What it is: If any startup can prove email is not dead, it's SendGrid. This 7-year-old startup, which makes email marketing and tracking tools, is profitable, expects to generate $100 million in revenue next year, and has signed up over 42,000 paying customers, including some of the largest tech companies like Uber, Airbnb, and Spotify.
Its CEO, Sameer Dholakia, calls SendGrid the "Twilio for email" because of its simple API structure that makes it easy for any company to gain access to its email management platform. The Twilio analogy doesn't stop there — the company could go public in 2017, according to VentureBeat.
