Amit Kumar Agarwal, Co-founder and CEO of Bengaluru-based home-rental startup NoBroker, revealed that 'broker mafia' attacked the startup in 2015. Around 50-60 local brokers and hooligans stormed the Bengaluru office and threatened and hit employees. "We had to vacate the office almost overnight and we were not sure where we would go or find an alternate office space," Amit recalled.
