Born in Bihać to a Yugoslav People's Army (JNA) officer father, Radulović graduated from the University of Sarajevo's Faculty of Electrical Engineering, specialising in automation and electronics.
[2] In the 1980s, Radulović was part of the New Primitivism cultural movement created in Sarajevo, together with Emir Kusturica and members of the rock band Zabranjeno Pušenje.
His close associate Dušan Pavlović also comes from 1980s Yugoslav pop culture, as a former member of the Belgrade-based band Vampiri.
[5] The following year, he began working at Siemens AG on system monitoring for nuclear plants located in Germany, United States, and Russia.
Radulović came back to Serbia from the United States in 2005, and became a pioneer blogger, writing on economics, business and tax reforms.
Radulović worked as Advisor to the Council of Europe, OSCE, US Embassy, GIZ, NALED, and the Association of Small and Medium Enterprises.
During his brief tenure, he attempted to pass a new labour law package, which was initially supported by the government.
[9] He came to the fore for a text in the magazine Nedeljnik in which he fiercely criticised their former economic policy in Serbia, including the privatisation process and the associated corruption.
[11] On 2 February 2014, Radulović announced that he would participate in the parliamentary elections on 16 March 2014 with his own list.
[3] At the 2016 Serbian parliamentary election, his movement Dosta je bilo tripled its support and with 6.02% of votes it obtained 16 seats.
[14] Radulović initially did not prioritise running for president, as he first proposed that Saša Janković and Vuk Jeremić come to an agreement on a "united candidate" against Aleksandar Vučić.
"[16] Večernje Novosti reported that Janković rejected the offer, while Jeremić's campaign allegedly did not respond.
[17] A week before the election, Nedeljnik published an essay written by Radulović, titled "When I become president", in an appeal to the voters.
[18] In the essay, he argued against party employment and outlines some of his ideas on welfare and taxes: "When we stop the robbery through party employment and subsidies, when we consider the parasitical system which destroys us, we will be able to bring back the taken pensions, raise payments for education workers, for the army, police, and public sector, reduce taxes by a third for the economy to breathe, we will be able to instate a universal social protection and guaranteed basic pensions for all citizens in Serbia who turn 65 years old.
[19] Vladimir Vuletić, a sociology professor at the University of Belgrade, commented that "after last year's parliamentary election, it seemed that [Radulović] represented some kind of future of the opposition.
He is strongly opposed to Middle Eastern immigrants being granted asylum in Serbia,[22] commonly expresses heavy criticism of the Serbian mainstream media, calling them "propaganda channels" and "the enemy of the Serbian people, the state and democracy",[23] and often accuses political opponents of treason and collaboration with "occupiers and colonizers".
[30] He has also made claims that COVID-19 vaccination is the cause of the late 2020 and early 2021 global wave of infections, challenged beliefs that mass immunisation is the only way to end the pandemic and questioned the origins of the virus, leading critics to label him an anti-vaxxer and conspiracy theorist.
