Unifying GPO Group under the TYLin name will deliver more effective access to global resources and enhanced collaboration to support clients in the mobility market.

The GPO Group and Sam Schwartz, one of its operating companies, as part of a global effort to enhance connections and collaboration among companies in the Dar Group’s Global Infrastructure (GI) Pillar, are formally aligning with TYLin, the leading brand in the GI Pillar.

The GPO Group and Sam Schwartz have added a TYLin “unifier” line to their names. Effective immediately, GPO will be known as GPO, A TYLin Company. Similarly, Sam Schwartz will be known as Sam Schwartz, A TYLin Company.


The addition of the unifier line is part of a global strategic initiative to unify the companies in the Dar Group GI Pillar under the TYLin brand to provide more efficient access to its vast global resources and promote better collaboration among its staff. Aligning the two companies with TYLin — particularly in the rail and transit segments — means that GPO and Sam Schwartz, transportation and mobility leaders in Europe and the Americas, respectively, will expand their ability to deliver innovative thinking and practical implementation across all aspects of physical and digital mobility networks.

“By strategically aligning TYLin, GPO and Sam Schwartz we will strengthen our ability to provide innovative solutions based on real-world insights from around the globe,” said Matthew Cummings, President, and Chief Executive Officer, TYLin. “This alignment will ultimately help us achieve our shared goal of developing smarter cities and connecting communities.”

“Aligning with the TYLin brand complements and expands our presence and technical expertise in Europe and in the Americas and will allow us to connect our people, places and ideas more efficiently to meet our clients’ evolving needs around the world,” said Xavier Montobbio, President, and Chief Executive Officer of the GPO Group. “This effort to enhance collaboration and connections is embodied in the addition of the ‘unifier’ line to the GPO and Sam Schwartz company names.”

Earlier this year, TYLin launched a brand strategy to unify its global operations. The unified brand connects clients more effectively with TYLin’s multi-discipline global engineering resources to solve infrastructure challenges with innovative solutions at the regional and local levels in the Aviation; Bridge; Buildings; Ports + Marine; Rail + Transit; Roads + Highways; and Water sectors.
