Chris Kelly, who also serves as vice chairman, will resign from the flexible office provider by the end of the year, according to Commercial Observer.
Convene has raised $260 million since its founding in 2009.
Kelly announced the decision Friday at a company meeting.
The departure leaves open the role of vice chairman and president, a position Kelly vacated in February.
Convene doesn’t plan to find a new vice chairman and has put aside hiring a new president, Kelly said.
Kelly, who co-founded New York-based Convene with CEO Ryan Simonetti, said he plans to take some time off before his next full-time role.
At the under-construction tower, Convene will offer 50,000 square feet for meetings and conferences and an additional 50,000 square feet for flexible office space.
