The Anticorruption Hackathon Známkamaráda challenged the corrupted system and the politicians who got used to that they can get away with almost everything. They got used to that people are still scared after the 45 years of communism to speak up and get involved. Almost 194 IT specialists grouped together and by the hackathon took an action on the government against the overpriced IT contract. They took all media and public opinion on its side and politicians must react and finally open a dialog. Something, that never happened before. Hackathon Známkamaráda showed ordinary people that their voice matter and they can challenge the system any time its not working for public well being.

Our target was the Czech national character that shaped 45 years of communism. Politicians in the Czech Republic got used to think that they can get away with almost everything. The last drop on the list of corruption scandals was an overpriced e-shop for a highway vignettes. The contract for Asseco group to build an e-commerce platform (for selling highway vignettes) was worth 16 000 000 EUR without an open bid. This extremely overpriced contract got attention of the anticorruption group called Znamkamarada who made an open call and organized the anticorruption hackathon. They invited programmers from whole country to build the e-commerce platform in 48h and for free, in order to show how ridiculous the overpriced contract is.

The creative idea was to fight the corrupted system very straightforward and very public and visible way. We could not stand up to the government as individuals, but as a legitimate representatives of public. We organized Anticorruption Hackathon and made an open call to IT specialists from whole country. They could join and create the platform for free during 48 hours. 194 coders came to make this happen. Whole country was watching and government had to react.

Tomas Vondracek (representing Znamkamarada group) made a call to action via LinkedIn post as a reaction to overpriced contract. He made an open call for volunteers from IT and announced to build together a solution to show that 16 000 000 EUR is ridiculously overpriced.

His post got attention to thousands of relevant people from the field, and moreover attracted the media and attention of Prime Minister within couple of hours. Prime Minister after that called for a meeting. Politicians in the Czech Republic never talked to ordinary people before, talking into consideration their opinions.

The anticorruption hackathon Znamkamarada challenged the suspicious and overpriced contract for 16 000 000 EUR to build an e-commerce platform (for selling highway vignettes). To prove their point, they made an open call for IT volunteers to build the system by themselves in 48 hours and for free.
