TaxiForSure Co-founder Aprameya Radhakrishna has said "I felt incomplete. We never planned the exit" on his startup's $200-million acquisition by Ola in 2015. Post the deal, Radhakrishna took a sabbatical and made 22 angel investments. Last year, he teamed up with Goodbox Co-founder Mayank Bidwatka and launched peer-to-peer knowledge sharing platform Vokal.
