Interes

Based in Darmstadt, Germany, Interes GmbH has established itself as a durable player in the travel technology sector since its founding in 1997 by Volker Herrmann. The firm specializes in developing software for the travel industry, with a particular focus on complex flight distribution solutions. Its clientele includes a range of international businesses such as tour operators, travel agency chains, global distribution systems, and airlines.

The company’s core offering is the Mercado Suite, a product family designed to streamline air travel procurement and sales. This suite includes the Mercado Server, which acts as a content aggregator, enabling clients to source airfares from multiple channels like GDS, NDC APIs, and direct connects with a single query. Another component, the Mercado Agent, provides a unified graphical interface for travel agents to search and book flights from these varied sources. To manage profitability, the suite features the Mercado Mark-up & Rules Engine for optimizing margins. For airlines, Interes provides the Airline Retail Engine, an offer and order management system developed to leverage IATA's NDC and ONE Order standards for modern retailing.

The business operates by providing these sophisticated software solutions to both corporate and leisure travel segments, primarily in Europe. Interes was an owner-managed family business for much of its history, with Volker Herrmann serving as CEO. On January 14, 2025, the company was acquired by the Juniper Group in a transaction facilitated by the institutional investor ennea capital partners. This acquisition marks a significant milestone in the company's more than two-decade history, positioning it as an operating subsidiary within a larger group.
