Playtech co-founder Teddy Sagi has sold 4.1 percent of his stake in the world’s largest gambling software company.

The Financial Times reported that Sagi unloaded 13 million shares worth £113 million (US$139 million) as he ventures into the British property sector.

Sagi said that he sold his shares to French firm Boussard & Gavaudan Investment Management at 872.5p, as he wanted “to further develop my London property portfolio and be at the vanguard of the co-working revolution.”

As part of a “lock-up” agreement that will expire on May 29, the Playtech co-founder and Boussard have agreed not to sell any shares in gaming tech firm.
