Zomato uses Kotlin to write safer, more concise code
Kotlin helped Zomato reduce the number of lines of code in their app significantly, and it has also helped them find important defects in their app at compile time.

Kotlin is a free and open source project under the Apache 2.0 license. The code for the project is developed openly on GitHub primarily by the team employed at JetBrains, with contributions from Google and others. Our choice of Kotlin reaffirms our commitment to an open developer ecosystem as we evolve and grow the Android platform, and we are excited to see the language evolve.
