What do you get when you combine a city's surge in population, housing growth, and economy? For the Houston suburb of Conroe, it adds up to being America's No. 9 newest boomtown, according to a new survey from SmartAsset.

The personal finance website's just-released report analyzed more than 400 U.S. cities with populations of 65,000 or more to identify places experiencing rapid growth based on five-year changes in economic output, housing units, and labor force size.

Texas is home to the second-highest concentration of new boomtowns in America with 18 out of 75 located in the Lone Star State. Only Florida ranks higher than Texas by just one.

However, Texas nearly locked out the top five most bustling boomtowns in America. Austin suburb Georgetown topped the list, and its Central Texas neighbors New Braunfels (No. 2) and Leander (No. 4) ranked close behind. Dallas-Fort Worth mid-city Lewisville claimed the No. 5 spot. Lehi, Utah ranked in third place.

Conroe has soared in popularity as one of America's most sought-after suburbs over the last several years, boosted by its renter-friendliness and its livability among the millennial generation.

Conroe has seen a 37 percent increase in housing units from 2019 to 2024, with its labor force growing by 33 percent during that time. SmartAsset also determined that Montgomery County's economic output grew at compound annual rates of 4.9 percent.

The report says population booms and "expanding business activity" can create "visible momentum" for an up-and-coming city, but these fast changes can alter a city in ways residents may not expect.

"In recent years, some American cities stand out for attracting people, investment and development at a pace that sets them apart," the report said. "Boomtown status does not mean growth benefits everyone equally, but it does reflect a city’s expanding economic capacity and the new opportunities that come with it."

America's top 10 new boomtowns are:

  • No. 1 – Georgetown
  • No. 2 – New Braunfels
  • No. 3 – Lehi, Utah
  • No. 4 – Leander
  • No. 5 – Lewisville
  • No. 6 – Palm Coast, Florida
  • No. 7 – Nampa, Idaho
  • No. 8 – McKinney
  • No. 9 – Conroe
  • No. 10 – Frisco

Hardworking Houston suburb tops list of biggest boomtowns in Texas

growth spurt

The Houston suburb of Conroe has come a long way since Civil War veteran Isaac Conroe planted roots there in October 1881 with the purchase of a tract of land and the establishment of a sawmill.

Fast forward 140 years, and Conroe now reigns as the leading boomtown in Texas. On November 2, personal finance website SmartAsset released a study ranking Conroe as the No. 1 boomtown in the state. Even more impressive: The city ties with Meridian, Idaho, for the No. 3 spot among the nation's top boomtowns. The No. 1 city overall is Murfreesboro, Tennessee, a suburb of Nashville.

Conroe did not show up among the country's top 50 boomtowns in SmartAsset's 2019 study.

SmartAsset evaluated data for 500 of the largest U.S. cities to come up with its list of the top boomtowns. It looked at growth factors for each city such as five-year population change, average yearly growth in economic output (GDP), five-year change in number of businesses, five-year growth in housing, and August 2021 unemployment rate.

Among the 500 cities, Conroe ranks fifth for the five-year population change (26.03 percent) and fourth for the five-year growth rate in housing (39.69 percent). On SmartAsset's 100-point boomtown scale, Conroe earns a score of 97.59.

As of April 2020, Conroe was home to nearly 90,000 people, according to the U.S. Census Bureau.

"Population growth in Conroe is not slowing. The increase continues to be steady. Conroe's median age and educational attainment [are] ideal for businesses looking to locate here," Danielle Scheiner, executive director of the Conroe Economic Development Council, said in April.

Conroe is the only city in the Houston area to make the top 50 on SmartAsset's boomtown list. However, five other Texas cities did break into the top 50:

  • New Braunfels (San Antonio metro area), tied for No. 14 with Concord, North Carolina. Boomtown score: 89.83. New Braunfels appeared at No. 6 in SmartAsset's 2019 boomtown study.
  • Austin, No. 17. Boomtown score: 89.52. Austin appeared at No. 12 in SmartAsset's 2019 boomtown study.
  • Round Rock (Austin metro area), tied for No. 25 with Charleston, South Carolina. Boomtown score: 86.98. Round Rock appeared at No. 10 in SmartAsset's 2019 study.
  • Denton (Dallas-Fort Worth metro area), No. 36. Boomtown score: 83.87. Denton appeared at No. 2 in SmartAsset's 2019 boomtown study.
  • McKinney (Dallas-Fort Worth metro area), No. 39. Boomtown score: 83.59. McKinney appeared at No. 14 in SmartAsset's 2019 boomtown study.

Four Texas cities dropped out of the boomtown ranking from 2019 to 2021: Frisco, which ranked 13th two years ago; College Station, ranked 16th; Flower Mound, ranked 24th; and Allen, ranked 37th.

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

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

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
