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."

Houston maritime startup raises $43M to electrify vessels, opens new HQ

Maritime Mission

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Innovative Houston-area hardtech startup closes $5M seed round

fresh funding

Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Fluxworks specializes in making contactless magnetic gears for use in extreme conditions, which can enhance in-space manufacturing. Its contactless design leads to less wear, debris and maintenance. Its technology is particularly suited for space applications because it does not require lubricants, which can be difficult to control at harsh temperatures and in microgravity.

The company received a grant from the Texas Space Commission last year and was one of two startups to receive the Technology in Space Prize, funded by Boeing and the Center for the Advancement of Science in Space (CASIS), in 2024. It also landed $1.2 million through the National Science Foundation's SBIR Phase II grant this fall.

Fluxworks was founded in College Station by CEO Bryton Praslicka in 2021. Praslicka moved the company to Conroe 2024.
