Andy Byron has stepped down as CEO of AI company Astronomer, days after a video of him and Chief People Officer Kristin Cabot appearing on a 'kiss cam' at a Coldplay concert near Boston went viral. The footage, captured at Gillette Stadium in Foxborough, Massachusetts, showed the two embracing before awkwardly slipping out of frame. Coldplay frontman Chris Martin, reacting in real time, joked: "Either they're having an affair or they're just very shy." The moment quickly caught fire online, fuelling speculation - including rumours of an extramarital affair.
