The former St. Louis Post-Dispatch complex on North Tucker is no longer churning out newspapers but it is busy again. The hulking landmark has been remade into a downtown tech campus, drawing fintech and geospatial companies along with a nonprofit training pipeline for cybersecurity workers. Where presses once roared, there are now offices, labs and a sizable event hall meant to bring employers and students into the same orbit.
A New Chapter for the Building
The eight-story structure holds roughly 160,000 square feet of rentable space and an event hall that can fit about 800 people. "We want to be a conduit for people and information, just like the newspaper was," Claire Anderson said, as reported by KMOV.
From Newsroom to Startup Campus
Design firm Trivers reports the building has been rebranded as 900 N. Tucker and that the overhaul keeps much of the paper’s historic character intact while adding flexible floorplates for offices and labs, according to Trivers. The updated layout combines traditional office suites with public-facing event and training areas, a mix intended to serve both corporate tenants and community programs in the same address.
Scale AI and a Defense-Tech Cluster
San Francisco-based Scale AI opened a St. Louis lab in the building last fall, keeping more than 250 local employees downtown and helping to anchor a growing geospatial and defense-tech cluster, according to the St. Louis Post-Dispatch. Company leaders told the paper they expect being near other firms and the nearby NGA campus to speed up collaboration and hiring.
Cybersecurity Training and Workforce Development
Among the newer tenants is Cyber-Up, a St. Louis nonprofit that moved into the building to run bootcamps and certificate programs geared toward nontraditional students. Tony Bryan of Cyber-Up told KMOV that the group’s mission is to "ignite curiosity" and connect people to tech career pathways, and recent graduate Cassandra Britt said her cybersecurity credential could open the door to a promotion or a new job.
What It Means for Downtown
Developers and civic leaders say the blend of startups, corporate offices and training programs could help steady downtown’s recovery even while the wider office market is still on shaky ground. Cushman & Wakefield’s MarketBeat cites roughly an 18.5 percent vacancy rate for the St. Louis office market, highlighting how hard it is to fill conventional towers even as niche hubs emerge, per Cushman & Wakefield.
For now, the old Post building functions as an adaptive reuse experiment, preserving a civic landmark while turning its rooms into places to teach, hire and collaborate. Owners and local organizers say the real proof will be whether the block can sustain long-term hiring and steady weekday foot traffic downtown.
