPO."
However, he said there were no immediate plans for a public offering, and added that the timing of the appointment is due to the scale of the company, which now boasts revenue of $100m, and its expansion across Europe and the US.
Vibrant, which aligns billions of words on the internet with relevant video, information, tools and advertising, works with clients including Microsoft, Unilever and AT&T.
The company has a network of more than 4,500 premium publishers, and claims to reach more than 170 million unique users per month.
