Founded by local entrepreneur Randy Schilling, OPO Startups joined the co-working scene in May 2015, turning the old St. Charles Post Office (Old Post Office, or OPO) into a beautiful, bright space for digital businesses looking to grow.

Now housing lingerie designer Liviara; Chow Checker, designers of an app that increases awareness of allergens in foods; BoardPaq, a company designing a cloud service and apps to help boards of directors go paperless; several independent contractors and more, OPO has earned a solid foothold in the startup community.
