Regular listeners might remember that I interviewed the guys at Send Grid last year. SendGrid was Founded in 2009, after graduating from the TechStars program, and developed an industry-disrupting, cloud-based email service to solve the challenges of reliably delivering emails on behalf of growing companies.

SendGrid is a leading digital communication platform, enabling businesses to engage with their customers via email reliably, effectively and at scale. A leader in email deliverability, SendGrid has processed over 40 billion emails each month for internet and mobile-based customers as well as more traditional enterprises.

I catch up with SendGrid CEO, Sameer Dholakia in London and chat about becoming the first startup accelerator graduate to ever go public (with DropBox following shortly thereafter). We also discuss the story behind SendGrid becoming a leader in email deliverability that processes over 40 billion emails each month for internet and mobile-based customers as well as more traditional enterprises.
