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.

Incentifind — finding green incentives for commercial and residential building

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."

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
