Program areas at Mainframe Studios

In January 2023, Mainframe opened its final floor (Floor 2) of renovated studios and increased its total creative workspaces to 181 studios. The studios are occupied with individual artists and arts related nonprofits. Mainframe operated at a 98% occupancy rate with a waitlist of over 100 applicants. Income from affordable rents generated enough revenue to cover operating costs. The 4650 square foot event space provides a place for weddings, conferences, workshops, corporate parties, and fundraisers to occur for a rental fee. The 2nd floor common area became a learning space where professional development sessions are offered weekly to help artists and small businesses thrive. Mainframe serves as a beacon demonstrating that investing in the creative economy works.
Mainframe Studios spends the majority of its marketing budget on programming for monthly First Friday open studio events that attract thousands of visitors. The festive, free events feature a unique theme and create new experiences for new audiences each month. Theses include exhibitions, activities & special guests relating to various art forms such as ceramics, fashion and printing and community issues. First Fridays also feature local musicians and affordable dinner options by resident caterers Tangerine Food Company. Tenant-artists open their studios to connect with new customers and community members that help further their careers. Artist/tenants also developed and led professional development experiences each week to improve business skills and level up their art practice. Artists/tenants helped re-design the website to promote Mainframe, their studios and classes, and public events. Mainframe also self publishes a quarterly studio directory that includes stories about our artists and partners.
