India’s Jio Platforms lands $1.5 billion from Vista Equity, marking 3 big investments in 3 weeks

US investment firm Vista Equity is pumping nearly 114 billion rupees ($1.5 billion) into Jio Platforms, the digital technology arm of Indian billionaire Mukesh Ambani’s sprawling conglomerate Reliance Industries.

The investment marks the third marquee cash injection for Ambani’s growing tech empire in less than three weeks. Facebook (FB) invested $5.7 billion in Jio Platforms in late April and private equity firm Silver Lake followed earlier this week with $750 million.

Jio Platforms has several services under its umbrella, including Reliance Jio, the mobile network that has taken India by storm since launching less than four years ago. The carrier has racked up 388 million users, put Ambani’s brother and rival out of business and forced other local operators to merge. Jio Platforms also includes a family of apps where users can stream movies, shop online, send text messages, read news and more.

Vista Equity, which has over $57 billion in capital commitment, invests in software, data and technology companies.

Robert Smith, Vista chairman and CEO, said in a statement that the investment in Jio will help fuel “exponential growth in connectivity across India.”

India is in the midst of an internet boom. It is the world’s second-largest smartphone market and it boasts hundreds of millions of users eager to take part in the growing digital economy.

And there is still plenty of room to grow: Close to 600 million people in India have yet to gain internet access.
