Opus Interactive, a data center company, is revitalizing two floors in a downtown Portland building originally designed for data hosting but left vacant after the dot-com bubble. The center will feature 40,000 square feet of space and is expected to support the growing demand for data services from tech companies, as major firms in California plan expansions in Oregon. As the economy improves, Opus aims to attract clients by offering cost-effective IT solutions compared to in-house departments.
