Let's take a look at where you could land a job at one of Houston's top startups.

Double-digit growth

When submitting their applications for the 2024 Houston Innovation Awards, every startup was asked if it was hiring. Four Houston startups replied that they are growing their teams rapidly.

Houston e-commerce startup Cart.com, one of the city's few $1 billion-plus “unicorns," reported that it is hiring approximately 50 new employees. The company, which focuses on commerce and logistics software development, secured $105 million in debt refinancing from investment manager BlackRock this summer following a $25 million series C extension round that brought Cart.com’s Series C total to $85 million. It currently has about 1,500 employees and 4 offices in three companies since it was founded in 2020, according to its website.

Houston energy tech company Enovate Ai (previously known as Enovate Upstream) reported that it is hiring 10-plus positions. The company, with 35 current employees, helps automate business and operational processes for decarbonization and energy optimization. Its CEO and founder, Camilo Mejia, sat down for an interview with InnovationMap in 2020. Click here to read the Q&A.

Square Robot is hiring about 10 new Houston employees and 15 total between Houston and other markets, according to its application. The advanced robotics company was founded in Boston in 2016 and opened its Houston office in August 2019. It develops submersible robots for the energy industry, specifically for storage tank inspections and eliminating the need for humans to enter dangerous and toxic environments. Last year it reported to be hiring 10 to 30 employees as well, ahead of the 2023 Houston Innovators Award. It currently has 25 Houston employees and about 50 nationally.

InnoVent Renewables LLC is also hiring 15 new employees to be based in Mexico. The company launched last year with its proprietary continuous pyrolysis technology that can convert waste tires, plastics, and biomass into fuels and chemicals. The company scaled up in 2022 and has operations in Pune, India, and Monterrey, Mexico, with plans for aggressive growth across North America and Latin America. It has 20 employees in Mexico and one in Houston currently.

Senior roles

Geothermal energy startup Sage Geosystems reported that it is looking to fill two senior roles in the company. It also said it anticipates further staff growth after its first commercial energy storage facility is commissioned at the end of the year in the San Antonio metro area. The company also recently expanded its partnership with the United States Department of Defense's Defense Innovation Unit and announced this month that it was selected to conduct geothermal project development initiatives at Naval Air Station in Corpus Christi. It has 12 full-time employees, according to its application.

Steady growth

Other companies reported that they are hiring a handful of new workers, which for some will increase headcount by about 50 percent to 100 percent.

Allterum Therapeutics reported that it is adding six employees to its current team of 13. The biopharmaceutical company that is under the Fannin Partners portfolio of med tech companies was awarded a $12 million product development grant from the Cancer Prevention and Research Institute of Texas this spring.

Dauntless XR will add between five and eight employees, according to its application. It currently has four employees. The augmented reality software company, originally founded as Future Sight AR in 2018, recently secured a NASA contract for space weather technology after rebranding and pivoting. The company's CEO, Lori-Lee Elliott, recently sat down with the Houston Innovators Podcast. Click here to hear the interview.

Syzygy Plasmonics is hiring four positions to add to its team of 120. The company was named to Fast Company's energy innovation list earlier this year.

Venus Aerospace is adding five to 10 key hires to its team of 72. Andrew Duggleby founded the company with his wife and CEO Sassie in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round, and it successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with the Defense Advanced Research Projects Agency, or DARPA, earlier this year.

​Seeking selectively

Other finalists are adding to their teams with a handful of new hires of contract gigs.

​Future roles

Other finalists reported that they are currently not hiring, but had plans to in the near future.

NanoTech Materials Inc., which recently moved to a new facility, is not currently. Hiring but said it plans with new funding during its series B.

Renewable energy startup CLS Wind is not hiring at this time but reported that it plans to when the company closes funding in late 2024.

5 Houston energy tech companies named to Rice accelerator

seeing green

The Rice Alliance for Technology and Entrepreneurship has announced the 17 companies joining its second accelerator — and the program didn't have to venture very far for some of them.

The Rice Alliance Clean Energy Accelerator named the early- to mid-stage startups that will participate in its second annual class — five of which are based in Houston:

  • CLS Wind is developing a unique system to lift any size wind turbine component to any height using smaller-capacity cranes, an efficient, safe and economical solution to a lack of available high-capacity cranes and vessels.
  • Dsider is developing a low code solution for climate minded organizations to visualize and analyze their carbon pathways to plan, prioritize and operate sustainably and economically.
  • Emission Critical is developing carbon accounting and management software as a service to help enterprises solve end-to-end carbon footprinting with minimum effort
  • NanoTech is developing advanced materials to help businesses and individuals solve fireproofing and thermal insulation challenges with new world particles.
  • Pressure Corp is developing waste pressure power systems to help midstream gas companies solve how they reduce emissions by providing the technology, capital and expertise required to achieve their environmental, social and governance goals.

The 10-week program kicks off at the university’s Rice Alliance Energy Tech Venture Forum in September, and concludes on Demo Day on Nov. 17. While mostly virtual, the program will welcome the complete cohort to Houston three times throughout the accelerator.

The full cohort of companies — which come from seven states and four countries — has already collectively raised more than $54.5 million. Over the 10 weeks, the companies will receive support and mentorship to help them raise funding, launch pilots, win adoption into the marketplace, and more.

The 2022 cohort specializes across the spectrum of clean energy, including advanced materials, digital technology for energy, energy efficiency, energy storage, geothermal energy, hydrogen, waste heat to power, wave energy, and wind energy. The rest of the cohort includes:

  • Atargis Energy, based in Colorado, is developing an innovative twin hydrofoil-based wave energy converter technology combined with a proprietary feedback control system that combines real-time sensors, predictive algorithms and machine learning to make possible the first predictable, low-cost, utility-scale baseload electricity sourced from ocean waves for utilities and other electricity providers.
  • Based in Somerville, Massachusetts, Eden GeoPower Inc. is developing electrical reservoir stimulation technology to help geothermal, petroleum and mineral resource developers solve issues with low-permeability reservoirs by effectively increasing permeability in a way that uses less water and emits less CO2 than traditional stimulation methods.
  • FuelX has developed solid-state hydrogen power systems to help transportation manufacturers meet their customers’ growing performance requirements by using high-energy-density systems that outperform batteries and other pure hydrogen solutions. When coupled with a green hydrogen raw material, FuelX systems provide zero-carbon power.
  • GeoGen Technologies — a Canadian company — is developing a new kind of geothermal that allows oil and gas companies to convert end of life oil and gas wells to economic geothermal.
  • Durham, North Carolina-based GOLeafe uses organic materials and non-energy or capital-intensive equipment to produce graphene oxide — the world's strongest, thinnest and most conductive material — through a process that’s 10 times more cost efficient and eco-friendly using readily available materials such as hay, sugar and wood chips.
  • LiNa Energy is commercializing safe, sustainable, solid-state sodium batteries that contain no lithium or cobalt.
  • Luminescent, based in the United Kingdom, is building an isothermal expansion heat engine for waste heat recovery along gas transmission pipelines.
  • Nobel improves fuel efficiency for gas-fired power plants with drop in, reliable supersonic combustion technology.
  • Quino Energy — based in California — produces low-cost, long-lifetime aqueous organic flow batteries for grid storage applications. The charge is stored in specially designed organic molecules called quinones, which are produced from cheap chemical precursors in a proprietary, zero-waste process.
  • Viridly, based in Texas, is developing geothermal power plants with patent-pending generator technology alongside geothermal greenhouses to provide the first financially viable way to confidently deliver and scale up the development of baseload geothermal electricity.
  • Another Canadian company, Volta Technique’s compressed air storage and management technology addresses the unpredictable and ever-increasing cost of energy for large commercial and industrial electricity users while enabling decarbonization of the electricity grid through higher integration of renewable energy.
  • Wootz, another Texas company, is developing a scalable manufacturing process to produce sustainable, cost-effective, high-performance carbon nanotube materials at commercial scale to replace or enhance traditional metallic conductors.

Twelve companies participated in Class 1 of the Rice Alliance Clean Energy, which was delivered virtually last summer. The 12 startups in that inaugural class have raised a combined $6.5 million in funding, identified and launched pilots, met investors, hired staff and moved their offices to Houston.

The program is supported by founding sponsor Wells Fargo and supporters: BP, Baker Botts, Chevron, ExxonMobil, Halliburton Labs, Equinor, Microsoft, NRG, Saudi Aramco Energy Ventures, Shell Ventures, Sunnova, TotalEnergies, Tudor Pickering Holt, Canadian Consulate, TC Energy, Phillips 66, and ENI Next.

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.

Meet 6 mentors guiding Houston’s next generation of startup founders

meet the finalists

Houston’s thriving startup ecosystem is supported by a network of experienced leaders who work behind the scenes, investing their time and knowledge to help the next generation of entrepreneurs succeed.

As part of the 2026 Houston Innovation Awards, the Mentor of the Year category will honor an individual who dedicates their time and expertise to guide and support budding entrepreneurs. They support promising startups in the medical tech, digital health, clean energy, hardware sectors and more.

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

Al Danto, Rice University

Al Danto is a senior lecturer in entrepreneurship at Rice University. He mentors undergraduate and graduate students at Rice and through the university's Liu Idea Lab for Innovation and Entrepreneurship (Lillie). He's also involved in the Houston Entrepreneurs Organization and Rice Veterans' Business Battle.

"[Mentoring] is very rewarding and fulfilling," Danto says. "[It] helps to me to pay back full circle over the incredible mentors I have had."

Eric Rubenstein, New Climate Ventures

Eric Rubenstein is managing partner at New Climate Ventures. He mentors startups through the clean energy-focused early-stage VC firm and also through the Breakthrough Energy Fellowship, Activate, Greentown Labs and Yale Ventures. Rubenstein has worked with numerous startups and Innovation Awards finalists, including Solidec, Rheom Materials, Bairitone Health, Pattern Materials and many others.

"Being a mentor is an important part of an innovation ecosystem," Rubenstein says. "Seeing founders succeed is rewarding, particularly if what they are building will meaningfully contribute to society. It is a way to give back that also builds community, as mentorship often involves introducing founders to other mentors, to potential investors and to potential customers. Just like the adage 'it takes a village' is used in reference to raising a child, the same adage applies to building a startup. That’s why we say 'let’s build.' Let’s build is inclusive because we do it together, as a community, even if the founders need to execute on a daily basis to make their vision a reality."

Jeremy Pitts, Activate

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston in 2024. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Mentorship to me is all about selflessly supporting a person," Pitts says. "The person comes first--if you're not supporting the person, then their business needs don't matter. I'm there not to answer questions for people, but to help them gain the confidence and the capability to solve problems on their own. I am successful when my mentees are successful and happy, regardless of what their personal definition of success might look like."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard. He founded Startup Circle Houston and co-hosts Cybersecurity Circle, which both meet regularly at The Ion. He participates in Mercury Fund Day and has also mentored through Impact Hub Houston. He's worked with founders of FlowCare, Unytag, STEAM OnDemand, Lokum and many other early-stage startups.

"I compare being a mentor for startup founders to the Montessori method. ... Mentoring should not involve telling a founder what to do," Alapat says. "I see it as a founder whisperer approach that seeks to challenge the founder to think through their journey through different lenses and go on a journey of self-discovery while discovering the true market pain they are seeking to solve. The cherry on top is that the mentor gains as much as the mentee, so learning is happening for both. Ultimately, the meter of achievement with mentoring is seeing visible progress with the maturity of the founder and the degree of traction for their startup."

Kyle Judah, Rice University's Liu Idea Lab for Innovation & Entrepreneurship

Kyle Judah is the executive director of Lilie, where he mentors pre-seed student startups. He also mentors through organizations like TEX-E, Greentown Labs, Activate and previously with MassChallenge. Some of the startups he's mentored include Helix Earth Technologies, Tierra Climate, Solidec, HexaSpec, SteerBio and many others.

"[Being a mentor] means helping to ensure that the most people possible have the best shot possible at making their company a successful reality," Judah says. "It means, at its root, opening the aperture for what is possible for people, by believing in them before anyone else even understands what their ambitions are. Because belief is the most infectious thing in the world. And before digging into the work in the trenches, most times founders need to kickstart their journey by having someone from the outside believe in them, when there's no real evidence to support that belief. So I guess, mentorship is a pure form of entrepreneurial faith."

Rachel Bickham, Bickham Services Unlimited LLC

Rachel Bickham is CEO of Bickham Services Unlimited, through which she mentors founders across a range of business stages and industries. She founded the organization in 2017. Bickham also mentors through The Affirmed Entrepreneur, a mentorship platform that she also launched. In 2024, she also began mentoring through the Goldman Sachs One Million Black Women: Black in Business program. Some of the startups she has worked with included Elaine Transportation, Nakira's World and NP Skills Made Easy, among others.

"Being a mentor means helping someone see what is possible while being honest about what it will take to get there," Bickham says. "It is not about giving generic advice or telling entrepreneurs what they want to hear. Sometimes mentorship means offering encouragement, and sometimes it means asking difficult questions that help someone avoid an expensive mistake. In both situations, my responsibility is to listen, share what I have learned, and help the entrepreneur make an informed decision. ... Being a mentor also means opening doors when I can—making introductions, inviting entrepreneurs into rooms they may not have entered on their own, and helping them build relationships that can change the direction of their businesses. It also means holding them accountable for what they said they wanted to accomplish. I do not measure successful mentorship by how often someone returns to me for an answer. I measure it by whether they become more confident, more strategic, and better equipped to make decisions on their own."

3 Houston incubators and accelerators fueling the growth of local startups

Meet the finalists

It takes a village to launch a business. That's where Houston's network of incubators and accelerators can step in, providing the resources, mentorship and community needed to push a fledgling company forward.

As part of our 2026 Houston Innovation Awards, the Incubator/Accelerator of the Year category honors a local organization that is championing and fueling the growth of Houston startups.

Three incubators and accelerators have been named finalists for the 2026 award. They support startups ranging from hard-tech companies to food and youth concepts.

Read more about these organizations below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced in 2024, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its third Houston cohort this summer.

The two-year program graduated its first class of Houston fellows in 2026 and saw its first alumni IPO from Houston-based Fervo Energy, which previously participated in a Berkley cohort. Nationally, it has supported 346 fellows and 276 companies since 2015. Those companies have raised more than $6 billion in follow-on funding, according to Activate. In Houston, it has supported Houston startups like Solidec, FlowCellutions and Orbital Arc. Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with members spanning 72 countries. Launched in 2018, Impact Hub Houston says its membership tripled by the beginning of 2026. This year brought major milestones for the community, including the launch of its Ideas to Impact Accelerator, which supported 11 founders across the health, education, food systems, civic technology and workforce development sectors. It also received funding from more than 20 international Impact Hubs to develop SYNC, a collaboration platform that 25 Impact Hubs across five continents have committed to pilot. The organization has worked with local startups including Myoviva Health, The Change Lab and INNERVERSE Inc.

MarMo Innovation

Galveston-based business incubator MarMo Innovation is focused on removing barriers to entrepreneurship. It aims to provide affordable space, education, mentorship, market access, connections and real-world opportunities that help entrepreneurs move from idea to launch to sustainable growth. The "industry-agnostic" incubator was founded in 2022 and is led by Executive Director Erica Delgadillo.

This year, the organization moved from primarily serving as a coworking and community space into a more comprehensive entrepreneurial incubator by expanding its MarMo Market, MarMo Market Jr. and Lunch LineUp programs. A major focus for MarMo is food entrepreneurship. It is developing an Incubator Kitchen, which MarMo says will support programs like its Cottage to Commercial Bootcamp and Food Biz 101. The organization also expanded its board this year and says it is diversifying its revenue through memberships, events, markets, equipment and space rentals, sponsorships, grants and new entrepreneurial programming.
