In the so called "Sport of Kings," two young women are proving to be the queens of social media.

“Horse racing, equestrian, social media, they are just made for each other," said Molly McGill, one of the founders of Grand Slam Social.

“It is live; there are always really emotional moments,” said co-founder Shona Rosenblum.

Along with their former business partner, McGill and Rosenblum launched Grand Slam Social shortly after all three worked at the 2015 Breeders’ Cup in Lexington, Ky.

“Grand Slam Social is a boutique social media agency,” Rosenblum said. “We focus on providing services for equestrian businesses.”

The company owes its name to the historic feat known as the Grand Slam, that was accomplished by American Pharoah when he added a Breeders’ Cup Classic victory to his Triple Crown heroics. Soon after, Grand Slam Social signed the Breeders' Cup as its first major client.

“It was everything; we would not be here if it wasn’t for Breeders’ Cup,” Rosenblum said, who turned down a job at an advertising agency in San Francisco to help launch the company. "The social media just went viral, it was such a great experience.”

Growing up in the digital age, McGill and Rosenblum aim to merge technology with an industry that’s steeped in centuries of tradition.

“We always say racing is a few beats behind when it comes to catching onto something new and I think those beats are starting to catch up," McGill said, whose professional relationship with the Breeders’ Cup began with her as an intern a decade ago.

Despite those challenges, the pair says Grand Slam Social's client list and staff are growing. The team can often be found tweeting and posting from just about anywhere in the world where prized thoroughbreds are run.

“The days I get to be on the road and come cover the races live, those are my favorite days of the year,” McGill said, who spent part of Saturday afternoon hosting a Facebook Live from Saratoga’s paddock for one of their newer clients, My Racehorse.

When they're not running their clients' social media pages, they are usually finding new ways to engage fans — especially at Breeders' Cup — qualifying events like Saturday's Whitney Stakes at Saratoga. 

“We had the Peacock Paddock [on Saturday], which is a social media activation where are you can go in to take your photo and tweet with the hashtag,” Rosenblum said.

“What’s a day off?” McGill joked. “I mean, when you are doing social media, you are 24 hours a day connected.”

With a love of social media and horses, that constant hustle is part of what's fueled Grand Slam Social's success.

"I absolutely love it,” Rosenblum said. “It is just like a dream come true.”

"I still pinch myself,” McGill said. “We built something and it's still growing, and it’s something I am incredibly proud of.”
