About GreenSock

There is a special breed of developer/designer with a passion for building experiences, not just static interfaces. They won't settle for simple rollovers and a few fadeins/fadeouts sprinkled throughout their projects. They sweat the details. For them, success isn’t measured by "does it work?" but rather "is it a joy to use? Does it pleasantly surprise and captivate?" They're students of their craft, pushing the limits and chasing excellence. They’re rarely satisfied with their own work, but that's what makes them good. The screen is their playground.

That special breed is precisely who we aim to serve. Having been in the trenches for over 15 years, we understand the unique challenges that developers face.

One of the most common frustrations we encounter is the lack of reliable, well-crafted, and robust code that could be consistently used across projects. Sure, there were open source options and code snippets on blogs but most of them were either abandoned, inefficient, anemic, obtuse, bloated, or riddled with bugs. The commercial components we saw were largely built for novices, lacking professional-grade flexibility or performance. So we set about the task of crafting the tools we craved. When we shared them with the community, the response was nothing short of astounding.

We’re obsessed with making the tools better and we're committed to supporting the community that has grown to love our tools almost as much as we do.

The Customers

Our Team

Jack Doyle

Founder and Code Connoissuer

An odd mix of designer and developer, Jack transitioned from an award-winning artist into a code-obsessed geek who crafted the GreenSock platform. He is the world’s worst multi-tasker (he can barely walk and chew gum at the same time), but if you give him a challenge or riddle, his one-track (ahem, stubborn) mind locks in and won’t let go until it is solved. He gets a kick out of dreaming up ways to accomplish various advanced feats with JavaScript/HTML/CSS and then delivering tools that make it easy for others. He loves his work and it shows.

Listen to Jack interviewed on the Eggheadio podcast here.

Jack and his Brazilian wife live near Chicago with their 2 sons. He played volleyball for Illinois State University and still enjoys playing despite his aging joints and declining vertical leap. He loves discussing the issues related to what people believe (and why), who Jesus is (or isn’t), and how faith affects our lives inpractical ways. He shared a little bit about his faith journey here.

Carl Schooff

Geek Ambassador

With an uncanny ability to simplify complex concepts and teach them in practical, easy-to-understand ways, Carl keeps his finger on the pulse of the community and helps them make the best use of GreenSock tools. Years of experience as an educator in classroom settings and beyond plus his extensive knowledge of the GreenSock platform make him uniquely qualified to speak at conferences and corporate training events. Unlike many dry, stuffy technical presenters, Carl’s relatable style, sense of humor, and real-world emphasis keep things fun and engaging. Over a decade of serving fortune 500 companies at the top agencies in the world has made him keenly aware of common development challenges.

Carl, his wife, and 2 sons are New York natives (a fact that’s tough to miss when you hear Carl speak). He is a devoted family man and is active in church. He also enjoys fishing and camping, but only in small doses because when he is unplugged from the grid for too long, he quickly slides into depression and withdrawal.
