Dallas-based Smoothie King has received a strategic, minority growth investment from Main Post Partners, a San Francisco-based consumer-focused private equity firm specializing in founder-run, high-growth challenger brands.

Smoothie King said the partnership marks “a powerful new chapter” for the brand, positioning it for accelerated growth, innovation, and market leadership.

The amount of the investment was not disclosed.

“At Smoothie King, our vision is to make the world a better place by nourishing healthy habits, and that starts with having partners who share our vision and embrace our values,” Wan Kim, CEO and majority shareholder of Smoothie King, said in a statement. “We’ve been extremely impressed by Main Post’s track record of growing franchise brands the right way—by building a strong culture, focusing on the guest, and always thinking long term.”

Main Post has also invested in Jimmy John’s, Flynn Group

With decades of experience partnering with high-growth franchisor concepts such as Jimmy John’s and leading franchisee businesses such as Flynn Group, Main Post Partners brings deep operational expertise, expansive industry relationships, and a proven ability to transform brands into category leaders, Smoothie King said.

“This investment is more than capital—it’s a powerful alignment of vision and capability,” Main Post Managing Partner Jeff Mills said in a statement. “We’re very impressed by the strength of the Smoothie King brand and reputation, the quality and innovation of the product offerings and its commitment to the guest experience.”

Mills expressed enthusiasm about the partnership and the company’s future.

“We’re excited to partner with Smoothie King’s strong leadership team and franchisees to support the company in capitalizing on its Clean Blends menu, impressive customer service ranking, 1,200-plus-unit restaurant base and category leadership,” he said. “Smoothie King is well positioned to enter its next phase of growth and fulfill its bold and inspiring vision to become one of America’s favorite brands.”

San Francisco-based North Point acted as the exclusive financial advisor to Smoothie King.

Founded in 1973, Smoothie King, the original U.S. smoothie franchise, has more than 1,200 stores nationwide. The company is headquartered in the Cypress Waters development just southeast of Coppell.

Smoothie King expands its ‘Power Eats Menu’

News of the investment comes as Smoothie King is taking “a major step forward” with the expansion of its Power Eats Menu. Now rolling out to over 100 locations across Dallas-Fort Worth following a successful pilot earlier this year, the expanded menu features “protein-packed, flavorful meals” designed to complement Smoothie King’s iconic smoothies and “fuel healthy, on-the-go lifestyles,” the company said.
