Terry Whalen, President
@tdwhalenho | LinkedIn

In 1998 Terry became the CEO of Epitonic, a 30-person online music company based in San Francisco, which featured free MP3 downloads, and full album streams—way before Spotify. Epitonic was backed with $3.5 million from CNET and angel investors, and was sold in 2001 to Palm Entertainment. Hanging up his rock star vests, Terry moved to market GoToMyPC software via PPC and other online marketing channels. It soon led to a $225 million acquisition of GoToMyPC by Citrix Systems in 2003. 

Next Terry founded Sum Digital (formerly CPC Search) in 2005. He grew it from experts in PPC Search to a full service digital marketing partner.

Throughout his marketing career, Terry has played a lot of ping-pong and managed search & other online marketing channels that have generated millions of dollars in revenue for his clients.

Terry received his MBA from UC Berkeley's Haas School of Business, and his BA from UC Berkeley in Political Economics. He is certified in Google Search advertising. When not sneaking into SXSW Keynote addresses he can be found speeding through the desert—music blasting.

Kasey Carter, Creative Designer
LinkedIn

Kasey started off signing awnings. Not autographing them but designing signs for them. A hop, skip, and jump later she ended up at Kelby One, an internationally recognized photography and Photoshop training and education company in Tampa Bay. In 2013 she relocated to the San Francisco Bay and started working for Sum Digital.

Having worked as a graphic designer for 12 years and counting, Kasey kills at creating cohesive brand experiences that catch the eye, and coerce the click finger.

Kasey received her BFA from Eastern Kentucky University. When she’s not designing, she’s keeping up with the latest trends in film, music, food, and art, all while avoiding the bearded ones. She prefers people and logos to be clean-shaven.


Maca Gonzalez Costa, Creative Designer
LinkedIn

Maca digitally crossed hemispheres in 2011 to work with Sum Digital. Travelling by high speed internet and Skype she arrived in bits only to discover the food here pales in comparison to home. But the work is good, and as a designer you can always make it better.

Having designed on a different continent before gracing this country, you could say she has received worldwide praise.

Maca earned a degree from the University of Buenos Aires, Argentina (UBA) in Graphic Design. She loves eating clams while watching any Sacha Baron Cohen movie. The best way to reach her is by Skype.
