Co-founder
In 2000, Jason Grigsby got his first mobile phone. He became obsessed with how the world could be a better place if everyone had access to the world’s information in their pockets. When his soon-to-be-wife met him, he had covered the walls of his apartment with crazy mobile dreams. To this day, he remains baffled that she married him.
Those mobile dreams hit the hard wall of reality: WAP was crap. So Jason went to work on the web until 2007, when the iPhone made it clear the time was right. He joined forces with the three smartest people he knew and started Cloud Four.
He is the author of Progressive Web Apps from A Book Apart and co-author of Head First Mobile Web from O'Reilly. His writing and work helped define the new web standards for responsive images.
He was the founder and president of Mobile Portland, a local nonprofit dedicated to promoting the mobile community where he started the first community device lab. There are now over 150 device labs in the world.
Since co-founding Cloud Four, he has had the good fortune to work on many fantastic projects, including the Obama iPhone App and Walmart's responsive design. Jason is a sought‐after speaker and consultant on web technology and mobile.

I get a bad feeling in the pit of my stomach when I have to tell someone that there is something deeply wrong with their website—especially when I know that it is too late to fix it. I hate that feeling. And I felt it twice recently.
