Criteo Recruits One Hundred Engineers for R&D Team

Criteo to Have the Leading European Centre for Innovation in Advertising Technology

LONDON, February 28, 2011 - Criteo, the global leader in personalised retargeting, has announced it
is recruiting for over one hundred new positions for its research and
development centre in Paris. The substantial investment in engineering will
make it one of the leading centres in Europe for R&D in online advertising.

The announcement comes a month after the company released their 2010
figures which showed momentous growth across Europe, the USA and more
recently Asia.

European technology with global success

The success of Criteo's proprietary technology has already attracted over
1,000 leading Ecommerce clients globally and delivered GBP1.5 billion in
sales last year in the UK alone.

Developed in conjunction with INRIA (The French National Institute for
Research in Computer Science), Criteo's technology revolutionised online
display advertising by enabling real-time optimisation at a scale unmatched
by any other retargeting provider.

With 5 data centres around the world, Criteo responds to more than
100,000 queries per second, taking less than 6 milliseconds to create and
broadcast a personalised advertising banner.

Criteo engenders leadership and innovation

Founded in 2005 by serial entrepreneur Jean-Baptiste Rudelle and Franck
Le Ouay and Romain Niccoli, both former engineers at Microsoft Laboratories
in Redmond (USA), Criteo's global leadership team comprises experts with
proven success in business and technology.

"Criteo is committed to excellence in technology. We only hire the very
best engineers and developers and in return provide an environment that
engenders innovation and creativity," Pascal Gauthier, Chief Operating
Officer, Criteo.

To lead what promises to be the largest centre for online advertising
research and development in Europe, Laurent Metzger, former CTO of Kelkoo and
Julien Simon, former CTO at Pixmania have joined Criteo as joint
vice-presidents of Engineering.

Laurent Metzger began his career at Cap Gemini before joining Kelkoo and
Yahoo where he was appointed CTO in 2007. "Given the explosive growth of the
technical team at Criteo, we are putting in place Agile methods such as Scrum
and Extreme Programming, to accelerate our development cycles," said Laurent
Metzger.

Joining Metzger is Julien Simon whose previous roles include Vice
President Engineering at Digiplug and more recently CTO at Pixmania. "At
Criteo, nothing is impossible. We have carte blanche to improve the
performance and scalability of our applications," Julien Simon said.
