Email marketing company SendGrid just made its market debut on the New York Stock Exchange. Shares jumped 12.5% in their first day of trading, opening at $18.55 after pricing at $16 a share. Sameer Dholakia, CEO of SendGrid, joined us on set to explain why email marketing is a promising business to be in right now. Dholakia fills us in on how the company plans to put its new funds to work. He says SendGrid will put the money back into investments in core solutions, use it to expand internationally, and to build its partner channels. The CEO adds that email marketing is a good opportunity because email is the primary means of communication for so many people. SendGrid capitalizes on the trend by sending over a billion emails a day. SendGrid has an impressive list of clients, which includes Uber, Ebay, and Spotify. Dholakia says that one of the company's strengths is that it has such a diverse clientele, with no individual company representing over 2% of revenue.
