The stars aligned. 3 aspiring professional women and 1 incredible horse, American Pharoah. GSS traces its roots back to the 2015 Breeders’ Cup World Championships, when all eyes focused on American Pharoah, the first and only horse to win the Triple Crown and the Breeders’ Cup Classic. Shortly after witnessing this historic event, visionaries Molly and Shona founded Grand Slam Social. With a shared vision of redefining marketing excellence and a commitment to delivering tangible results, Molly and Shona set out to create a unique agency that would stand out in a crowded market.


From the outset, GSS focused on cultivating strong relationships with clients, understanding their needs, and crafting bespoke marketing strategies that align with their business goals. This client-centric approach quickly gained recognition, attracting legacy clients such as Breeders' Cup, Fasig-Tipton and Del Mar Thoroughbred Club. These partnerships not only validated GSS's expertise but also propelled the agency into the spotlight as a trusted ally in the equestrian industry.


When Molly and Shona stepped away to pursue other ventures, their first full-time employee, Kaitlin, was named as COO/Head of Operations. GSS continued to flourish, expanding its service offerings to encompass a wide range of marketing solutions, from social media management and content creation to branding and event activations and Kaitlin drove the rebranding to GSS, The Marketing Agency.


The agency's commitment to innovation and staying ahead of industry trends ensured that clients received cutting-edge strategies tailored to their unique challenges and opportunities.Today, led by CEO and Managing Partner, Kaitlin, GSS is a powerhouse agency known for its inspired ideas and exceptional results.


Looking ahead, GSS, The Marketing Agency is poised for even greater success. With a solid foundation built on years of experience, a roster of esteemed clients, and a team of dedicated professionals, the agency is ready to embrace new challenges and opportunities in the ever-changing marketing landscape. As GSS embarks on its next chapter, the focus remains on delivering unparalleled value, fostering innovation, and continuing to be a driving force in the equestrian industry and beyond.
