Top 20 Tech Companies in Houston (2026): IT, Software and Space Tech

Top 20 tech companies in Houston, with a skyline and labels for enterprise IT, energy tech and space

Key Takeaways

1 min summary
  • Job seekers can find tech roles all over Houston, along with the fact that HPE, BMC and KBR run their headquarters right here, giving you more doors to knock on.
  • We also noted that the list lives up to its title, the companies generally are based right here.
  • On the downside, we noted that pure software firms are a little scarce, and the scene can feel spread out at times, with an extra drive between clusters.
  • We loved the wide mix of options offered by Houston's space companies, and the roles at Intuitive Machines and Axiom Space look bolder than most tech jobs.
  • Of course, if you need an app built instead of a job, you'll want a Houston development team like Octal Digital rather than a big product company.
Summarize with AIGet the key points of this post

If your picture of Texas tech is all Austin, you might want to look at a slightly more down-to-earth tech scene: Houston. Since BMC Software got its start here in 1980, tech companies in Houston like HPE, KBR, HighRadius and Crown Castle are now spread all over the area building great tech that even the most traditional industries can easily use. Each of these technology companies promises something different, whether that be energy-specific software or cloud-based platforms. And with 2026 almost over, it’s time to start planning your next move.

Whether you’ve made a plan to change jobs this year or not, adding a Houston tech company to your shortlist can make it simpler to get the work you want, especially with the number of growing employers in the job market today. They can also offer you room to grow. By hiring for real roles and giving you real projects to work on, these companies can make a career here less of a gamble. Or, if you’re even more short on time and are looking to hire a team next year, then you could even go with one of the IT companies in Houston that offer custom software that starts with a short, free call.

We dug into some of the top tech companies in Houston and cut it down to the 20 best.

How We Picked These Companies

  • Houston Base: These companies typically run their headquarters here. If a company is based somewhere else, you’ll want to see a staffed office that makes it easy to visit and meet the team (and isn’t just a mailing address).
  • Its Own Name: All of these companies are still running under their own names. Some of them may be owned by a bigger parent, while others might trade on the stock market. Browse each company’s newsroom to get a feel for how often things change.
  • Real Tech Work: These companies build software, hardware, data platforms or infrastructure for clients. That means you wind up with a lot of energy names and a limited number of consumer software companies. The same goes for companies that work in space tech.
  • Public Facts: These companies do make big claims about what they do, but it’s worth noting that most profiles, from a fact-checking point of view, work out to about as useful as a press release would, so we leaned on each company’s own newsroom, filings and careers pages, thus knowing where each fact comes from. Let this list jumpstart your search, but it’s not the final word for a job hunt.
  • Your Goal: There are tech companies in Houston that cater to all kinds of goals now. If you’re job hunting, investing, looking for a vendor or all of these, you’ll be able to spot a company on this list that will fit your needs (and quickly).

The 20 Best Tech Companies in Houston

1. Octal Digital

Founded: 2014 | Houston location: Energy Corridor | CEO: David Roberts

Octal Digital is a true local player in the custom software game. Its developer-built apps are made to be simple to use and easy to manage. Plus, the whole first consultation is free of charge. If you’re looking to turn a new idea into an app, Octal Digital might be a safe bet. Expect projects like iOS and Android apps and web platforms and custom software with AI integration.

2. Hewlett Packard Enterprise (HPE)

HPE, which moved its global headquarters to Spring in Greater Houston from California, is the tech company for those who can’t build their own servers, but don’t want to rent everything from the public cloud. Because the company can handle much of the setup work for you, servers can arrive racked and ready to run. Its hardware, used by big banks and research labs, comes in versions built to handle AI work. Expect products like ProLiant servers with Aruba networking and Cray supercomputers built for national labs. Check out HPE’s GreenLake cloud for pay-per-use setups made with on-site servers and cloud-style billing.

3. BMC Software

BMC Software goes deep on automation for its IT tools to keep downtime low for clients. The company uses job scheduling, fewer manual steps, mainframe tools and workflow automation so your team can focus on uptime. Its lineup isn’t flashy, staples include Control-M and its mainframe tools, but it gets the work done.

4. KBR

Most people will never work on a NASA mission in their own careers, but you can apply to KBR (soon Trinzic), which will likely be the closest thing. Today, the company works on government and energy contracts across 28+ countries. Projects use science teams and engineering crews to create unusual career combinations. The KBR project list runs the gamut in industry with work like space flight support, LNG plants and defense systems. Better yet, it’s headquartered in downtown Houston.

5. HighRadius

Rather than working a set list of invoices by hand, HighRadius users let AI agents handle much of the routine work. Users have the choice to customize their setup with treasury, accounts payable or extra helpings of automation. Past rollouts have included automated cash posting and early credit-risk alerts. It’s one of the more detailed finance software options.

6. Crown Castle

Crown Castle is a Houston-based tower company with assets like roughly 40,000 cell towers across the U.S. When renting space, carriers can choose from towers in big cities, suburbs and rural markets, and its fiber and small-cell units were sold in May 2026. Most sites can be shared by several carriers, so a fast, strong signal can end up on your phone faster than building new towers.

7. PROS

PROS prices arrive mostly worked out, so an airline can load and sell faster. PROS accommodates a wide range of airline needs, and its Kairos platform serves 140+ airlines. A sample setup may include anything from fare pricing to seat upsells. Plus, all of PROS’s travel work now runs under Thoma Bravo. Yay for fewer empty seats.

8. Intuitive Machines

If you’re all about rockets, landers and going to the Moon, then Intuitive Machines is the company for you. The company builds lunar landers and data relay satellites with a focus on NASA missions and paying customers. Roles may be open to make your career in software, hardware, flight control or test work, and all of the missions, which include the IM-1 and IM-2 landings, have been run from its Houston base.

9. Axiom Space

Axiom Space just wants to put more people in orbit, from the ground up. The company, which has flown four private crews to the space station, Ax-1 through Ax-4, has a strong focus on building its own station. Their station modules are designed by engineers and scientists to be safe, and their spacesuits are moon-bound, NASA-backed, still in testing and built for things like the Artemis landings.

10. FlightAware

Pilots and travelers can turn to FlightAware for a flight tracking service that caters to most kinds of trips. The company has data for airlines, airports and private jets, and you can even add live alerts to your phone. Users in the past have had delay warnings and gate changes sent to them. Even if you aren’t a frequent flyer, FlightAware is still a handy option for people looking for a friend’s flight.

11. Cart.com

Cart.com makes it simple for those with growing brands to sell and ship products from one place. With warehouses across the country, it offers a broad setup for the category. Despite the young age, the service options are vast and the software is solid, a bit like an online store and a warehouse in one.

12. Quorum Software

Quorum’s software plans center around flow for its energy industry customers. The company makes it simple to track production, run oil and gas accounting and plan drilling to suit your field team. Many products come with cloud-first setups, which include shared data standards. Even if you’re not in oil and gas, you can still use Quorum’s careers page for job ideas.

13. HCSS

HCSS is hoping to replace spreadsheets in your bids. The company’s aim is to make construction software easier for everyone, and it offers its estimating, fleet and job-costing tools from its Sugar Land campus. Expect solid, field-tested products like HeavyBid and HeavyJob.

14. Oceaneering

Oceaneering’s robots center around hard places, deep water, offshore rigs and defense sites, to produce work that is safe and good for clients. The company caters to various industries, and much of its work runs on remotely operated vehicles. Examples of what you can find in an Oceaneering project include work such as subsea inspection and aerospace and defense tech.

15. Enverus

Enverus’s data service caters to drillers and those with energy assets. On top of that, its data arrives cleaned, ready to be used in a model, in a report or on a map. Users can pick tools by market, where they have the option for a variety of focus areas such as oil and gas, power or renewables. Choose Enverus’s SaaS platform to get market data delivered to your team on a regular schedule. A sample workload includes jobs such as well planning, land research and power price forecasts.

16. AspenTech

Having good process software is key to having a good day at a refinery. A well-known name here is AspenTech, now part of Emerson, it works really well, and it usually finds plants a better way to run, and lets engineers know when there is a problem or slowdown and how to work around it. It also allows you to test a change in a model before trying it on the real unit. We like that it also has a Houston office, which is always important to us.

17. Cognite

Cognite is a company that helps link your plant data and models in one place. Opening a Houston office in 2019 was a big step. The software is industrial and straightforward, with enough tools to make it worth a look as an energy company. You can connect a huge number of data sources, but the nice part is that it automates a lot, so you do less manual cleaning of your sensor information. Regarding home base, Cognite moved its global headquarters from Oslo to Tempe, Arizona, with Houston as a key U.S. office at The Ion. The platform uses sensor data or information from plant systems, making it useful enough for AI tools. Overall, we think Cognite is a well-designed and focused company.

18. Microsoft

Microsoft opened a technology center in Houston with an oil and gas focus, providing an easy way to start a digital transformation, especially for energy companies. With Microsoft, customers can get Azure and Copilot from one vendor, that’s handy for big IT teams. One of the nicest things about Microsoft is that its Houston office at The Ion is close by, allowing local teams to meet in person without flying to Redmond. However, it isn’t a Houston company, and its headquarters is in Redmond, Washington. Microsoft also gives customers the freedom to choose between running Azure in the cloud or opting for a hybrid setup with places such as on-site data centers. Additionally, you can check its careers page for Houston roles.

19. Air Liquide

Air Liquide provides industrial gases without requiring a plant to make them itself before running. Air Liquide says its U.S. headquarters is in Houston, making it a solid option for many local engineers. To keep gas at the plant, Air Liquide customers get pipeline supply or on-site units and link them to their production lines. In addition, the company runs hydrogen and electronics units, so demanding customers are covered. Since Air Liquide supplies chip makers, it is a quiet link in other tech supply chains, such as electronics. By working across many industries, it can spread its tech and watch it show up in places you’d never expect.

20. DataVox

With DataVox, you can easily get help with your office network, which can help you map out your IT budget better. DataVox provides you with managed IT and cybersecurity on networks, phones, audio-visual setups, physical security, and more. You can also keep on top of security or uptime issues that may impact work. The company provides detailed help on networks and phone systems. It has been in Houston since 1990. Simply reach out through their site and you’ll get a quote.

Is Houston a Tech Hub?

Yes, and our team has worked in Houston since 2014, so we see the amount of tech work offered in any given week. Houston considers itself an energy town, but its tech scene makes it easy to find something new and unexpected often. Many of the pairings look like they would never work in a hundred years, but somehow the mix of oil, health care and space tech usually ends up working well. Our team also appreciates how Houston has steadily increased the amount of startup support it offers over the years, as The Ion and other hubs make it far less lonely than it used to be. Our only real complaint is that the scene could stand to be louder, as many people still have to look up Houston tech companies before they have the chance to apply to them.

Where Are Houston’s Tech Companies?

Most people picture downtown first, along with the big towers to choose from and good transit links. But what surprises them most is the spread of the city, with tech clusters in so many little pockets from Spring and The Woodlands to Clear Lake, and the Energy Corridor out west near Katy. But the drives between them don’t stay short as long as traffic from I-10 or the other freeways gets in the way, and few people consider the commute to be up to their usual standards. Most of all, it helps to know the seven main areas below, along with the kind of company each one is known for.

Which Houston Tech Companies Are Hiring?

Here are the Houston tech companies with careers pages you can check today:

Tech Company or IT Services Firm: Which Do You Need?

Are you interested in finding one of the IT companies in Houston to build or run tech for you? Picking the right tech partner is a big decision, so be certain that you know the difference before making a call. Choosing the wrong kind of company can make or break the outcome of your project. Here’s how to tell the three kinds apart:

Comparison of a tech company, an IT services firm and a software developer, with Houston examples
Three kinds of Houston tech partners and when to pick each one.

Tech Companies: Prior to contacting a big tech company, be sure to know what it sells. Check several companies to work out if they can sell you what you’re looking for. It’s worth it to spend a decent amount of time reading and finding a product that is the right fit. Be sure to scroll through their product pages. Look through their case studies to see if their tools line up with your needs. If the product can’t bend to your process, then how likely is it you’ll stay happy with the license that you buy? Make sure to also look at their pricing page, as this can clear up a few of your questions and save you time.

IT Services Firms: Before most IT firms take over your systems, you will have to sit through an audit or assessment session. When you sit in on an assessment, it’s important to explain exactly what you want your network to do and settle your support hours. This is often an in-person meeting that some firms will bill you for. This will often take a few hours to pull the details from your team and put them on paper so as to create a support plan for your business.

Software Development Companies: When you are picking a custom software company or one of the web development companies in Houston, ask them what their build process is. It is key to know how you will talk with them throughout the build and what the stages of the work will be. Most custom software projects can take months to finish, so make sure you pick a firm that will keep you posted on your app.

FAQs

What big tech companies are in Houston?

When you are listing big tech companies in Houston, it is imperative that you start with the ones based here. The biggest names may seem the most obvious, but know that HPE, BMC, KBR, HighRadius and Crown Castle all run their headquarters in the Houston area. Many global companies like Microsoft also run offices here to get closer to clients and then hire locally. You should also count newer, fast-growing space and ecommerce companies that can shake up the list each year. If you skip them, you may miss a big part of the scene.

Is Houston a tech hub?

It is imperative to look past the oil and gas image of Houston. What if you moved here for tech and found no jobs? It would be a letdown, but the area has thousands of tech employers, from HPE in Spring to the startups at The Ion in Midtown. Software is only one part of the scene. The tech scene that you find here should be able to offer a mix of energy tech, health tech at the Texas Medical Center and space tech around NASA’s Johnson Space Center that will help set Houston apart from Austin and Dallas.

Which tech companies have headquarters in Houston?

Many tech companies will say they are in Houston, then run the business from a headquarters somewhere else. Checking an address can be a slow job, but if you are hunting for real Houston companies, you want to make sure that the actual head office is in the area. Finding one requires a look at filings, careers pages and newsrooms working together, which is how BMC, KBR, HighRadius, Crown Castle and Oceaneering made this list.

Which tech companies are hiring in Houston?

Hiring in Houston tech is not just about coders. It is also about cloud, data and cyber roles that will ultimately keep big systems running. It’s not wise to check just one job board because the careers pages of HPE, KBR and Oceaneering are also central to your search. You need the full picture to find roles such as software, data and security work in the city.

What is the difference between an IT company and a tech company?

Information technology (IT) covers a lot more than just fixing office computers. It’s about giving staff a reliable and secure setup for the systems they use. The best tech companies are made up of builders that understand products geared toward thousands of customers at once. These are the ones, like HPE and BMC, that end up making an impact large enough to shape the market.

What are the big tech companies in Texas?

The right list of Texas tech companies will have a proven mix of names like Dell in Round Rock and AT&T and Texas Instruments in Dallas. A few specific lists, like our tech companies in Dallas and Los Angeles posts, will give you a good feel for the other markets.

How did you pick the companies on this list?

Know what kind of company that we would put on this list. Are we looking for a more global, or more local company? We looked for companies that fit well with a Houston base and a tech focus. For the list to stay useful, it’s imperative to find companies that we can check against their own sites.
