Gurugram-based backpacking hostel startup Zostel's Co-founder and CEO Dharamveer Singh Chouhan told YourStory that he began Zostel with $15,000 he won by playing poker. Chouhan said he played poker during his free time at IIM-Calcutta. "Instead of giving a push to my Poker career, I decided to invest that money in building something in the travel industry," he added.
