Fit Reisen Group is a global leader in health and wellness travel. The company has been operational since 1975 and since then has grown to cover seven brands — Fit Reisen, SpaDreams, Yoga Escapes, Aytour, Kurz-mal-weg.de, Tripz, and Lotus Travel — and four locations in Germany. Fit Reisen Group offers travel products with a strong focus on health — Ayurveda, spa, yoga, detox, beauty, and anti-stress packages — as well as travel vouchers, short trips, city tours, or sports trips for individual travelers (FITs), couples, and families with children.
Initially, the client operated a primary website with very limited functionality, built using an outdated .NET tech stack. The major sales channel was phone calls, while the share of online sales was very low, with no automation in place. It led to slow response times, fragmented booking processes, and certain technological constraints for the company’s scalability.
For instance, when a customer wanted to buy a package tour, most arrangements were made via phone communication between a sales manager and a hotel/the customer. In addition, the entire multilingual content was added/updated by content managers, with no automation to speed up the process as well.
The client wanted to get a new ERP system by upgrading their main website (fitreisen.de) to drive website conversions and online sales and get a fully functional online sales channel. Apart from that, Fit Reisen requested support and development of new features and applications, including a CMS portal. As development progressed, our team was also assigned to additional projects of the same client (tripz.de and lotus-travel.com).
Our team had to develop the entire functionality for the client from the ground up. The solution had to be tailored to fit the client’s specific requirements and accommodate their rich travel product portfolio.
The project started back in 2016 with the redevelopment of the main website and covered almost a decade of fruitful collaboration. Over time, we extended the functionality of the main project (fitreisen.de), developed a content management portal from scratch, and took care of additional projects (tripz.de, lotus-travel.com).
On top of that, we handled the client’s requests for the introduction of automation into their processes and delivered the following features:
To implement the content automation module, we integrated OpenAI’s ChatGPT to enable translation into multiple languages. The solution posed no technical challenges and was implemented hassle-free, yet the results exceeded our development efforts and led to a significant decrease of time and efforts for content management and updates.
Communication Tools — Slack, Teams
Our cooperation brought to life three fully-operational and marketing websites — fitreisen.de, tripz.de, and lotus-travel.com.

The project is still in active development, as our team is working on further upgrades to the functionality, ongoing support, and the integration of OpenGDS.
