Whammychat: short-lived, playful chat-rooms.


each chat-room created lasts for a maximum of 20 minutes.


a big component of gaming is integrated. Users can battle each other mid-chat to prove a certain point by using skills, which enable them to damage, heal and decorate other messages.


A discussion on a particular topic can be started with friends and/or strangers.

Story behind the concept:

Kavi went to watch Batman vs. Superman as he arrived in Germany for his studies mid-2016. The movie was well.. not that great, but there was an epic ending-scene where Superman and Doomsday start fighting. Superman starts blowing his lazer eyes at Doomsday in an attempt to blow him into smithereens. At this point, Kavi got a message on a popular instant-messaging app that rattled his nerves. He did not know how to express his anger via messaging and at this point of time he saw Superman shooting his lazer beams. That is when it clicked to him about the possibility of summoning Superman in his conversation to blow his friend’s message into bits and pieces to express himself. This would show his friend that he was frustrated with the message and also would be fun to use. The idea was born out of the boredom of current chat-platforms and the frustration of not being able to express oneself.

The founding:

After the idea was born, Kavi started a team with Federico to make the prototype. After a long journey to finish building the protoype, it was able to convince our designer, Andrej, and front-end developer, Philipp, to join the team.
