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 podcast with the founder of a new venture firm, a former astronaut and recent award recipient, and a health care innovator with fresh funding.

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

Texas university's innovative 'WaterHub' will dramatically reduce usage by 40%

Sustainable Move

A major advancement in sustainability is coming to one Texas university. A new UT WaterHub at the University of Texas at Austin will be the largest facility of its kind in the U.S. and will transform how the university manages its water resources.

It's designed to work with natural processes instead of against them for water savings of an estimated 40 percent. It's slated for completion in late 2027.

The university has had an active water recovery program since the 1980s. Still, water is becoming an increasing concern in Austin. According to Texas Living Waters, a coalition of conservation groups, Texas loses enough water annually to fill Lady Bird Lake roughly 89 times over.

As Austin continues to expand and face water shortages, the region's water supply faces increased pressure. The UT WaterHub plans to address this challenge by recycling water for campus energy operations, helping preserve water resources for both the university and local communities.

The 9,600-square-foot water treatment facility will use an innovative filtration approach. To reduce reliance on expensive machinery and chemicals, the system uses plants to naturally filter water and gravity to pull it in the direction it needs to go. Used water will be gathered from a new collection point near the Darrell K Royal Texas Memorial Stadium and transported to the WaterHub, located in the heart of the engineering district. The facility's design includes a greenhouse viewable to the public, serving as an interactive learning space.

Beyond water conservation, the facility is designed to protect the university against extreme weather events like winter storms. This new initiative will create a reliable backup water supply while decreasing university water usage, and will even reduce wastewater sent to the city by up to 70 percent.

H2O Innovation, UT’s collaborator in this project, specializes in water solutions, helping organizations manage their water efficiently.

"By combining cutting-edge technology with our innovative financing approach, we’re making it easier for organizations to adopt sustainable water practices that benefit both their bottom line and the environment, paving a step forward in water positivity,” said H2O Innovation president and CEO Frédéric Dugré in a press release.

The university expects significant cost savings with this project, since it won't have to spend as much on buying water from the city or paying fees to dispose of used water. Over the next several years, this could add up to millions of dollars.

Texas female-founded companies raised more than $1 billion in 2024, VC data shows

by the numbers

Female-founded companies in Dallas-Fort Worth may rack up more funding deals and more money than those in Houston. However, Bayou City beats DFW in one key category — but just barely.

Data from PitchBook shows that in the past 16 years, female-founded companies in DFW collected $2.7 billion across 488 deals. By comparison, female-founded companies in the Houston area picked up $1.9 billion in VC through 343 deals.

Yet if you do a little math, you find that Houston ekes out an edge over DFW in per-deal values. During the period covered by the PitchBook data, the value of each of the DFW deals averaged $5.53 million. But at $5,54 million, Houston was just $6,572 ahead of DFW for average deal value.

Not surprisingly, the Austin area clobbered Houston and DFW.

During the period covered by the PitchBook data, female-founded companies in the Austin area hauled in $7.5 billion across 1,114 deals. The average value of an Austin deal: more than $6.7 million.

Historically, funding for female-established companies has lagged behind funding for male-established companies. In 2024, female-founded companies accounted for about one-fourth of all VC deals in the U.S., according to PitchBook.

PitchBook noted that in 2024, female-founded companies raised $38.8 billion, up 27 percent from the previous year, but deal count dropped 13.1 percent, meaning more VC for fewer startups. In Texas, female-founded companies brought in $1.3 billion last year via 151 deals. The total raised is the same as 2023, when Texas female founders got $1.3 billion in capital across 190 deals.

“The VC industry is still trying to find solid footing after its peak in 2021. While some progress was made for female founders in 2024, particularly in exit activity, female founders and investors still face an uphill climb,” says Annemarie Donegan, senior research analyst at PitchBook.
