(Sharecast News) - American Express said on Monday that it has agreed to buy TheFork, an online restaurant reservation and management platform, from Tripadvisor for €700m in cash.

Founded in 2007, TheFork connects millions of diners with more than 50,000 restaurants across 11 European countries through its restaurant management, booking and customer engagement platform, alongside a consumer-facing restaurant discovery and reservation app and website.

American Express said the deal - which is expected to close before the end of this year - builds on its broader dining strategy and its acquisitions of digital dining platforms Resy and Tock. "Together, these platforms are expected to expand American Express' dining network to 75,000 bookable venues," it said.

Rafa Marquez, president of international card services at American Express, said: "Dining is one of the most important ways people engage with our brand.

"Over time, the proposed acquisition would help us enrich our differentiated Membership Model by offering Card Members more ways to discover, book and access great restaurants, while helping our partners reach more diners and grow their businesses.

"TheFork has built a successful platform across Europe with strong relationships throughout the restaurant industry that would complement our existing capabilities. We look forward to supporting TheFork's continued growth and building on its success as we strengthen our dining presence across Europe."

Once the deal closes, TheFork will continue to operate under its existing leadership team "while benefiting from the global reach and powerful backing of American Express".
