How Parallel Helped Bring ProSo Protein Soda to Walmart Marketplace
The Parallel Collective partnered with ProSo Protein Soda to support its Walmart Marketplace onboarding, bringing three flavors to Walmart.com
October 13, 2026 - ProSo Protein Soda has officially launched on Walmart.com.
Retro Root Beer, Cheeky Cherry Vanilla, and Sunny Meyer Lemon are now set up and ready to sell through Walmart Marketplace, and The Parallel Collective is proud to have played a part in getting them there.
Meet ProSo
Founded by Sam Kramer, a Registered Dietitian, and Dalton Anderson, ProSo is bringing something different to the beverage aisle.
Each can contains 10g of whey protein isolate, zero sugar, and just 45 calories. Light, crisp, and never chalky, ProSo combines the familiar experience of drinking soda with the added benefit of protein.
Built for more than the traditional fitness consumer, ProSo is designed for everyday shoppers looking for a better-for-you alternative to conventional soft drinks.
A New Opportunity on Walmart.com
The modern soda category continues to evolve as consumers look for beverages that offer more than traditional soft drinks.
For emerging brands like ProSo, Walmart Marketplace presents an opportunity to reach shoppers nationwide and establish a presence within one of the country's largest retail ecosystems.
But bringing a product to a major retail platform requires more than a great product. Brands need to understand retailer expectations, navigate onboarding requirements, and ensure their products are ready for the digital shelf.
That's where Parallel came in.
How Parallel Supported ProSo's Marketplace Launch
Making the connection. Parallel helped introduce ProSo to the appropriate Walmart contacts during the retailer's Modern Soda review, opening the door for conversations that ultimately led to the Marketplace opportunity.
Providing strategic guidance. Throughout the process, Parallel worked alongside ProSo's team to help navigate retailer expectations, position the brand, and identify the steps needed to move forward.
Facilitating Marketplace onboarding. Parallel helped coordinate communication and onboarding efforts between ProSo and Walmart, supporting the process of getting all three flavors approved, set up, and ready to sell on Walmart.com.
The result is a new national online sales channel for ProSo and an important milestone in the brand's continued growth.
What's Next
For ProSo, launching on Walmart Marketplace represents an opportunity to introduce its products to a much broader audience and continue building momentum in the growing modern soda category.
For Parallel, it's another example of how we work alongside brands to navigate retail opportunities, strengthen their digital presence, and prepare products for success across major retail platforms.
We're proud to have partnered with Sam, Dalton, and the ProSo team on this milestone and look forward to seeing what's ahead.
