Paytm founder Vijay Shekhar Sharma called Google "judge, jury and executioner" after his app was temporarily removed from the Android app store last month for a policy violation. On Thursday, he kicked off his company's "Mini App Developer Conference" by calling Google a "toll collector".
Google, whose Android operating system powers nearly 99% of India's roughly 500 million smartphones, has faced criticism from several startups in the country over a move to enforce its global policy more strictly and charge a 30% commission for in-app purchases.
That criticism led the U.S. tech giant this week to defer by six months its deadline for Indian companies to comply with the new billing system.
Paytm's Sharma is trying to use the discontent to attract business to his newly launched mini app store, which is hosted within the Paytm app. He has vowed not charge domestic app developers any fees.
"Neither a company from the East, nor a company from the West, if someone will rule India it will be an Indian company," Sharma said in the virtual conference.
Google did not immediately respond to a request for comment.
A mini application is typically hosted within a bigger app and the user experience may not be as seamless as a standalone app, but it can save app developers the time and money involved in building more complex apps.
Paytm's mini app store will allow "app developers to, for good, forget about going through somebody else's kingdom or roads," Sharma said.
Paytm, also backed by Japan's SoftBank and Warren Buffett's Berkshire Hathaway, will create a 100 million rupee (1.06 million pounds) fund for India's mini app developers, Sharma added.
For Google, the face-off against Paytm and other Indian app startups creates a new problem in one of its top growth markets, where it has committed to spend around $10 billion over the next five to seven years through equity investments and tie-ups.
Google also faces four antitrust cases in India, the latest of which alleges the Mountain View, California-based tech giant abused its Android operating system's dominant position to garner an unfair advantage in the smart TV market.
Google has denied any wrongdoing.
"A number of app stores will have to come in this country and co-exist," Paytm's Sharma told Reuters.
