A Pretzel Brand’s Next Chapter Takes Shape with Main Post Backing

Main Post Partners has made an investment in Stellar Snacks, a maker of better-for-you snacks, in partnership with founders Elisabeth Galvin and Gina Galvin.

Stellar Snacks’ products include seasoned pretzel twists, filled pretzel bites, and other limited-edition flavored snacks that are sold through national grocery, mass, club, and natural retail channels, including Costco, Target, Sprouts, Kroger, Albertsons, and Safeway, as well as through airline partnerships with Southwest and Alaska Airlines.Carson City, Nevada-headquartered Stellar Snacks was founded in 2018 by mother-daughter entrepreneurs Chief Executive Officer Elisabeth Galvin and Chief Creative Officer Gina Galvin.

Main Post’s investment follows a period of national expansion for Stellar Snacks, including increased shelf placement across major retailers and capacity additions at its Kentucky operating facility.

“Stellar has built an exceptional brand rooted in product quality, authenticity, and strong consumer loyalty,” said Jeff Mills, a managing partner at Main Post Partners. “We’re impressed by the team’s vision and execution to date and are excited to partner with them to unlock the brand’s next phase of growth.”

“We’re thrilled to embark on this next chapter for the Stellar Snacks family,” said Elisabeth Galvin. “Main Post brings deep experience partnering with founder-led CPG brands, and this partnership means the world to us. The investment will allow us to scale with purpose while staying true to the values that have defined Stellar from the very beginning: quality, creativity, and greatness.”

“Stellar has always been about more than pretzels — it’s about building a brand people feel connected to,” said Gina Galvin. “This partnership feels deeply aligned with our vision, and we’re energized by the opportunity to grow the brand while continuing to build something meaningful for our team, our customers, and our community.”
