History
Portfolio Stock Exchange was established as a multilateral trading facility (MTF) under European Union regulations, authorised by the Spanish National Stock Markets Authority (CNMV). It was created to address what its founders describe as a broken business model of traditional stock exchanges, aiming to provide a more accessible, cost-effective, and integrated platform for both issuers and investors. The exchange's core innovation is the combination of primary and secondary markets on a single platform, integrating custody and post-trade processes. This design is intended to reduce costs by as much as 90% compared to traditional exchanges. Portfolio targets a wide range of issuers, from real estate and mid-cap companies to tech startups, family businesses, and alternative investment funds. The leadership team includes co-founder and CEO Santiago Navarro de Andrés, a former banking and finance lawyer at Ashurst LLP, and co-founder Mariano Torrecilla Lahuerta, a serial tech entrepreneur. The chairman is Rafael de Cascante, former board member and head of legal at Santander Bank Capital Markets. Other key executives bring experience from Santander, JPMorgan Chase, Abengoa, BNP Paribas, and other financial institutions. As of its public launch, Portfolio Stock Exchange operates as a private company based in Spain, serving the European market. It continues to develop its platform and expand its offering to various asset classes and issuer types.
