Conroe-based Hertha Metals, a producer of substantial steel, hauled in more than $17 million in venture capital from Khosla Ventures, Breakthrough Energy Fellows, Pear VC, Clean Energy Ventures and other investors.

The money was put toward the construction and the launch of its 1-metric-ton-per-day pilot plant in Conroe, where its breakthrough in steelmaking has been undergoing tests. The company uses a single-step process that it claims is cheaper, more energy-efficient and equally as scalable as conventional steelmaking methods. The plant is fueled by natural gas or hydrogen.

The company, founded in 2022, plans to break ground early this year on a new plant. The facility will be able to produce more than 9,000 metric tons of steel per year. Continue reading.

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 three innovators across Houston's energy transition.

Bobby Tudor, board chair of Greentown Labs

Greentown Labs, a climatetech incubator with locations in the Houston and Boston areas, has announced it has received $4 million in funding from both of the Houston and Massachusetts locations. Houston investors included Bobby Tudor, CEO of Artemis Energy Partners and chairman of the Houston Energy Transition Initiative, who also joins the organization as board chair.

“The challenges of the energy transition are immense, and the role played by technology incubators like Greentown Labs is essential,” Tudor says in a news release. “We believe this role, which is a partnership between academia, industry, philanthropists, entrepreneurs, and governments, is the best way to get to effective, scalable solutions in a time frame that the urgency of the challenge requires. We need all hands on deck, and this partnership between Massachusetts and Texas can be a role model for others.” Read more.

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced.

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.” Read more.

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.

Other Texas cities that earned spots on the list include Fort Worth (No. 13), Corpus Christi (No. 14), Arlington (No. 15), Plano (No. 17), Laredo (No. 22), Garland (No. 24), El Paso (No. 43), Lubbock (No. 46), and San Antonio (No. 61).

Data for this study was sourced from the U.S. Census Bureau, Bureau of Labor Statistics, U.S. Travel Association, Gallup, Social Science Research Council, and the Corporation for National & Community Service as of January 29, 2026.

With boost from Houston, Texas is the No. 1 state for economic development

governor's cup

Texas is on a 14-year winning streak as the top state for attracting job-creating business location and expansion projects.

Once again, Texas has claimed Site Selection magazine’s Governor’s Cup. This year’s honor recognizes the state with the highest number of economic development projects in 2025. Texas landed more than 1,400 projects last year.

Ron Starner, executive vice president of Site Selection, calls Texas “a dynasty in economic development.”

Among metro areas, Houston lands at No. 2 for the most economic development projects secured last year (590), behind No. 1 Chicago and ahead of No. 3 Dallas-Fort Worth.

In praising Houston as a project magnet, Gov. Greg Abbott cites the November announcement by pharmaceutical giant Lilly that it’s building a $6.5 billion manufacturing plant at Houston’s Generation Park.

“Growth in the Greater Houston region is a great benefit to our state’s economy, a major location for foreign direct investment and key industry sectors like energy, aerospace, advanced manufacturing, and life sciences,” Abbott tells Site Selection. “Houston is also home to one of the largest concentrations of U.S. headquarters for companies from around the world.”

In 2025, Fortune ranked Houston as the U.S. city with the third-highest number of Fortune 500 headquarters (26).

Texas retained the Governor’s Cup by gaining over 1,400 business location and expansion projects last year, representing more than $75 billion in capital investments and producing more than 42,000 new jobs.

Site Selection says Texas’ project count for 2025 handily beat second-place Illinois (680 projects) and third-place Ohio (467 projects). Texas’ number for 2025 represented 18% of all qualifying U.S. projects tracked by Site Selection.

“You can see that we are on a trajectory to ensure our economic diversification is going to inoculate us in good times, as well as bad times, to ensure our economy is still going to grow, still create new jobs, prosperity, and opportunities for Texans going forward,” Abbott says.

Houston e-commerce giant Cart.com raises $180M, surpasses $1B in funding

fresh funding

Editor's note: This article has been updated to clarify information about Cart.com's investors.

Houston-based commerce and logistics platform Cart.com has raised $180 million in growth capital from private equity firm Springcoast Partners, pushing the startup past the $1 billion funding mark since its founding in 2020.

Cart.com says it will use the capital to scale its logistics network, expand AI capabilities and develop workflow automation tools.

“This investment will strengthen our balance sheet and provide us with the flexibility to accelerate our strategic priorities,” Omair Tariq, CEO of Cart.com, said in a news release. “We’ve built a platform that combines commerce software with a scaled logistics network, and we’re just getting started.”

In conjunction with the funding, Springcoast executive-in-residence Russell Klein has been appointed to Cart.com’s board of directors. Before joining Springcoast, he was chief commercial officer at Austin-based Commerce.com (Nasdaq: CMRC). Klein co-led Commerce.com’s IPO, led the company’s mergers-and-acquisitions strategy and played a key role in several funding rounds.

“The team at Cart.com has demonstrated excellence in their ability to scale efficiently while continuing to innovate,” Klein said. “I’m excited to join the board and support the company as it expands its AI-driven capabilities, deepens enterprise relationships, and further strengthens its position as a category-defining commerce and fulfillment platform.”

Before this funding round, Cart.com had raised $872 million in venture capital and reached a valuation of about $1.6 billion, according to CB Insights. With the new funding, the startup has collected over $1 billion in just six years.
