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."

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 researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”
