Over 200 startups participated in CERAWeek this year, and 18 of those companies pitched at a Greater Houston Partnership event.

The Houston Energy Transition Initiative, an initiative to promote Houston's work within the energy transition, hosted its second annual HETI Energy Ventures Competition at CERAWeek Innovation Agora. The competition was divided into four categories. The first batch of startups consisted of five companies from the Texas Entrepreneurship Exchange for Energy, or TEX-E, a collaboration with Greentown Labs, MIT’s Martin Trust Center for Entrepreneurship, and universities across Texas.

The winning startups shared $50,000 of prizes, sponsored by TEX-E. Houston-based Helix Earth Technologies — which has developed high-speed, high-efficiency filter systems derived from technology originating at NASA — won both the first place prize and fan favorite for the category. Helix's co-founders, Rawand Rasheed and Brad Husick from Rice University, walked away with $25,000 in prizes

Houston boasts No. 2 biggest population gain in U.S., Census data shows

Boomtown

Houston saw the second-highest population increase in the United States in 2024, according to the U.S. Census Bureau.

The new population report revealed Houston gained 43,217 residents from July 2023 to July 2024, bringing the city's population to 2,390,125.

Houston hung on to its ranking as the fourth largest city in the country and joined 11 other Southern cities that saw the largest numeric population gains in 2024, the report added.

Elsewhere in Texas, Fort Worth is now home to more than 1 million residents, surpassing Austin as the 11th largest city in the U.S. Fort Worth had the fifth-highest numeric increase in population, adding 23,442 residents during that same time frame to bring the city's total population to 1,008,106 residents.

Dallas retained its No. 9 spot on the list of the 15 most populous cities in the U.S. The city gained more than 23,000 residents during the one-year period, bringing its population to 1,326,087 people in 2024.


Austin slipped two spots and now ranks as the 13th largest city after adding more than 13,000 residents to bring the Texas Capital's population to 993,588.

San Antonio gained 23,945 residents — the fourth-highest increase nationwide — and was the only other city besides Houston to have a higher numerical growth rate than Fort Worth during the one-year period.

Fastest-growing U.S. cities
Princeton, a North Texas suburb of Dallas, topped the charts as the No. 1 fastest-growing U.S. city in 2024. The Census Bureau says the city's population has more than doubled in the last five years to more than 37,000 residents.

Fulshear, 34 miles from downtown Houston, has continued its rapid expansion as the second-fastest growing city. The suburb grew nearly 27 percent since the previous year, and its population rose to 54,629 residents as of July 2024.

Five additional Texas cities made the list of fastest-growing U.S. cities:

  • Celina, near Dallas (No. 4) with 18.2 percent growth (51,661 total population)
  • Anna, near Dallas (No. 5) with 14.6 percent growth (31,986 total population)
  • Fate, near Dallas (No. 8) with 11.4 percent growth (27,467 total population)
  • Melissa, near Dallas (No. 11) with 10 percent growth (26,194 total population)
  • Hutto, near Austin (No. 13) with 9.4 percent growth (42,661 total population)

The Austin suburb of Georgetown's growth has continued to slow down since 2023, and it no longer appears in the list of fastest-growing cities. However, it did surpass 100,000 residents in 2024. San Angelo, a small city in West Texas, also surpassed the 100,000-population threshold.

Most populous U.S. cities in 2024
New York City maintained its stronghold as the biggest in America in 2024, boasting a population of nearly 8.5 million residents. Los Angeles and Chicago also retained second and third place, with respective populations of nearly 3.88 million and more than 2.7 million residents.

"Cities in the Northeast that had experienced population declines in 2023 are now experiencing significant population growth, on average," said Crystal Delbé, a statistician in the Census Bureau’s Population Division. "In fact, cities of all sizes, in all regions, showed faster growth and larger gains than in 2023, except for small cities in the South, whose average population growth rate remained the same."

The 15 populous U.S. cities as of July 1, 2024 were:

  • No. 1 – New York, New York (8.48 million)
  • No. 2 – Los Angeles, California (3.88 million)
  • No. 3 – Chicago, Illinois (2.72 million)
  • No. 4 – Houston, Texas (2.39 million)
  • No. 5 – Phoenix, Arizona (1.67 million)
  • No. 6 – Philadelphia, Pennsylvania (1.57 million)
  • No. 7 – San Antonio, Texas (1.53 million)
  • No. 8 – San Diego, California (1.4 million)
  • No. 9 – Dallas, Texas (1.33 million)
  • No. 10 – Jacksonville, Florida (1 million)
  • No. 11 – Fort Worth, Texas (1 million)
  • No. 12 – San Jose, California (997,368)
  • No. 13 – Austin, Texas (993,588)
  • No. 14 – Charlotte, North Carolina (943,476)
  • No. 15 – Columbus, Ohio (933,263)

Houston VC firm closes $21M fund for underrepresented founders

fresh funding

Houston-based South Loop Ventures recently closed its debut fund for more than $21 million, led by investments from Rice Management Company and Chevron Technology Ventures.

The funds will go toward teams with at least one underrepresented founder of color working in the energy, health, space, sports and fintech sectors. Additional investments came from The Great Commission Foundation of the Episcopal Diocese of Texas, Texas CapitalBank and others organizations.

According to South Loop Ventures, less than 3 percent of venture capital reaches underrepresented founders of color. Zach Ellis Jr., founder and general partner of South Loop, says the firm wants to address this "billion-dollar blind spot."

"Inequitable distribution of venture capital represents a clear market inefficiency—and market inefficiencies translate into exceptional opportunities," Ellis said in a release.

He added that the firm's location in Houston will help it make an impact.

"Being anchored here gives us front-row access to world-class corporations eager to engage and support innovation from founders with underrepresented voices and perspectives," he added in the release.

Ellis founded South Loop Ventures in 2022. It has funded 13 companies since August 2023 and plans to fund several more this year. Its portfolio includes Houston-based Milkify, a breast milk freeze-drying service; Lokum App, a Houston-founded platform for recruiting certified registered nurse anesthetists; and others.

Ellis' background spans the United States Military, academia, and roles at Rev1 Ventures and PepsiCo’s corporate venture team. He previously told InnovationMap that he was called to invest in founders of color after George Floyd's murder. He says he also realized how much money was being left on the table by overlooking these innovators.

"The mission of South Loop is to become the preeminent source of venture capital dollars for underrepresented, diverse teams nationally to serve as a beacon for the best underrepresented talent and to enable them to be successful through leveraging the unique resources and talent of Houston," he said on the Houston Innovators Podcast in 2024. "A big part of our mission is also to help catalyze Houston as an ecosystem for tech entrepreneurship."

$44 million mass timber project at UH slashed energy use in first year

Building Up

The University of Houston has completed assessments on year one of the first mass timber project on campus, and the results show it has had a major impact.

Known as the Retail, Auxiliary, and Dining Center, or RAD Center, the $44 million building showed an 84 percent reduction in predicted energy use intensity, a measure of how much energy a building uses relative to its size, compared to similar buildings. Its Global Warming Potential rating, a ratio determined by the Intergovernmental Panel on Climate Change, shows a 39 percent reduction compared to the benchmark for other buildings of its type.

In comparison to similar structures, the RAD Center saved the equivalent of taking 472 gasoline-powered cars driven for one year off the road, according to architecture firm Perkins & Will.

The RAD Center was created in alignment with the AIA 2030 Commitment to carbon-neutral buildings, designed by Perkins & Will and constructed by Houston-based general contractor Turner Construction.

Perkins & Will’s work reduced the building's carbon footprint by incorporating lighter mass timber structural systems, which allowed the RAD Center to reuse the foundation, columns and beams of the building it replaced. Reused elements account for 45 percent of the RAD Center’s total mass, according to Perkins & Will.

Mass timber is considered a sustainable alternative to steel and concrete construction. The RAD Center, a 41,000-square-foot development, replaced the once popular Satellite, which was a food, retail and hangout center for students on UH’s campus near the Science & Research Building 2 and the Jack J. Valenti School of Communication.

The RAD Center uses more than 1 million pounds of timber, which can store over 650 metric tons of CO2. Aesthetically, the building complements the surrounding campus woodlands and offers students a view both inside and out.

“Spaces are designed to create a sense of serenity and calm in an ecologically-minded environment,” Diego Rozo, a senior project manager and associate principal at Perkins & Will, said in a news release. “They were conceptually inspired by the notion of ‘unleashing the senses’ – the design celebrating different sights, sounds, smells and tastes alongside the tactile nature of the timber.”

In addition to its mass timber design, the building was also part of an Energy Use Intensity (EUI) reduction effort. It features high-performance insulation and barriers, natural light to illuminate a building's interior, efficient indoor lighting fixtures, and optimized equipment, including HVAC systems.

The RAD Center officially opened Phase I in spring 2024. The third and final phase of construction is scheduled for this summer, with a planned opening set for the fall.
