About Ion

In 1939, The Sears on Main Street was a prototype futuristic showroom, filled with modern marvels. Today, the revived iconic building is a hub of innovation, connection, sustainability, and economic resilience.

It starts at the Ion:
Where ideas go to grow.

Located at 4201 Main St. in the heart of Ion District, the Ion building is the namesake centerpiece of Houston’s innovation corridor, anchoring a district-wide vision to advance and sustain Houston’s economic resilience—and deliver a better quality of life for each other.

Houston’s HQ for Innovation located in Midtown.

The beautifully revived building—once home to the iconic Sears showroom, itself a modern marvel in 1939—is today a sunlit structure of steel and glass designed to bring Houston’s entrepreneurial, corporate, and academic communities into collaborative spaces and programs. A place for turning imagination and ideas into tangible realities.

From Fortune 500s seeking flexible office space to first-time startups looking for the funding to build a prototype, the Ion invites individuals and teams of all kinds to a place where they can break with convention, break into the tech scene, or simply break up their day with a coffee and easy atmosphere. Anyone is welcome at any time.
