Zone7 announced last month it had raised $2.5 million in seed funding from a Resolute Ventures-led group, which also included Amicus Capital Partners, PLG Ventures, UpWest Labs, Dave Pell, PLG Ventures and UpWest, as well as former and current athletes, including the National Basketball Association's Kristaps Porzingis. Zone7, a 10-person startup, said Major League Baseball, professional soccer teams and several college programs are using its system, although the company declined to name the teams. However, the Maccabi Tel Aviv Football Club, an Israeli pro team, has tested the technology, according to Jordi Cruyff, who was the team's sports director from 2012 to 2017. Mr. Cruyff is also a former player and one-time member of some of the biggest teams in the sport, including FC Barcelona and Manchester United Football Club. With Maccabi, Mr. Cruyff said he would receive daily alerts from Zone7 that certain players were at high risk.
