Want to captivate an audience like Obama? There's an app for that

Like it or loathe it, being an entrepreneur means a lot of talking. Whether it's chatting at networking events, pitching to investors, selling your product to customers or explaining it to journalists, talking is a big part of what you sign up for. "Talking is the way you represent your brand; it's the way you build credibility in what you're doing," says Danish Dhamani, co-founder of Orai, an app that claims to make you a better public speaker. But talking – or rather, public speaking – wasn't something that came naturally to either Dhamani or business partner Paritosh Gupta. The pair met in their first year at university in Philadelphia, where they are still based.
