When entrepreneurs pitch their companies, they focus on a variety of things. Some make dazzling PowerPoints. Some make sure to include a nice graph predicting "hockey stick" growth. Some feature their team, their team's experience. Some actually do feature their product.
But few demonstrate it with quite the skill and success of Twilio's Developer Evangelist John Britton. Twilio helps developers add voice and SMS capabilities to their apps. And sure, you could explain how Twilio works. You can have slides that explain your product's capabilities. Or, as Britton did at a recent New York Tech Meetup, you can just do one better and code a demo live in front of your audience.
For those who find themselves making a lot of pitches, this video is well worth watching.
