Shared workspaces are a growing trend in St. Louis. Two local women hope their space in Clayton meets an untapped need. They’re targeting both start-up and established businesswomen who want a home base with office amenities and camaraderie. Rise Collaborative Workspace has already attracted a number of women from a wide variety of fields. It includes programming such as financial planning, yoga and a book club. Next, the founders hope to expand their impact to young women in high school and college through a mentorship program.
