INESC institutes welcome the European Commission’s initiative to create an optional EU-wide corporate legal framework, the “28th Regime”, to help innovative companies set up, scale and operate across the Single Market. For INESC’s spin-offs and industry collaborations, a predictable, digital-by-default company form that investors trust could cut transaction costs, speed up cross-border growth and unlock private capital. INESC stresses that the regime must be optional and modular, compatible with national systems, linked to the European Innovation Act, and suited to SMEs, without weakening Member State standards on labour, taxation or the environment, or adding new bureaucracy.
