TUNE Leadership Team

Meet Our Leaders

Cynthia Sener, President of Affiliate Marketing Group - Perseus / CSI

Cynthia Sener


President, Affiliate Marketing Group — TUNE | CAKE


As President of Affiliate Marketing, I oversee TUNE and CAKE teams within the Andromeda Group of Constellation Software Inc. (CSI). I was previously with CSI 12 years ago and jumped at the chance to rejoin the team in 2024. Returning, I bring 25 years of digital marketing experience to support the TUNE and CAKE teams and superb products.

Personally, I love the outdoors and cannot get enough camping, sailing, SCUBA diving, and horseback riding. I'm a mom of two teenagers (and a wide variety of pets) and spend my free time as a free taxi to youth groups, community theaters, and Girl Scouts.

Garth Harris


COO, Affiliate Marketing Group — TUNE | CAKE 


As COO of the Affiliate Marketing Group, my focus is to drive growth and adoption through our marketing and product teams while providing excellent customer service within our onboarding and support departments.

I’ve been in the affiliate marketing industry for 15 years. In that time, I’ve held a wide range of roles, from client services manager to senior director of product engineering and, most recently, general manager at CAKE. These experiences have helped me build a deep understanding of our customers and their businesses.

Outside of work, I’m happiest behind a grill or at the beach with my family.

Karen Nugent


VP of Customer Success, Affiliate Marketing Group — TUNE | CAKE


With over 25 years in the performance marketing industry, I currently lead Customer Success at TUNE and CAKE, helping our clients succeed with their programs. I focus on building strong partnerships, empowering our team, and driving strategic outcomes that align with our customers’ evolving needs.

Outside of work, you can usually find me walking my dogs Coco and Benji, painting abstract watercolors, or enjoying good champagne with people I love. I’ve traveled the world, but these days, it’s the simple joys — sunshine, art, and connection — that keep me inspired.

In my role as Finance Manager for TUNE and CAKE, I help align financial strategy with operational goals, supporting decision-making through analysis, modeling, and reporting.

Outside of work, I enjoy spending time outdoors — whether it’s paddleboarding in the summer, cross-country skiing in the winter, or heading out on camping trips with my family. You’ll often find me near the water or on a trail, recharging in nature.
