A range of sports technology startups showcased their products at the San Francisco 49ers and SportTechie Horizon Summit. Attendees had the chance to discuss the handling of consumer and athlete data to improve fan engagement and sports performance, or to learn more about how sports betting is changing the way we interact with our favorite teams and leagues. And then they could put down their notebooks and business cards and get even more interactive with augmented reality apps, experimental AR and virtual reality experiences, or try their hand at throwing or hitting balls against a giant video game screen.
