Welcome to the public markets, Dropbox (DBX - Get Report) . 

Shares of the data storage firm popped more than 40% on Friday as it debuted on the Nasdaq. They finished the session up 35%. With 500 million plus users, a good revenue growth story to tell and a lack of tech IPOs of late it's no surprise Dropbox was welcomed.

Dropbox chief operating officer Dennis Woodside tells TheStreet the company's growth prospects are solid, despite tough competition from Action Alerts Plus holdings Amazon (AMZN - Get Report) and Alphabet (GOOGL - Get Report) .

"We massive opportunities to scale our business," Woodside said when asked why investors shoudl buy Dropbox's stock. While Dropbox has been slow to get users to pay for its service (11 million paid users per its prospectus), Woodside the company has made progress over time trading people up via new features.
