T eddy Sagi is an Israeli billionaire entrepreneur who has built a vast fortune in the online gambling software and technology industries. His career-defining success was the founding of Playtech in 1999. He founded the company in Estonia and built it into one of the world's largest and most successful suppliers of software and services for the online gambling industry. Playtech provides the underlying technology platform for a huge number of online casinos, poker rooms, and sports betting sites around the world. He took the company public on the London Stock Exchange and has since sold his entire stake in a series of deals that netted him billions.

After his success with Playtech, Sagi has become a prolific investor in technology and real estate. He is the founder of the e-commerce marketing platform Kape Technologies and the online payments company SafeCharge, which he also took public and later sold. He has also built a massive real estate empire, particularly in London, where he is a major owner of iconic market properties, including Camden Market and Stables Market, which he is redeveloping into a modern retail and co-working hub.
