About The Founder

Hi, I’m Macy Overcash — Owner, Founder, and CEO of Mills & Co. Social Media Marketing, LLC and Mills Digital Media Boutique.

Since launching Mills & Co. in 2019, I’ve partnered with businesses of every size — from local boutiques and Realtors to national franchises — to transform their digital presence and drive measurable growth. My mission has always been clear: to help brands not just “post,” but to thrive through smart, strategic, and creative social media marketing.

Over the years, I’ve built a proven track record of success:

Andy’s Frozen Custard – I’ve grown the Carolinas’ market Instagram accounts from the ground up, with one video alone reaching 7 million views and boosting followers by 7,000 in just a few weeks. Multiple TikToks have gone viral, crossing millions of views and significantly increasing in-store engagement.
Boutiques & Small Businesses – From fashion retailers to event planners, I’ve crafted social strategies that consistently drive new customers, grow communities, and spark conversations that convert.
Authors & Influencers – With creative campaign launches, I’ve helped authors break into new audiences and establish brand recognition in competitive spaces like the Bookstagram community.

What makes Mills & Co. different is my approach — a blend of storytelling, data-driven insight, and bold creativity. I believe every business has a story worth sharing, and my job is to make sure it reaches the right audience, at the right time, in the right way.

Whether it’s managing full-scale social campaigns, designing trendsetting content, or consulting on high-impact ad strategies, I bring fresh ideas backed by results.

If you’re ready to elevate your brand, go viral, and build a community that loves your business as much as you do — I’m here to help you make it happen.
