Indian tech unicorns such as Paytm, Zomato, and PB Fintech have rebounded from a global selloff last year and have gained between 28% to 69% this year, adding over $4.7 billion in market value. These companies have focused more on profitability, leading them to exit businesses that showed little promise and cut costs. Even though the global concerns remain, the sector has regained interest as pandemic-safe investments due to its potential in emerging technologies such as artificial intelligence. Despite their gains this year, some shares still trade below their IPO price.
