SAN FRANCISCO, United States (AFP) — Facebook yesterday announced it is buying a start-up specialising in helping businesses interact with customers online.

The acquisition of five-year-old Kustomer comes as the leading social network continues to weave e-commerce into offerings, particularly its WhatsApp and Messenger messaging services.

More than 175 million people contact businesses via WhatsApp daily, and the number is growing, according to WhatsApp chief operating officer Matt Idema and Facebookvice-president of business products Dan Levy.

“With our complementary capabilities, we will be able to help more people benefit from customer service that is faster, richer and available whenever and however they need it — via phone, e-mail, text, web chat or messaging,” Kustomer chief executive Brad Birnbaum said of uniting with Facebook.

“In particular, we look forward to enhancing the messaging experience which is one of the fastest-growing ways for people and businesses to engage.”

Kustomer, which is based in New York, will continue to service its existing clients after co-founders Birnbaum and Jeremy Suriel and the rest of the start-up’s team become part of Facebook, according to the companies.

The Kustomer platform provides software tools to help business representatives better tend to customer queries or concerns.

Facebook will provide resources for Kustomer to innovate and grow, according to Idema and Levy.

Financial terms of the deal were not disclosed, and it needs to be approved by regulators.
