What our clients say about us

review

Sealed Code has provided solutions for handling participant registration for Viessmann Academy stationary trainings. Additionally, Viessmann has invested greatly in development of e-learning platforms that allow users to obtain specialist qualifications without the need to participate in a stationary training. Viessmann Academy has nothing but good experience in cooperating with Sealed Code in that department. We also appreciate the remarkable flexibility of the developers and the impressive pace of fixing any issues or implementing new functionalities.

review

We have started working together way back in 2008 by creating a system used by 24/7 Service Hotline that coordinates the work of a service partner network responsible for startups and maintenance of Viessmann manufactured devices. Currently, Sealed Code is responsible with providing undisrupted functioning of an ecosystem consisting of multiple systems used by thousands of users every day. Starting with Viessmann employees, through Service Partners network up to Viessmann devices users. Solutions deployed by Sealed Code are constantly evolving and they span a growing number of Viessmann's Poland operations.
