The story begins:

NEW DELHI— Facebook Inc. is hiring a high-profile technology executive with expertise in Silicon Valley and India to help develop strategies for its Messenger app, an increasingly important platform for the social-media company.

Anand Chandrasekaran, a former senior executive at Yahoo Inc., will assume a global leadership role working on strategies and partnerships for Facebook’s billion-user-strong texting service, said people familiar with the situation.

It wasn’t immediately clear whether Mr. Chandrasekaran would be based in the U.S. or India.

An announcement could be made as soon as Tuesday, one of the people said.

A Facebook spokeswoman confirmed the hire, but didn’t add anything further.

After working at Yahoo, Mr. Chandrasekaran served as chief product officer at Bharti Airtel Ltd., India’s largest cellular company, where he launched Airtel’s mobile application and a popular music-streaming app.

Last year, he joined New Delhi-based Snapdeal, one of India’s major e-commerce startups, as chief product officer. He departed the company in recent months.

With global users increasingly flocking to messaging platforms such as Facebook’s own WhatsApp and Chinese internet company Tencent Holdings Ltd.’s WeChat, the Menlo Park, Calif., company is eager to transform Messenger into a hub for activities such as e-commerce.

In April, Facebook emphasized its focus on the app at its annual F8 conference in San Francisco, showing developers how to create so-called chatbots for the service. These automated services can interact with consumers in real time to answer questions about the prices of goods, for example.
