Cerealto (formerly Grupo Siro) is Europe's largest third-party manufacturer of cereal-based foods — biscuits, breakfast cereals, cereal bars, snacks and pasta — supplying private-label products to retailers and food brands across Europe, the UK, US and Mexico. It is a mature, established industrial group (~3,600 employees, 12 plants, ~€574M revenue in 2025), not a VC-backed startup; it was recapitalized by private-equity/special-situations investors after 2022 financial distress, and recently secured a €110M syndicated loan (2026).
