Eduard Kučera Net Worth

Eduard Kučera has an estimated net worth of $1.5 billion, according to Forbes Real-Time Billionaires, Eduard Kučera profile (figures as of October 20, 2026). That is up from $1.1 billion in 2021.

Eduard Kučera is a Czech software engineer and entrepreneur best known as cofounder of Avast, the internet security company. He was born on January 11, 1953, and studied physical electronics at the Faculty of Mathematics and Physics of Charles University in Prague.

After university he worked at the Research Institute of Mathematical Machines in Prague, where he helped develop printers and met his future business partner, Pavel Baudiš. Kučera is one of the biggest watch collectors in Czechia and owns a large vintage car collection with his son.

He and his wife, Milada Kučerová, are also known for supporting Czech culture. In 2022 they received a Czech Lion award for their support of the digital restoration of Czech films. In 2010 he and Baudiš founded the Avast Foundation to back charitable projects in the Czech Republic.

How Eduard Kučera made his money

In 1988 Baudiš wrote software to remove the Vienna computer virus, and the two men started a business to sell it, called ALWIL. After the fall of Communism in 1989 the company grew, and Kučera took charge of its operations in 1991. He ran Alwil Software, which became Avast, until 2009 and chaired the company from 2006 to 2014.

In 2002 he steered Avast toward a freemium model, giving antivirus software away to consumers and charging for extra products. That approach drove its global growth. Avast went public in London in 2018 and now protects more than 435 million users. In 2021 it agreed to merge with NortonLifeLock, and Kučera kept a stake in the combined company, now called Gen Digital.

The rise of Avast is one of the best known success stories in Czech technology. A tiny company started in the last years of Communism grew into a global brand used by hundreds of millions of people, and it turned both of its founders into billionaires.
