Ixigo, one of the key online travel agencies (OTA) in the market, has maintained a low profile but ensured a slow yet steady growth over the years. The portal, which has been in the news after filing a Rs 1,600-crore DRHP in August this year, has come a long way since being bootstrapped for the first five years of existence. The IPO will help it gain wider capital pools, and nullify the possibility of liquidity constraints in the future. If cleared by SEBI, it will be the fourth Indian company of its kind to become public.
