The venture capital haul for Houston-area startups jumped 23 percent from 2023 to 2024, according to the latest PitchBook-NVCA Venture Monitor.

The fundraising total for startups in the region climbed from $1.49 billion in 2023 to $1.83 billion in 2024, PitchBook-NVCA Venture Monitor data shows.

Roughly half of the 2024 sum, $914.3 million, came in the fourth quarter. By comparison, Houston-area startups collected $291.3 million in VC during the fourth quarter of 2023.

Among the Houston-area startups contributing to the impressive VC total in the fourth quarter of 2024 was geothermal energy startup Fervo Energy. PitchBook attributes $634 million in fourth-quarter VC to Fervo, with fulfillment services company Cart.com at $50 million, and chemical manufacturing platform Mstack and superconducting wire manufacturer MetOx International at $40 million each.

Across the country, VC deals total $209 billion in 2024, compared with $162.2 billion in 2023. Nearly half (46 percent) of all VC funding in North America last year went to AI startups, PitchBook says. PitchBook’s lead VC analyst for the U.S., Kyle Stanford, says that AI “continues to be the story of the market.”

PitchBook forecasts a “moderately positive” 2025 for venture capital in the U.S.

“That does not mean that challenges are gone. Flat and down rounds will likely continue at higher paces than the market is accustomed to. More companies will likely shut down or fall out of the venture funding cycle,” says PitchBook. “However, both of those expectations are holdovers from 2021.”

Houston e-commerce platform expands logistics network with acquisition of fulfillment operations arm

M&A move

A Houston e-commerce unicorn has made its latest strategic acquisition.

Cart.com, which operates a multichannel commerce platform, announced that it has acquired Guthy-Renker's wholly-owned fulfillment operations arm OceanX. The terms of the deal were not disclosed. Around 200 OceanX employees will be assumed onto the Cart.com team, and the fast-growing company will add two new facilities totaling over 600,000 square feet to its network, expanding to include a West Coast distribution hub in Southern California and its third facility near Columbus, Ohio.

"Acquiring OceanX is part of Cart.com’s strategy to continue to scale our platform and capabilities across industries, leveraging our proprietary technology to improve efficiency and deliver superior results to our clients and their customers,” Omair Tariq, Cart.com founder and CEO, says in a news release. “By deploying our Constellation OMS and WMS software and seasoned operations team across these two new facilities, we will improve order visibility, labor efficiency, shipping costs and customer satisfaction for the benefit of our new clients.”

Cart.com now has 17 omnichannel fulfillment and distribution centers with around 10 million square feet and more than 1,600 team members, according to the company.

With the transition, Guthy-Renker's Co-Founder and Co-Chairman Bill Guthy will serve as a strategic adviser to Cart.com.

The move broadens Cart.com's presence in the high-volume beauty, wellness, and lifestyle industries, and the company now will work with supply chains from numerous brands, including Meaningful Beauty, The Body Firm, Smileactives, and Westmore Beauty.

“Cart.com has built a comprehensive, enterprise-grade logistics network with modern, digital capabilities that offer unparalleled visibility, control and efficiency for our brands,” Rick Odum, CEO of Guthy-Renker, says in the release. “This partnership will marry our own channel and marketing expertise with their track record of driving growth and savings for high-volume, high-SKU brands, supercharging performance across our portfolio.”

Earlier this year Cart.com secured $105 million in debt refinancing from investment manager BlackRock and a $25 million series C extension round.

In April, the company acquired an Amazon partner, Ohio-based Amify, a company that provides optimization and advertising solutions

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.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a nonprofit leader introducing new technologies, a solar tech-focused Rice University professor, and a new hire for a Houston fast-growing startup.

Generally, when children are under the age of five, educators believe that they are best suited for and interested in learning, because those are the years in which there is the strongest opportunity to build a broad and solid foundation for lifelong literacy and well-being.

That sentiment is deeply held by Collaborative for Children, the Houston-based nonprofit organization with the mission to meaningfully improve the quality of early childhood education and provide access to cutting-edge technology through its Centers of Excellence to all children, especially those in low-income and marginalized communities.

“The reason the organization was started about 40 years ago is that a group of philanthropists in the greater Houston area suggested that this was so important because 90 percent of the brain develops or grows in the time frame between ages zero to five years of age,” Melanie Johnson, president and CEO of Collaborative for Children, tells InnovationMap.

Presented on the cover of a June issue of Science, a study from Rice University engineer Aditya Mohite's lab uncovered a method to synthesize a high-efficiency perovskite solar cell, known as formamidinium lead iodide (FAPbI3), converting them into ultrastable high-quality photovoltaic films, according to a statement from Rice. Photovoltaic films convert sunlight into electricity.

The new process makes solar cells that are about 10 times more durable than traditional methods.

“Right now, we think that this is state of the art in terms of stability,” Mohite said in a statement. “Perovskite solar cells have the potential to revolutionize energy production, but achieving long-duration stability has been a significant challenge.” Read more.

United breaks ground on $177 million facility and opens tech center at IAH

off the ground

United Airlines announced new infrastructure investments at George Bush Intercontinental Airport as part of the company’s ongoing $3.5 billion investment into IAH.

United broke ground on a new $177 million Ground Service Equipment (GSE) Maintenance Facility this week that will open in 2027.

The 140,000-square-foot GSE facility will support over 1,800 ground service vehicles and with expansive repair space, shop space and storage capacity. The GSE facility will also be targeted for LEED Silver certification. United believes this will provide more resources to assist with charging batteries, fabricating metal and monitoring electronic controls with improved infrastructure and modern workspaces.

Additionally, the company opened its new $16 million Technical Operations Training Center.

The center will include specialized areas for United's growing fleet, and advanced simulation technology that includes scenario-based engine maintenance and inspection training. By 2032, the Training Center will accept delivery of new planes. This 91,000-square-foot facility will include sheet metal and composite training shops as well.

The Training Center will also house a $6.3 million Move Team Facility, which is designed to centralize United's Super Tug operations. United’s IAH Move Team manages over 15 Super Tugs across the airfield, which assist with moving hundreds of aircraft to support flight departures, remote parking areas, and Technical Operations Hangars.

The company says it plans to introduce more than 500 new aircraft into its fleet, and increase the total number of available seats per domestic departure by nearly 30%. United also hopes to reduce carbon emissions per seat and create more unionized jobs by 2026.

"With these new facilities, Ground Service Equipment Maintenance Facility and the Technical Operations Training Center, we are enhancing our ability to maintain a world-class fleet while empowering our employees with cutting-edge tools and training,” Phil Griffith, United's Vice President of Airport Operations, said in a news release. “This investment reflects our long-term vision for Houston as a critical hub for United's operations and our commitment to sustainability, efficiency, and growth."

UH study uncovers sustainable farming methods for hemp production

growth plan

A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.
