Ever since Twitter went public the company has struggled to match the growth expected from its investors. Now it looks like the social network may have partnered with a longtime rival in a bid to increase its user base.

This week a dedicated WhatsApp button began popping up in Twitter’s Android app. Tapping the green icon launches a small window inside the app so you can send a funny or interesting tweet straight to your WhatsApp contacts. The new feature is mainly showing up in India, where the Facebook-owned messaging service is particularly popular.

It’s likely that Twitter sees the addition of a WhatsApp button as a way to push into India’s rapidly modernizing market. Making it easy to share tweets over the service should encourage more people to sign up for a Twitter account, especially once they start receiving links to the site from their friends.

On the other hand, partnering with WhatsApp means giving its parent company Facebook a closer look at Twitter’s own data. Whether that gives the social media giant a greater advantage over the competition is unclear, but it shows how WhatsApp may have been worth the $19 billion spent to acquire it.
