Péter Uj is a Hungarian journalist who is the founder of 444.hu, and the co-founder and former editor-in-chief of Index.hu.

Although Uj was a regular contributor to both Nyírő's previous endavour, ABCD,[3] and Internetto,[6] with many of the website's staff already considering him a member, this was never an official relationship.

[8] In 2012, Uj reunited with his former Index colleague, Albert Gazda at Origo.hu to help transform the website.

[9] In March 2013, news reports broke that Uj was working on a new website, reportedly under the name Jeti Válasz (literally: Yeti Answer, a parody of conservative weekly Heti Válasz) or Magyar Jeti.

[10] A month later, Uj launched 444.hu with the intention of competing with Index and Origo.
