Revenue growth is on fire at Houston-based Simple Solar.

Revenue at Simple Solar, a provider of residential solar installations, soared 8,007 percent from 2019 to 2021, putting it at No. 2 among the fastest-growing private companies in the Southwest. It leads the list of 25 Houston-area companies appearing in the new Inc. 5000 Regional rankings for the Southwest.

Between 2019 and 2021, the 165 private companies on the Southwest list posted an average growth rate of 557 percent. In 2021 alone, they added 16,116 jobs and nearly $5.5 billion to the Southwest’s economy.

“This year’s Inc. 5000 Regional winners represent one of the most exceptional and exciting lists of America’s off-the-charts growth companies,” says Scott Omelianuk, editor-in-chief of Inc. magazine. “They’re disruptors and job creators, and all delivered an outsized impact on the economy. Remember their names and follow their lead. These are the companies you’ll be hearing about for years to come.”

2 leading Texas universities rank among world’s best for entrepreneurs

honor roll

The Lone Star State’s two biggest universities—the University of Texas at Austin and Texas A&M University—rank among the world’s best schools for entrepreneurs.

PitchBook’s annual list of the world’s top 100 universities for entrepreneurs takes into account both undergraduate and graduate programs. PitchBook analyzed more than 222,000 startup founders whose startups are VC-backed.

UT’s “unique” advantage

UT Austin landed at No. 10 on the list, down from No. 8 last year. PitchBook identified 1,002 UT-alumni founders at 948 startups. Collectively, those startups have raised $34.7 billion, according to PitchBook.

Among the 948 UT Austin-affiliated startups, these five have raised the most capital:

  • No. 1 Tucson, Arizona-based World View, $2.8 billion
  • No. 2 Austin-based Apptronik, $966 million
  • No. 3 Mountain View, California-based Lightmatter, $821 million
  • No. 4 Austin-based Function Health, $807 million
  • No. 5. San Francisco-based Niantic, $779 million

“The unique UT Austin advantage is the alignment between the university and the city,” Foundra.ai says. “Unlike schools where the campus ecosystem and the local startup scene are disconnected, Austin’s startup community actively recruits UT students and alumni, and UT programs actively send students into the local ecosystem.”

Texas A&M’s “living laboratory”

UT Austin’s biggest in-state rival, Texas A&M, appeared at No. 79 on the list, down from No. 76 last year. PitchBook tallied 317 A&M-alumni founders at 295 startups. Collectively, those startups have raised $9.8 billion, according to PitchBook.

Among the 317 A&M-affiliated startups, these five have raised the most capital:

  • No. 1 Austin-based RigUp, $817 million
  • No. 2 Austin-based ICON, $543 million
  • No. 3 Scottsdale, Arizona-based HomeLight, $413 million
  • No. 4 Everett, Washington-based Zap Energy, $326 million
  • No. 5 San Diego-based Splice Therapeutics, $320 million

A cornerstone of Texas A&M’s entrepreneurship offerings is the Center for Applied Entrepreneurship and Innovation at the Mays School of Business. The business school says the center “helps students explore, test, build, buy, and transform businesses in real markets.”

“Grounded in Texas as a living laboratory and guided by the Aggie core values, the center advances applied learning through industry engagement, AI-enabled experimentation, and collaboration across Mays and Texas A&M,” the business school says.

The most “exceptional” schools on PitchBook’s list

In announcing its rankings, PitchBook said: “Great entrepreneurs can come from anywhere, but some universities have a truly exceptional track record of attracting and producing future founders.”

The most exceptional universities, based on PitchBook’s criteria, are:

  • No. 1 University of California, Berkeley
  • No. 2 Stanford University
  • No. 3 Harvard University
  • No. 4 Cornell University
  • No. 5 Massachusetts Institute of Technology (MIT)

Planned KBR spinoff scores $1B NOAA deal for extreme weather forecasting

weather watch

Amid a major spinoff, Houston-based KBR's Mission Technology Solutions business has been awarded a five-year contract for up to $1.1 billion from NOAA’s National Weather Service to help predict and combat extreme weather conditions.

Under the follow-on Commercial Data Program National Mesonet Program (CDP NMP) contract, KBR will provide weather and observational data from commercial stations, university and research campuses, and other non-federal providers nationwide. The information collected will assist in predicting severe temperatures and high-impact weather conditions like extreme storms.

"This award underscores KBR's proven track record of delivering vital data that strengthens national forecasting capabilities," Todd May, KBR’s senior vice president of Mission Technology Solutions, said in a news release.

According to a separate release from NOAA, the contract expands upon KBR's existing relationship with the agency. KBR will work with about 70 private industry partners on services such as data recording, collection, aggregation and processing, and will lead the CDP NMP's "network of networks."

“NOAA gathers environmental information from a wide variety of sources, and a growing list of private industry partners have joined our agency to collect this vital data,” Ken Graham, director of NOAA’s National Weather Service, said in the release. “This agreement streamlines the process that turns raw data into the gold-standard forecasts that Americans depend on.”

KBR will utilize its Speed to Mission ImpactSM technology for the project to supply data from across regions, measurement types, and system configurations. Both KBR and NOAA say the expanded data collection contract will help the agency create more accurate and timely forecasts, particularly for severe weather and extreme events, while also creating a path for new weather-observation technologies.

KBR has supported the CDP NMP for more than 9 years. The program will be managed in Greenbelt, Maryland.

"We're driving expanded integration of commercial sensor and data sources into this platform and are honored to know our work helps forecasters give their communities earlier warnings and more time to prepare for dangerous weather,” May added in a release.

KBR’s Mission Technology Solutions business will be rebranded as Trinzic after its planned spin-off, the company announced last month. The spin-off is expected to close in January 2027.

Trinzic will work as an independent, publicly traded company focused on technology and engineering services for the space and national security sector. KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition.
