The revamp of Euro RSCG Contact (Thailand) follows the opening of the Singapore office last year.
Euro RSCG Contact (Thailand) general manager Neil Holt said offices in Australia, Japan, Taiwan and Indonesia would follow in the next few months.
Euro RSCG Contact was formally known as Direct Impact in Thailand.
In 1999, Euro RSCG bought Direct Impact, which had been operating independently for seven years.
"The company is already up and running. All we've done is change the name and refocused business, said Holt, who has been at Euro RSCG Contact for 15 months.
Holt, who had previously worked with OgilvyOne and Euro in Sydney and at numerous banks around the world, added that Euro RSCG Contact, which will employ 20 staff, was unique because it had created its own software, Star Contact.
