The partners founded the group after a successful period of gambling on horse and greyhound racing. Their change to the stock exchange has proved very successful, with SIG now employing 2,000 workers worldwide. SIG has invested in numerous private companies to varying rates of success, most recently the group invested in TikTok’s parent company ByteDance and the investment has proved the most valuable holding so far.
