Denise Karkos

Award-winning marketing exec Denise Karkos has joined SiriusXM as Chief Marketing Officer. The 13-year TD Ameritrade veteran is tasked with helping increase the number of SiriusXM subscribers and Pandora listeners as the now integrated companies draw on synergies and cross-promotion to fuel growth.

Responsible for the brand and digital marketing of both brands, Karkos arrives as Pandora has been working to stem a user exodus in recent months. Monthly Active Users (MAUs) at Pandora were down to 64.9 million in the second quarter, from 71.4 million in the prior year period. Total ad-supported listener hours were 3.49 billion in Q2, sliced from 3.86 billion one year earlier.

She joins SiriusXM from TD Ameritrade, where she was Chief Marketing Officer overseeing brand, advertising, social media, content marketing, corporate communications, marketing analytics, tech and operations. SiriusXM says Karkos was responsible for “redefining the spirit of the brand to drive significant growth and recently led the marketing efforts of the Scottrade acquisition.”

Her work has been acknowledged in the advertising industry trades. Karkos was named 2019 CMO of the Year by Ad Age and was honored with a Brand Genius Award by Adweek.

“Denise is exceptionally innovative and forward-thinking and we are very pleased and excited that she will be leading our marketing efforts as we continue to grow the SiriusXM and Pandora brands,” said SiriusXM’s President, Sales, Marketing and Operations Jennifer Witz, to whom Karkos will report. “She and her team will execute a cohesive marketing strategy to drive brand relevance and consideration through to customer conversion, with a deep focus on digital, social and mobile marketing.”

Before her 13 years at TD Ameritrade and TD Bank, Karkos held a number of roles with agencies, including Digitas and Hill Holiday where she ran media planning and buying.

“I’m excited to join these two great brands and help contribute to their continued success,” said Karkos. “The audio entertainment category has so much momentum, and even more potential. It's a privilege to join the leaders in this space.”
