Thousands of startups call Houston home. According to the Greater Houston Partnership's data, the Houston area added 11,700 firms between 2013 to 2018. And, if you consider Crunchbase's tally, at the end of 2018, Houston had over 1,400 tech startups on the investment tracking website's radar.

This past year, InnovationMap featured profiles on dozens of these Houston startups — from blockchain and software companies to startups with solutions in health care and oil and gas. Here are 10 that stood out throughout 2019.

Topl — a blockchain startup connecting every step of the way

For Topl, 2019 was a year of laying the groundwork. In a January 2019 article on InnovationMap, Kim Raath, president of the Houston-based blockchain company, explained that Topl's mission originated out of the fact that 60 percent of the world lives on $10 a day — and it's in the poorest regions of the world where it's the hardest to get funding for a new business.

Raath says that in her experience backpacking and volunteering all around the world she learned that banks are too overwhelmed to evaluate these potential businesses. Topl has created a technology where banks can easily generate a report on these entrepreneurs that evaluates and makes a loan or investment recommendation on the business.

"We are a generation that wants a story," she says. "We want an origin, and don't want to be fooled. And, because you might be able to reduce the cost by having this transparency, you might be able to bring down the cost on both sides."

Later that year, the company closed a 20 percent oversubscribed $700,000 seed round. With the money, Topl will be able to grow its platforms, provide better product features, and increase marketing efforts. Topl's customers are drawn to the technology because of the business efficiency the blockchain adds to their supply chain, but they are also excited about how having this technology differentiates them from their competition. Raath says she's interested in growing Topl's ability to do joint marketing campaigns with their customers.

When asked about the origin story of IncentiFind — a Houston-based startup that connects real estate developers and home builders with green construction incentives — founder Natalie Goodman doesn't mince words.

"We're a complete accident," Goodman tells InnovationMap in an interview in March. "I'm an architect. We didn't set out to have a startup."

IncentiFind's mission is to increase the amount of green developments and construction projects in the U.S. The company is equipped with a massive database of green incentives that are offered by utility, county, city, state and federal agencies. Many home builders or commercial developers don't take advantage of green incentives because they're simply not aware of them, Goodman says. Commercial developers can expect to spend around $1,500 with IncentiFind, while homeowners can expect to spend between $50 and $150.

Lazarus 3D — 3D printed organs to better train surgeons

It's pretty standard for surgeons in training to practice complicated surgeries on produce — slicing bananas open and sewing grapes back together. But for a pair of Baylor College of Medicine-educated doctors, that didn't seem like sufficient prep for working with living bodies; fruit surgery was not fruitful enough. In 2014, Drs. Jacques Zaneveld and Smriti Agrawal Zaneveld founded Lazarus3D to build a better training model — and layer by layer, they created models of abs and ribs and even hearts with a 3D printer.

"We adapted pre-existing 3D printing technology in a novel proprietary way that allows us to, overnight, build soft, silicone or hydrogel models of human anatomy," Jacques, who serves as CEO, tells InnovationMap in July. "They can be treated just like real tissue."

This year, the company grew to seven people and aims to expand even more to add to its sales and manufacturing teams. Having been funded mostly by friends and family investors, Lazarus3D plans enter its first equity round to raise $6 million, InnovationMap reported last summer.

Mental Health Match — connecting people to the right therapists

Nearly five years ago, Ryan Schwartz sat in a coffee shop in crisis mode. His mother had just died suddenly and he was struggling to find an appropriate therapist. Across the table, his friend sat making a profile on a dating app. Quickly, her endeavor was complete and she was ready to swipe right, but Schwartz was still on the hunt for mental help.

"In two minutes she could have a profile matching her with a partner potentially for the rest of her life and I was sitting there for hours and hours trying to find a therapist," he told InnovationMap in June. "I thought it should be easier to find a therapist than a life partner. That's what sent me on my journey."

That journey reached a watershed last month when Schwartz launched Mental Health Match, a website designed to pair patients with their ideal therapist. The idea gained traction as Schwartz described it to people he met and found that many said they had experienced similar difficulties in finding the right practitioner for their needs.

Grab — making ordering food at the airport easier

Most airport lines are unavoidable, but a Houston startup has cut out at least some of those lines with its mobile ordering app. Houston-based software company Grab was founded by Mark Bergsrud in 2015, who worked in senior leadership roles for almost 20 years at Continental Airlines and then United Airlines, following the merger. For Bergsrud, Grab feels like another major mobile game changer the industry experienced.

"I spent many years thinking about the travel experience and how to make it better and faster," Bergsrud told InnovationMap in July. "This feels like how mobile check in felt. There was a problem customers didn't know they had — check in wasn't that difficult anyway, but to be able to have that control, people love it."

Grab now has a presence in over 37 airports around the world, including Dallas and Austin though, ironically, not yet either of Houston's airports. Expansion is in the works for Grab, which closed a multimillion-dollar Series A round this year — London-based Collinson Group was the sole contributor.

NurseDash — An app that connects nurses to shifts

Across the country, medical facilities are short on nurses. Agencies play a role in matchmaking nurses to open shifts, but agencies charge a high percentage for placement and lack transparency, says Andy Chen, former CFO for Nobilis Health Corporation. That's why he and Jakob Kohl created their app, NurseDash in 2017. The project manager for the app is in New York, but official headquarters in Houston's Galleria area, where a staff of five works with the team spread out around the world.

Since its debut, NurseDash has attracted 40 facilities in Houston, InnovationMap reported in May, including hospitals, surgery centers, and senior living, and about 400 nurses. Chen says he isn't sure just what to call his technology yet, but compares it to the ride hailing of Uber or Lyft and calls it "a virtual bulletin board."

Syzygy — hydrogen cells battery to minimize natural gas

A Houston technology company is doing something that, for many decades, wasn't thought to be possible. Syzygy Plasmonics is creating a hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions. The hydrogen-fueled technology originated out of research done over two decades by two Rice University professors, Naomi Halas and Peter Nordlander.

Syzygy's technology, CEO Trevor Best told InnovationMap in August, is structured more like a battery than that of a combustion engine. Inside the technology, there are cells, lights, and mirrors making as bright as possible, which then spurs a reaction that creates energy. It has the potential to be cheaper — it's made with cheaper materials — and, of course, cleaner than traditional fueling technology with fewer carbon emissions released.

This new photocatalytic chemical reactor has the potential to shake up the industrial gas, chemical, and energy industries — something that hasn't gone unnoticed by investors. Syzygy just closed a $5.8 million Series A round, and the funds will allow for Syzygy to continue to develop its technology and grow its team. Best tells InnovationMap that he expects to launch a full-size pilot by the end of 2020 and is already in talks with potential clients who are interested in the technology for industrial purposes.

Volumetric — 3D printed human tissue

There may come a time when you or someone you love is in need of a new pair of lungs. Or perhaps it's a liver. It's not a scenario anyone dreams of, but thanks to Houston company Volumetric, you may never end up on a waiting list. Instead, that organ is made to order and 3D printed using a mix of medical plastics and human cells.

And this possibility isn't necessarily in the distant future. On the cover of the May 3 issue of the journal Science, is a contraption that looks a bit like a futuristic beehive. It's a working air sac complete with blood vessels, the beginnings of a technology that is perhaps only a decade from being implanted in humans. And it was crafted on a 3D printer in Jordan Miller's lab at Rice University. Miller and his bioengineering graduate student Bagrat Grigoryan are primed to profit from their inventions.

In 2018, they started Volumetric Inc., a company that sells both the hydrogel solutions used for printing organs like theirs and the printers themselves. Touring Miller's lab in the Houston Medical Center is a visual timeline of his team's progress designing printers. The version being manufactured is a slick little number, small enough to fit under chemical exhaust hoods, but fitted with everything necessary to print living tissues. It's made and sold in cooperation with CellInk, a larger bioprinting company.

"Our technology is based on projection," Miller told InnovationMap in May. Specifically, it's stereolithography, a type of 3D printing that produces the finished product layer-by-layer. Shining colored light of the right intensity turns the polymers into a solid gel.

Voyager — Email-less communication tool for maritime shipping

Houston software startup Voyager is making waves in its quest to improve efficiency — and stem billions of dollars in losses — in the maritime bulk-shipping business. Now, it's got some fresh capital to help it achieve that mission.

InnovationMap reported in August that Houston-based Voyager revealed it secured $1.5 million in seed funding from four investors from around the world: Austin-based ATX Venture Partners, Houston- and California-based Blue Bear Capital, New York City-based GreenHawk Capital, and Oman-based Phaze Ventures. Previous investors include Boulder, Colorado-based Techstars and Spring-based Knightsgate Ventures.

With its software-as-a-service offering, Voyager aims to modernize the workflows of operators in the maritime bulk-commodities industry. The company says its technology will become more vital as autonomous shipping and internet- and Internet of Things-enabled cargo vessels grow in popularity. Voyager's technology enables all communication tied to a shipment to be handled via its web dashboard and app, essentially creating a one-stop shop for people who need to track messages about maritime bulk shipments.

"With Voyager, what it allows companies to do is essentially have all of those counter parties working together in a shared environment to manage the voyage together — entirely email free," Matthew Costello, CEO, tells InnovationMap in December.

Galen Data — cloud-based platform for connecting medical devices to the internet

Educated as an engineer, Chris DuPont has stepped outside his professional comfort zone to generate funding for his Houston-based startup, Galen Data Inc. DuPont's pool of technical contacts in Houston is "wide and deep," he says, but his pool of financial contacts had been shallow.

Overcoming obstacles in Houston's business waters, DuPont has raised two rounds of angel funding — he declines to say how much — that have enabled Galen Data to develop and market its cloud-based platform for connecting medical devices to the internet, including pacemakers and glucose monitors. DuPont is the startup's co-founder and CEO.

Galen Data's patent-pending technology lets medical device manufacturers tailor the cloud-based software to their unique needs. DuPont says his company's software is geared toward medical devices that are outside, not inside, hospitals and other healthcare facilities. He declines to divulge how many customers the startup has.

Hatched within Houston-based Tietronix Software Inc., DuPont's previous employer, Galen Data launched in 2016 but didn't roll out its first product until 2018. Galen Data's emergence comes as the market for internet-connected mobile health apps keeps growing. One forecast envisions the global space for mobile health exceeding $94 billion by 2023.

"We want to be at the forefront of that technology curve," DuPont tells InnovationMap in May. "We might be six months early, we might be a year early, but it's starting to happen."

Venus Aerospace closes $91 million Series B to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

  • Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
  • Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
  • Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

Condenser test in AustinSo, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

Portable bag contents

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
