The Midwest has its own week where the tech industry takes over a whole city. Every spring, downtown St. Louis fills with developers, founders, investors, and students for five days of summits, expos, and pitch competitions. That week is STL TechWeek, and the 2026 edition was its biggest one yet.
St. Louis Tech Week 2026 ran from April 13 to 17, 2026, organized by TechSTL, the St. Louis metro tech council. More than 10,000 attendees joined across 10 innovation tracks, and every event was free. This guide recaps what happened and what to expect when the next edition is announced.
What Is St. Louis Tech Week?
St. Louis Tech Week, often styled STL TechWeek, is a week-long, citywide technology festival organized by TechSTL. The 2026 edition was the fourth annual. Unlike single-venue conferences, it spreads dozens of events across the St. Louis metro area, from the convention center downtown to innovation hubs, universities, and breweries.
The format covers 10 innovation tracks, including AI, cybersecurity, fintech and ecommerce, bio and healthtech, agtech and foodtech, geospatial tech, and defense innovation. Flagship events anchor the week, while community meetups and mixers fill the gaps. For how it compares to other city tech weeks, see our tech conferences in 2026 calendar.
When Was St. Louis Tech Week 2026?
The 2026 edition took place from Monday, April 13 to Friday, April 17, 2026. It was the fourth annual STL TechWeek.
Dates for the 2027 edition have not been announced yet. TechSTL typically confirms the next year’s dates a few months in advance, so check the official TechSTL site toward the end of the year. We will update this guide when 2027 dates go live.
Where Does St. Louis Tech Week Take Place?
The main venue for 2026 was the America’s Center Convention Complex at 701 Convention Plaza in downtown St. Louis. The two-day AI Summit was held at the Dome at America’s Center.
Events spread well beyond the convention center. The 2026 venue list included T-REX, the downtown innovation hub, The Post Building, the St. Charles Convention Center, the Microsoft Innovation Hub, the Danforth Plant Science Center, Webster University, and Schlafly Bottleworks. That mix of corporate, academic, and community venues is part of the week’s character.
What Events Happened During St. Louis Tech Week 2026?
The week packed in a full program across its five days:
- AI Summit (2 days): keynotes, breakout sessions, and a vendor fair at the Dome at America’s Center.
- Tech Expo (full day): the week’s main exhibition floor.
- DevLAB: a developers conference for working engineers.
- CyberCon: the cybersecurity track’s dedicated event, which hit its 120-person capacity.
- GeoNEXT: the geospatial technology event, capped at 300 attendees.
- Gateway to Innovation: a long-running St. Louis tech conference folded into the week.
- Midwest E-Commerce Summit and Digital Transformation Summit: industry-focused tracks.
- Breakthrough Health Innovation Symposium: the bio and healthtech track.
- Immersiv: media and design programming.
- StartupSTL $10K University Pitch Competition: the flagship startup pitch event at T-REX. If you follow startup demo days, this is the Midwest edition to watch.
Community events rounded out the week: the Black Tech STL Mixer and Digital Marketplace (600 attendees), the Women Tech Leaders Mixer (200 attendees), and Tech on Tap STL (250 attendees). Several events hit capacity, so 2027 attendees should register the moment tickets open.
How Much Did St. Louis Tech Week 2026 Tickets Cost?
Nothing. Every event during STL TechWeek 2026 was free. The official Eventbrite collection page advertised “free events all over the region,” and TechSTL’s executive director confirmed that even the two-day AI Summit carried no ticket price.
Free does not mean unlimited. Capacity-limited events like CyberCon, the Women Tech Leaders Mixer, and GeoNEXT filled up, so registering early was the only way in. Expect the same dynamic for 2027: free, but first come, first served.
Who Should Attend St. Louis Tech Week?
Developers and Engineers
DevLAB, the AI Summit breakouts, and CyberCon give working technologists a full week of technical content without the travel budget a coastal conference demands.
Founders and Startups
The StartupSTL pitch competition, the Tech Expo floor, and the investor presence across the week make it a genuine fundraising and partnership venue. T-REX, the downtown innovation hub, anchors much of the startup programming.
Students and Career Switchers
With free tickets across the board, the week is one of the most accessible on-ramps into tech in the Midwest. Mixers like Black Tech STL and the Women Tech Leaders Mixer are built for networking and hiring conversations.
