Protein2o Names Mark Rappaport Chief Executive Officer and Announces New Growth Investment

New leadership and investment will accelerate growth and fuel an ambitious new innovation and brand roadmap

CHICAGO, Sept. 8, 2026 /PRNewswire/ -- Protein2o, a pioneer in clear protein, today announced the appointment of Mark Rappaport as Chief Executive Officer and a member of its Board of Directors, alongside a new growth investment in the business. Together, the new leadership and investment mark the beginning of an ambitious new chapter for Protein2o, focused on accelerating growth and building a bold innovation and brand roadmap.

Rappaport brings more than two decades of experience building and scaling some of the world's most recognized beverage and consumer brands. Most recently, he served as Global Chief Commercial Officer of Congo Brands, where he helped lead the global commercial organization across a portfolio of fast-growing consumer brands, including Alani Nu. Previously, Rappaport held senior leadership roles at Red Bull, including responsibility for the company's U.S. business and distribution organization during a period of significant growth.

"Clear protein has immense potential," said Rappaport. "Consumers are beginning to realize that getting more protein doesn't have to mean something heavy, milky or filling. It can be refreshing, flavorful and something you genuinely enjoy. Protein2o was early to this opportunity and already makes great-tasting products that consumers love. Now we have the opportunity to build on that foundation—to accelerate growth with our retail partners while creating a more distinctive, surprising and bold brand that consumers actively seek out. I couldn't be more excited about what we can build from here."

Protein2o has built its business around refreshing, great-tasting clear protein products that offer consumers an alternative to traditional protein shakes. The new investment will support the company's next phase of growth, including brand building, retail development, organizational capabilities and an expanded innovation pipeline designed to bring clear protein to more consumers, occasions and formats.

"Mark brings a rare combination of brand building and operating experience, along with an instinctive understanding of where consumers are going next," said Chris Running, Chairman of the Board of Protein2o. "He has a proven track record of building brands, developing high-performing teams and delivering exceptional results. Just as importantly, Mark is known throughout the industry as a leader of great character who builds strong, lasting relationships with customers, partners and people. We believe he is uniquely suited to lead Protein2o through this next chapter and realize the enormous opportunity ahead."

Protein2o products are available through leading retailers and e-commerce platforms across the United States.
