Within four years, he had 1,300 staff and the Ring had sold out in 16,000 stores. He then sold his company to Amazon for an estimated $1.2 to $1.8 billion in February 2018. As a result, he held between 20% to 30% of the corporation, implying that he would get between $180 and $270 million after taxes.
