After a tepid few years of Indian startups stalling public listing plans amid a global tech slowdown and choppy markets, new age firms are now set to make a comeback in the public markets. About 15-20 startup unicorns are expected to launch initial public offerings (IPOs) in the next 12-24 months, senior officials at Kotak Investment Banking said. In fact, companies like Ola Electric, FirstCry and MobiKwik have already filed draft IPO papers with Sebi and will be among the first of the lot to get listed on the bourses this year.
