Demand has been high for off-the-wall virtual parties, said Jonathan Como, founder of Offsyte, a marketplace for corporate team events, which has organized online holiday events for companies including health insurance giant Blue Shield, the ride-hailing company Lyft, and the dating app Tinder. Most popular are celebrations that involve sending food and drink to employees for online cocktail or chocolate-making classes, Como said. Also big are virtual escape rooms where employees can play games. That's the route marketing firm Rank Fuse is taking, bringing its employees together for a virtual murder mystery through Red Herring Games, said Chelsea Roller, culture manager at the Overland Park, Kansas, firm, which normally organizes a holiday dinner or bowling party.
