Howard Tullman, former CEO of 1871. Earlier this year, Tullman said he planned to step down as chief of the city’s high-profile tech hub once a successor is found. Tullman’s involvement with 1871 won’t end — he’ll stay on as a board member and a member of the executive committee — but he won’t say what’s next. Tullman hinted that there are “a couple” of new initiatives he plans to roll out next year, but he declined to share any details.
