It's official: SendGrid makes moves toward an IPO

This week, Denver-based SendGrid filed an S-1 registration statement with the SEC relating to the proposed initial public offering of its common stock. The Techstars grad, which delivers cloud-based email services for more than 55,000 customers worldwide, was founded in 2009 and has since grown steadily, opening offices in London, San Francisco and Orange County and expanding to a team of more than 400 employees across markets.
