Houston-based Cemvita Factory is unlike most startups. Before even knowing what industry they were going to affect, Moji Karimi and his sister, Tara, established their company, which uses synthetic photosynthesis — the process of turning carbon dioxide into glucose for plants.

"In some ways, this company started with the solution, rather than the problem," Moji Karimi, co-founder of Cemvita, says. "Then we said, 'if we could replicate photosynthesis, what problems can we solve?'"

Once the technology was set in place, Karimi, who has a background in oil and gas drilling, says he identified the energy industry in need of something like this. He says he saw an increased pressure on large energy companies to adapt sustainable ways to get rid of the CO2 that is produced as a result of drilling.

More and more companies are investing in a process called carbon dioxide capturing — but it's expensive and not yet cost efficient for energy companies to commit to. But that's changing. Karimi says the process that once cost $600 per ton of CO2 now can be found as cheap as $30.

With his sister's technology, Karimi says they can take that captured carbon dioxide and turn it into other chemicals too. Each oil and gas company client can specify what they want to turn it into and, for less than $100,000, Cemvita will run a pilot program for them. Cemvita sells the exclusive rights to the technology, but still maintains its IP.

"We go to these companies and say, 'What do you want to convert CO2 into?,'" Karimi says. "Then, we do a quick pilot in six months in our lab, and we show them the metrics. They decide if they want to scale it up."

What seemed like another obvious industry for this process was aerospace. Many companies involved in aerospace exploration have Mars on the mind, and the planet's atmosphere is over 95 percent carbon dioxide. Plus, Cemvita can provide a more sustainable way to dispose of CO2 onboard spacecrafts. The current practice is essentially just discarding it by filtering it off the spaceship.

Putting a system in place
Cemvita was founded in August of 2017 and used 2018 to really establish itself. The company took second place at Dubai's Mohammed bin Rashid Space Centre Innovation Challenge and completed the accelerator program at Capital Factory.

Realizing the process is new and without the backing of an educational institution, Karimi says he and his sister needed a way to answer any questions and concerns, so Tara wrote a book. "Molecular Mechanisms of Autonomy in Biological Systems" is published by Springer.

Karimi also lead a talk at Tudor Pickering Holt's Energy Disruptor conference. His discussion, "From Mars to Midland," garnered a lot of interest from energy professionals.

The future is now
Karimi says 2019 is all about execution. He never thought he and his sister would overlap their industries, but now there's more of a need of interdisciplinary collaboration than ever before.

"There are a lot of opportunities bringing a proven science or technology from one industry into another to solve problems," he says.

The company has growth plans this year. The team has bootstrapped everything financially so far, but is looking for its first funding round in the middle of 2019. And, as far as the Karimi siblings are concerned, they are in the exact right place to grow.

"We're in Houston, and we have a technology that is from biotech and have applications in the space industry and the energy industry," Karimi says. "There would not have been any better place for us in the country than Houston."

Texas ranks among 10 best states to find a job, says new report

jobs report

If you’re hunting for a job in Texas amid a tough employment market, you stand a better chance of landing it here than you might in other states.

A new ranking by personal finance website WalletHub of the best states for jobs puts Texas at No. 7. The Lone Star State lands at No. 2 in the economic environment category and No. 18 in the job market category.

Massachusetts tops the list, and West Virginia appears at the bottom.

To determine the most attractive states for employment, WalletHub compared the 50 states across 34 key indicators of economic health and job market strength. Ranking factors included employment growth, median annual income, and average commute time.

“Living in one of the best states for jobs can provide stable conditions for the long term, helping you ride out the fluctuations that the economy will experience in the future,” WalletHub analyst Chip Lupo says.

In September, Gov. Greg Abbott announced Texas led the U.S. in job creation with the addition of 195,600 jobs over the past 12 months.

“Texas is America’s jobs leader,” Abbott says. “With the best business climate in the nation and a skilled and growing labor force, Texas is where businesses invest, jobs grow, and families thrive. Texas will continue to cut red tape and invest in businesses large and small to spur the economic growth of communities across our great state.”

While Abbott proclaims Texas is “America’s jobs leader,” the state’s level of job creation has recently slowed. In June, the Federal Reserve Bank of Dallas noted that the state’s year-to-date job growth rate had dipped to 1.8 percent, and that even slower job growth was expected in the second half of this year.

The August unemployment rate in Texas stood at 4.1 percent, according to the Texas Workforce Commission. Throughout 2025, the monthly rate in Texas has been either four percent or 4.1 percent.

By comparison, the U.S. unemployment rate in August was 4.3 percent, according to the U.S. Bureau of Labor Statistics. In 2025, the monthly rate for the U.S. has ranged from 4 percent to 4.3 percent.

Here’s a rundown of the August unemployment rates in Texas’ four biggest metro areas:

  • Austin — 3.9 percent
  • Dallas-Fort Worth — 4.4 percent
  • Houston — 5 percent
  • San Antonio — 4.4 percent

Unemployment rates have remained steady this year despite layoffs and hiring freezes driven by economic uncertainty. However, the number of U.S. workers who’ve been without a job for at least 27 weeks has risen by 385,000 this year, the Bureau of Labor Statistics reported in August. That month, long-term unemployed workers accounted for about one-fourth of all unemployed workers.

An August survey by the Federal Reserve Bank of New York showed a record-low 44.9 percent of Americans were confident about finding a job if they lost their current one.
