Dimitar Petrov recommends this agency

What was the objective behind your collaboration?

The KeyDev team created an online platform for our client - one of the leading buisness schools in France - which had to host 1500 students in real time during the COVID crisis, allowing the students to take part in an interactive onboarding experience, split in groups of 4-5 people, which were connected trough voice chat and writen chat. Each group would have to go trough a series of interactive puzzles, which they would have to solve working together - a kind of "digital escape room".

What did you enjoy the most during your collaboration?

The level of profesionalism and good communication with KeyDev was fantastic! They were quick to propose and find solutions and took responsibnility for finding quick, effective and within the allocated budget solutions to each aspect of this very ambitious project.
