Founding Team

Hyer® Aviation was founded by Max van Doorne and Helder Reis, themselves aircraft pilots with decades of experience in the aviation industry. They recognized that the private charter market is still too complex. Some services, which are usually taken for granted in this sector, are not delivered at the same level as they should be. They built Hyer® to tackle this problem.

Our timeline

  1. The company expanded its services to Germany, Austria and Switzerland. Clients outside the initial closed group were welcomed to book with ENVOY. The company introduced the innovative Smart Quotes, simplifying the process of choosing an aircraft. Shortly after, the client base expanded to the United Kingdom and Spain.

  2. First-of-its-kind Shared Flights were introduced. Repatriation flights were organised in Asia, Africa and Europe with both small and large aircraft. Special solutions for groups and a carbon offset program for private aviation in Benelux were launched. 

  3. ENVOY rebranded to Hyer® Aviation. A new brand, website and a tech-driven strategy were launched, followed by a bold service portfolio. An innovative proprietary platform and an ambitious membership program were released to support better the rapid demand for Hyer® services and exclusive flights.

  4. Hyer developed a client portfolio and launched an exclusive mobile application for its loyal clients. A significant increase in demand, primarily during summer, has led to additional sales teams and flight support.  

We believe that in a world that turns you into a number, we are able to use technology to deliver to you an unparalleled personalised service.
