About us

Mobile-obsessed technologists

We're technologists who are passionate about the mobile web. Cloud Four started when, many years ago, our initial team of four noticed something was changing in our world: connected, portable, always-on devices were becoming mainstream.

We left behind our traditional web jobs and came together in 2007 to form Cloud Four, a Portland, Oregon based company laser focused on mobile web technology. It was a good bet to make: within a year we saw products like the first iPhone transform the mobile world.

We've taken on dozens of web projects, founded a local organization, spoken at innumerable conferences and workshops, wrote the book on mobile web development, and most recently organized a conference about Responsive Web Design.

We've also added staff, so we should more appropriately be called Cloud Nine, but hey, we had already printed up a bunch of business cards.

Here at Cloud Four, we live, breathe, and dream the mobile web. If you're ready to engage with us about your mobile project, please drop us a line!

Jason Grigsby (@grigs)

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. But WAP was crap so he headed back to the desktop web for several years.

Now Jason spends far too much time thinking about mobile. He founded Mobile Portland a non-profit organization dedicated to educating, promoting and supporting Portland’s mobile community. He co-authored Head First Mobile Web. He is frequently asked to speak about mobile technology and strategy.

Aileen Jeffries

The front-endiest of the folks at Cloud Four, Aileen spends much of her time digging around in CSS, shaking her head at browser incongruities and feeling badly about her umask settings. Notable recent achievements include reaching the "acceptance" stage of mourning the death of pixel perfection.

Pro: Tomato red, inset box shadows, browsers that support rgba background colors, Portland
Anti: devices with browsers that only display one or two fonts (looking at you Galaxy S, Kindle Fire and Windows Mobile!)
Secret Shame: preferring the lowercase t in Arial over Helvetica

John Keith

John really likes making well crafted, high performance, usable web services. Good thing, since he's been doing it for more than fifteen years. He's less enthusiastic about exquisite design at the expense of beautiful functionality, but appreciates great design when he sees it. John is a co-founder of several companies - Kavi, Cloud Four, and Lucid Meetings - and is fortunate to have worked with many, many people who are much smarter than him. Get to know him via @jtkeith2.

Nicole Mors
