| Josep Nos | Carlos Nos Terrado |
ASB alumni and entrepreneur brothers Josep (Class of 2014) and Carlos Nos (Class of 2020) have a knack for building products people actually need.
After ASB, Josep studied Business Administration at IQS Barcelona, graduating in 2018, the same year he founded Protella®, a brand of healthy snacks. Carlos went on to study Marketing at ESIC Business & Marketing School, graduating in 2024, and later joined his brother at Protella, where the two are now co-owners. Follow Protella at @protella.
Their latest venture, Gudslip, makes mouth tapes and nasal strips designed to improve breathing for better sleep and athletic performance. With more than 10,000 Gudslip strips already sold in pharmacies across Spain and exports reaching over 19 countries worldwide, the brothers say the project has them more motivated than ever to reach their goal of becoming the world's most recognized sleep brand.
Building a business alongside a sibling gives Josep and Carlos a competitive edge built on trust and understanding, and we can't wait to see what they do next. Follow Gudslip at @gudsliptape.
