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.

Houston suburb launches innovation grant program to attract startups

innovation incentive

Think you’ve got a burgeoning startup? Consider moving it to southwest Houston. The City of Sugar Land announced the Sugar Land Starts Innovation Fund last week to support companies that move jobs to the area.

“The Sugar Land Starts Innovation Fund is designed to support companies that are ready to grow and make a meaningful, long-term commitment to our community,” Colby Millenbruch, business recruitment manager for the City of Sugar Land, said in a news release. “By focusing on revenue-generating startups and performance-based incentives, we are creating a clear pathway for innovative companies to scale while reenergizing existing office space.”

The performance-based, non-equity dilutive grant program is open to companies that demonstrate at least $250,000 in generated revenue or $500,000 in institutional backing from a bank or venture capital firm. They must commit to hiring or relocating at least three employees in Sugar Land for a minimum of three years and at an average salary of $61,240. Compliance will be verified through Texas Workforce Commission reporting.

The fund builds off the Sugar Land Plug and Play partnership to turn the city into an innovative technology hub.

Collaboration with the Silicon Valley-based startup incubator and accelerator on a physical location in southwest Houston has supported 22 startups and has raised $6.5 million in capital since it officially launched in Sugar Land last March. Companies located at the Sugar Land Plug and Play include Synaps, a browser-based design platform for architects, and Intero Biosystems, which produces miniature human organs for preclinical drug development.

In addition to direct funding and business space, both the new grant and the overall Plug and Play project facilitate meetings with Houston-area businesses like CenterPoint Energy.

This should not only bring new industries to Sugar Land, but also allow existing companies to expand outward as technological investors to create a web of new progress.

“This investment is about more than technology. It’s about creating an environment where innovation can take root, grow, and deliver lasting value for the Sugar Land community,” David Steele, director of Texas at Plug and Play, added in the release. “Sugar Land is setting itself apart by taking a long-term view, investing in founders, partnerships, and technologies that will define the next chapter of growth. We’re proud to partner with the city in building an innovation ecosystem that benefits both entrepreneurs and the broader community.”

Income study shows $100,000 salary goes further in Houston in 2026

Money Talk

A 2026 income study has good news for big earners in Houston: A six-figure salary goes further than it did last year.

A Houston resident's $100,000 salary is worth $84,840 after taxes and adjusted for the local cost of living, according to the new financial analysis from SmartAsset. That's about $1,500 more than Houstonians were bringing home last year.

The 2026 take-home pay is about 8 percent higher than it was in 2024, when the same salary had an adjusted value of $78,089.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities. The figure was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services). Cities were then ranked based on where a six-figure salary is worth the least after applicable taxes and cost of living adjustments.

Houston ranked No. 60 in the overall ranking of U.S. cities where $100,000 is worth the least. If the rankings were flipped and the cities were ranked based on where $100,000 goes the furthest, that places Houston in the No. 10 spot nationwide.

Manhattan, New York remains the No. 1 city where a six-figure salary is worth the least. A Manhattan resident's take-home pay is only worth $29,420 after taxes and adjusted for the cost of living, which is 3.10 percent lower than it was in 2025.

SmartAsset determined Manhattan has a 29.7 percent effective tax rate on six-figure salaries. Meanwhile, the effective tax rate on a $100,000 salary in Texas (based on the eight cities examined in the report) is 21.1 percent. It's worth highlighting that New York implements a statewide graduated-rate income tax from 4-10.90 percent, whereas Texas is one of only eight states that don't tax residents' income.

Oklahoma City, No. 69, is the U.S. city in the report where a $100,000 salary stretches the furthest. A six-figure salary is worth $91,868 in 2026, up from $89,989 last year.

This is the post-tax value of a $100,000 salary in other Texas cities, and their ranking in the report:

  • Plano (No. 27): $72,653
  • Dallas (No. 47): $80,103
  • Austin (No. 53): $82,446
  • Lubbock (No. 59): $84,567
  • San Antonio (No. 62): $86,419
  • El Paso (No. 67): $90,276
  • Corpus Christi (No. 68): $91,110
According to the report, getting some "financial breathing room" by making six-figures really depends on where someone lives and what their lifestyle is. For residents living in the 42 states that levy some amount of income tax, their take-home pay dwindles further."And depending on how taxes are filed, reaching a $100,000 income may push a household from the 22 percent to 24 percent marginal tax bracket," the report's author wrote. "Meanwhile, locations with high costs across housing and everyday essentials may be less forgiving to a $100,000 income."

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.
