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."

Houston logistics SaaS innovator is making waves with expanded maritime shipping platform

Houston Innovators Podcast episode 243

For several years now, Matthew Costello has been navigating the maritime shipping industry looking for problems to solve for customers with his company, Voyager Portal.

Initially, that meant designing a software platform to enhance communications and organization of the many massive and intricate global shipments happening every day. Founded in 2018 by Costello and COO Bret Smart, Voyager Portal became a integral tool for the industry that helps users manage the full lifecycle of their voyages — from planning to delivery.

"The software landscape has changed tremendously in the maritime space. Back in 2018, we were one of a small handful of technology startups in this space," Costello, who serves as CEO of Voyager, says on the Houston Innovators Podcast. "Now that's changed. ... There's really a huge wave of innovation happening in maritime right now."


Riding that wave means continuing to evolve the Voyager platform with new cost-saving, inefficiency-reducing technology. One of the industry's biggest pain points is demurrage — charges associated with delays in loading and unloading cargo within maritime shipping. Costello estimates that the total paid globally in demurrage fees is around $10 billion to $20 billion a year.

"These fees can be huge," Costello says. "What technology has really enabled with this problem of demurrage is helping companies drill down to the true root cause of what something is happening."

All this progress is thanks to the enhancement — and wider range of acceptance — of data analysis and artificial intelligence.

Costello, who says Voyager has been improving its profitability every quarter for the last year, has grown the business to around 40 employees in its headquarters of Houston and three remote offices in Brazil, London, and Singapore. The company's last round of funding was a series A in 2021. Costello says the next round, if needed, would be next year.

In the meantime, Voyager is laser focused on providing optimized, cost-saving, and sustainable solutions for its customers — around half of which are headquartered or have a significant presence in Houston. For Costello, that's all about putting the control back into the hands of his customers.

"If we think back to the real problems the industry faces, a lot of them are controlled by different groups and parties. The fact that a ship cannot get in and out of a port quickly is not necessarily a function of one party's issue — it's a multitude of issues, and there's no one factor," Costello says on the show. "To really make the whole process efficient end-to-end you need to provide the customer to access and options for different means of getting cargo from A to B — and you need to have a sense of control in that process."

Houston-based energy logistics software prepares to hire, raise funds as it scales up

now hiring

Many startups turn to offshore outsourcing to fuel their growth. The Now Network, a Houston-based energy tech startup, is doing just the opposite — relying on stateside in-sourcing.

The SaaS company is in the midst of building out its in-house development team, including full stack developers and UX/UI designers. This year, The Now Network plans to add another four to six developers, on top of the six who already are on board. Stacey McCroskey, the company's director of product since September 2019, leads the team.

Previously, the development team consisted of more than a dozen contract workers in Ukraine and India, says Mush Khan, president of The Now Network. Khan assumed the president's role in May 2019.

"We believe that having our own in-house team drives a sense of ownership over the product. We have to eat our own cooking, because what we build, we have to support," Khan says.

Compared with the outsourcing model, the in-house team enables the company to more quickly release higher-quality products and more quickly respond to customers' needs, he says.

"Over the years, The Now Network has seen immense growth, consistently advancing its technology framework to drive faster payments, increased driver retention, an expanded 3PL network, and increased business revenue," Sam Simon, the company's founder, chairman, and CEO, says in a release. "The addition of an in-house development team will only amplify this growth, promoting more opportunities for cross-collaboration and customer feedback, to expand upon and refine existing features."

Members of the in-house development team are working on expansion of The Now Network's last-mile logistics platform for wholesalers, third-party logistics (3PL) carriers, drivers, and users of fuel. Khan says the platform offers "complete visibility and accuracy" throughout the fuel delivery process.

Competition for tech talent in Houston industries like energy and manufacturing is ramping up as the region evolves as "a fast-paced, innovative environment," he says.

"We believe companies like ours offer an opportunity to build a product from the ground up," Khan says, "and in an environment that allows them to express themselves creatively."

In June 2019, staffing firm Robert Half Technology put Houston in fourth place for the anticipated volume of IT hiring in U.S. cities during the second half of the year.

"The technology market in Houston remains strong as more companies are investing in systems upgrades, focusing on security, and taking on digital projects," Robert Vaughn, Robert Half Technology's regional vice president in Houston, said in a release. "The candidate market remains tight, and companies that prolong the interview process or don't make competitive offers tend to have the hardest time staffing open roles."

Today, The Now Network employs 15 people, all but one of whom works in Houston. The company expects to grow its workforce to around 30 by the end of 2020, Khan says. To accommodate the larger headcount, The Now Network is moving this month from WeWork at the Galleria to a 6,000-square-foot office in the Upper Kirby neighborhood.

To help finance its growth, The Now Network will soon launch its first-ever fundraising effort. Khan says the company will seek more than $5 million in investment capital.

Founded in 2015, The Now Network strives to simplify the last mile of the "energy ecosystem," which Khan describes as "slow, opaque, and expensive." Its SaaS platform automates delivery functions in the energy supply chain, doing away with manual labor and tedious paperwork, he says.

Since early 2018, the startup has handled more than 180,000 customer transactions involving over 1.8 billion gallons of fuel.

The Now Network is a portfolio company of Simon Group Holdings, a private equity firm based in Birmingham, Michigan. One of its key areas of focus is the energy sector.

In 2017, The Now Network (previously known as FuelNow Network) entered a strategic partnership with Houston-based Motiva Enterprises LLC, a fuel refiner, distributor, and retailer owned by Saudi Refining Inc. Khan says his company is collaborating with Motiva to roll out The Now Network platform to U.S. fuel wholesalers.

"As of now, Motiva doesn't have a stake in our company," he says.

Motiva owns East Texas' 3,600-acre Port Arthur Refinery, the largest oil refinery in North America, with a daily capacity of more than 600,000 barrels. State-controlled Saudi Aramco — which went public last year in an IPO valued at $2 trillion — owns Saudi Refining.

AI-powered Houston startup helps restaurants boost customer loyalty

order up

It’s no secret that restaurant trends move fast and margins run thin. And with the proliferation of platforms like Uber Eats, DoorDash and Easy Cater, customer loyalty is fleeting.

The solution?

How about an AI-powered restaurant technology platform that helps restaurant brands cut back on third-party platforms in favor of driving direct discovery, conversion and loyalty?

Enter Saivory. Founded in 2025 by Stephen Klein, a software investor, and Fajita Pete’s restaurateur Hugh Guill, the Houston-based startup aims to help eateries better understand and activate guest behavior across digital channels as AI increasingly reshapes how consumers discover and engage with brands.

In less than a year, Saivory has partnered with Shipley Do-Nuts and Fajita Pete’s to bring AI-powered ordering to life.

“With Saivory, we were able to answer the question of, ‘what if the ordering process could be reduced to a single step, where customers simply tell us what they want and AI takes care of the rest?’” Klein tells InnovationMap.

The Houston-based startup made such an immediate impact that it was selected as a semi-finalist during Start-Up Alley at MURTEC, the restaurant industry’s leading technology conference, which took place last month in Las Vegas.

“Houston is a great hub for technology innovation, and we were proud to represent the city at MURTEC this year,” says Klein. “We didn’t win, but we were able to talk about some of the work that we have existing in the market for clients right now and a little bit about what we’re working on in the future.”

In the current restaurant technology ecosystem, the third-party aggregators own the customer attention that brings volume to restaurants, while also taking big commissions and having control over the end relationships with the customer.

That can often make it difficult for restaurants to grow loyalty and repeat business from customers. Saivory aims to level the playing field for restaurants, helping them stay more connected to their customers.

Take Saivory’s recent application with Shipley’s Do-Nuts, for example.

Saivory powered the donut giant’s AI-ordering and launched Shipley's website and mobile app to support its over 300 locations in Texas alone.

Shipley’s new AI-powered assistant helps users create personalized order recommendations based on individual or group preferences. And unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size. It can also be used for large catering orders.

“They're seeing more traffic to the site and they're seeing when customers use our AI-enabled flows,” Klein says. “And they're seeing higher basket sizes, bigger tickets, by about 25 percent.”

Klein says Saivory’s technology helps strengthen first-party digital relationships, reduce friction and cart abandonment, improve average order value, and delivers personalized, efficient experiences.

“It’s a win-win: the customer gets the right order quickly, while the restaurant gets a bigger margin,” he adds.

Additionally, the technology makes it easier for restaurants to share rewards, loyalty and discounts, ultimately growing more direct traffic and making restaurants less reliant on third-party delivery apps.

Next up for Saivory is adding new components to its platform to enhance the relationship between restaurant and customer, as well as technology around making it easier for restaurants to get found on Google.

“A lot of people are still searching for the best donuts near me,” Klein says. “Or what’s the best Mexican food near me? Customers will increasingly move to AI, where they’re going to ask where they should eat dinner and expect it to just order them dinner. They will eventually expect the technology to know how to do that. So that’s what we’re driving at.”

Houston leads U.S. in population growth for 2025, Census says

Boomtown

Imagine that the Houston metro area swallowed a city the size of Pearland in just one year. That’s essentially what happened from 2024 to 2025, with the Houston metro ranking first in the U.S. for population growth based on the number of people.

New estimates from the U.S. Census Bureau show the 10-county Houston metro added 126,720 residents from July 1, 2024, to July 1, 2025. That’s just shy of Pearland’s roughly 133,000-resident tally.

To calculate population, the Census Bureau counts births, deaths, new residents, and moved-away residents.

Region’s population approaches 8 million

On July 1, 2025, the Houston metro’s population hovered slightly above 7.9 million, up 1.6 percent from the same time in 2024. In the very near future, the region’s population should break the eight million mark.

This follows massive growth in the past 20 years. From 2005 to 2025, the region’s population soared by 39 percent. By comparison, the growth rate from 2021 to 2025 sat at nine percent.

A forecast from the Texas Demographics Center indicates that under a middle-of-the-road scenario, the Houston metro’s population will reach nearly 8.5 million in mid-2030 and more than 9.5 million in mid-2040.

Dan Potter, director of Rice University’s Houston Population Research Center, attributes much of the region’s population surge to people moving to the area from outside the U.S. In Harris County, this means a combination of military personnel returning home, people living or working overseas coming back to the U.S., and immigrants relocating to the U.S., he tells CultureMap.

But Harris County fell short from 2024 to 2025 when it comes to people moving here from elsewhere in the U.S., according to Potter. Counties surrounding Harris County benefited from that trend, drawing new residents who preferred to settle in the suburbs.

“The incredible pull and attraction of the Houston area is its economy, its people, and its affordability, and the significant growth that was observed in 2024 and again in 2025 speaks to the magnetism of the region,” Potter says. “That pull to Houston is too strong to be turned off overnight.”

Cooling economy and immigration shifts slow down growth

Whether looking at urban or suburban places, population growth in the Houston area slowed in 2025 and appears to be slowing even more this year, Potter says.

“A cooling economy and changes to immigration policy are a one-two combination that could knock out the region’s population growth,” says Potter, citing the region’s addition of a less-than-expected 14,800 jobs in 2025 as an example.

Weaker population growth may not be felt evenly across the metro area, according to Potter.

A continuing influx of people from Houston to outlying counties such as Brazoria, Fort Bend, Liberty, Montgomery, and Waller could curb growth in Harris County, Potter said. Why? If the number of people arriving from other other countries flattens or even drops, then there could be “doughnut-style population growth for the next few years, where Harris County and Houston see declines while the suburban counties see an increase.”

Harris County represents 40 percent of region’s population lift

Houston-anchored Harris County accounted for almost 40 percent of the region’s population spike from 2024 to 2025. In one year, Harris County grew by 48,695 residents, or 1 percent, pushing its population past five million. That increase put Harris County in first place for numeric growth (rather than percentage growth) among all U.S. counties.

From 2020 to 2025, Harris County’s growth rate was 6.6 percent. It remains the country’s third largest county based on population, behind Southern California’s Los Angeles County and Illinois’ Chicago-anchored Cook County.

Harris County is on track to surpass Cook County in size in the near future. As of July 1, 2025, a nearly 150,000-resident gap separated population-losing Cook County and fast-growing Harris County.

The Texas Demographics Center predicts Harris County’s population will be 5.37 million in mid-2030 and just short of six million in mid-2040.

Suburban counties see significant population gains

Harris County isn’t the only county in the area that experienced a growth spurt from 2024 to 2025:

  • Waller County’s population climbed 5.69 percent, winding up at 69,858. Its growth rate ranked second among U.S. counties.
  • Liberty County’s population rose 4.4 percent to 121,364, putting its growth rate in eighth place among U.S. counties.
  • Montgomery County gained 30,011 residents, with its population landing at 781,194. That placed it at No. 4 among U.S. counties for numeric growth.
  • Fort Bend County picked up 24,163 residents, arriving at a total of 975,191 and positioning it at No. 8 among U.S. counties for numeric growth. Fort Bend County, the region’s second largest county based on population, is projected to break the one million-resident mark by July 2030, according to the Texas Demographics Center.

“Lower mortgage rates from 2009 to 2022 and the rise of remote work have made suburban housing more attractive, especially for families seeking affordability,” Pramod Sambidi, the Houston-Galveston Area Council’s assistant director of data analytics and research, said last year. “Additionally, suburban areas are seeing more multifamily developments than before the pandemic.”

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
