Ready to make an impact? Let’s build something incredible together.SOUSWe launched SOUS two years ago as a pure marketplace to help restaurants and chefs create new revenue streams. In just two years, we enabled our initial clients to generate over €10M in additional revenue, focusing on a single category—chef meal kits.Along the way, we built tech & systems to address our clients' operational challenges, including tools for managing online listings, tracking orders and logistics, and optimizing marketing. This backend solution quickly evolved into our core product and expanded our reach to the broader €100B+ food and beverage market across the EU—including restaurants, online chefs, catering companies, and specialty CPG brands.Today, we’re building on this foundation with a vertical SaaS product designed to simplify online commerce for independent F&B brands across Europe. We’ve already earned the trust of some of the Netherlands' best restaurants, and we’re excited to keep growing!
