Chicago – September 12, 2026 -- Protein2o has appointed Mark Rappaport as Chief Executive Officer and Board member, pairing the leadership change with a new growth investment aimed at expanding the clear protein beverage maker's retail footprint and innovation pipeline.
Rappaport joins from Congo Brands, where he served as Global Chief Commercial Officer
Rappaport most recently led the global commercial organization at Congo Brands, overseeing a portfolio that includes Alani Nu. He spent over two decades scaling beverage and consumer brands, including senior leadership roles at Red Bull, where he ran the company's U.S. business and distribution organization during a period of significant growth.
New capital will fund brand building, retail expansion and product innovation
The investment is earmarked for organizational capabilities, retail development and an expanded innovation pipeline intended to extend clear protein into new consumer occasions and formats. Protein2o positions its products as a lighter, non-milky alternative to traditional protein shakes, and currently sells through major U.S. retailers and e-commerce platforms.
Board Chairman cites Rappaport's brand-building track record in leadership pick
Chris Running, Chairman of Protein2o's Board, said Rappaport combines brand-building and operating experience with an understanding of shifting consumer demand, and has a track record of building high-performing teams and delivering results.
Rappaport said clear protein products can be refreshing and flavorful rather than heavy or filling, and that the company aims to accelerate growth with retail partners while sharpening its brand positioning.
