100state, a Madison co-working community that says it is the largest in Wisconsin, is changing leaders.

Gregory St. Fort, who has been executive director since September 2015, is stepping down and Claudia Seidenberg will take the helm, starting Monday.

Seidenberg, who graduated from UW-Madison in May, has been in charge of operations at 100state for three years, and said she is “excited and honored” to take on her new role.

St. Fort said he plans to travel, and will work on a business he started several years ago, Let’s Keep Building.

Aimed at helping entrepreneurs, Let’s Keep Building’s mission is “to build spaces and products that connect, support and inspire entrepreneurs from all communities,” its website says.

St. Fort said he plans to start a new company this fall that will have some relation to Let’s Keep Building, but he is keeping details under wraps, for now.

“I expect to come back to Madison at some point,” he said, mentioning many friends and mentors here.

100state, which started at 100 State St. in June 2013, operates in the 316 W. Washington Ave. tech hub. The nonprofit organization has more than 300 members, St. Fort said.
