Who we are

Comerciando Global is a consulting firm located in Madrid, specialized in providing consultancy services in various business management areas, with expertise in international strategic planning.

Comerciando Global, founded in  2001 with the development of the concept and business strategy of the “Xportplus” project, an innovative B2B platform developed under the V R + D + i FRAMEWORK PROGRAMME of the European Union by a consortium of 13 private and institutional partners from 8 different European countries. The project obtained 1.7 million € EU funding. All intellectual property and exploitation rights of the platform belong to Comerciando Global.

The platform (prototype level) has content in 7 languages. It provides SMEs with tools, which are often only available to multinationals, to compete internationally by performing a variety of foreign trade operations. This includes document management and the design of e­-government proposals for several administrations.

The project received several awards in Spain, such as, the best entrepreneurial project of the year from the Foundation RTVE / INEM and INCYDE. We were also a finalist and winner of the NETI and CREARA awards from IE and lESE, respectively, for the best business plan. In addition, a finalist position for the Academic Entrepreneurs award from the Everis Foundation.

For several years Comerciando Global oversaw the international strategy of the Quality Pascual Group. We designed a winning strategy to modify the European legislation of fermented milks, dismantling technical barriers to enable trade at the global level. Skillful negotiations at various levels with consumer associations, Ministries of different Member States, governmental entities, such as, the American Food & Drug Administration (FDA), the Codex Alimentarius or the European Commission, as well as, with the main European dairy and food producers, enabled the success.
