Fair Isaac Launches Sold-Out ``Smarter Decisions'' Conference in Lisbon

Fair Isaac Corporation (NYSE:FIC), the leading provider of
analytics and decision management technology, kicked off its 2007
European InterACT customer conference today in Lisbon, Portugal. More
than 300 business leaders from over 40 countries are attending the
three-day forum, demonstrating the fast-growing demand worldwide for
innovative technologies and strategies that drive smarter decisions.

Fair Isaac's InterACT conference is the world's leading forum on
business analytics, emerging decision management technologies and
their applications. Executives attend InterACT to learn about the
latest strategies for success in critical decision areas including
risk management, fraud protection, customer acquisition and retention,
collections and recovery, and underwriting. They also experience the
newest innovations in predictive analytics and decision automation
technology. InterACT Lisbon is sold out, and attendees represent a
range of industries including financial services, retail,
telecommunications, insurance and technology providers.

"Your presence here - and your use of Fair Isaac technology to
make your very best customer decisions - indicates that you represent
some of the world's most visionary organizations," said Dr. Mark
Greene, Fair Isaac CEO, in his conference-opening keynote address. "As
a partner who is committed to your success, we will continue to
deliver advances in analytics and decision automation that will make
your business faster, safer and more competitive."

Greene, overseeing his first InterACT conference following his
recent appointment as CEO of Fair Isaac, also reinforced Fair Isaac's
commitment to continued innovation, and to creating the standard for
Enterprise Decision Management (EDM), the emerging discipline of
automating and improving decisions. "This company was built on
innovation, starting with the introduction of credit scoring back in
the 1960s, and today we are uniquely qualified to help businesses
around the world bring the most advanced technology to their most
important decision areas," Greene said.

Today's general session also featured a keynote presentation by
Lior Arussy, CEO of Strativity Group, Inc., and a pioneer in the field
of Customer Experience Management. Arussy, who works with Global 2000
organizations and emerging businesses around the world to create
lasting and profitable relationships with customers and employees,
challenged attendees to change the way they approach their customers.

Over the next three days, InterACT participants can choose from
more than 50 sessions, including case studies, research results,
industry panels and strategy discussions on new EDM technologies and
applications. Discussion groups, private consultations and other
conference events provide attendees with opportunities to connect with
