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 robotics company founder plans to take his startup global

houston innovators podcast episode 45

What do space and the ocean have in common? Both have a lot left to explore — while also having environments that aren't so easy for human exploration. A former robotics expert at NASA, Nicolaus Radford founded his cloud robotics company six years ago to create a fleet of robots that can help better complete the tasks that offshore industries need.

Radford remembers his time at NASA and how the organization was looking for opportunities to incorporate more public-private partnerships. Through some meetings and tours, Radford began to see that there was an emerging interest in underwater robotics.

"It became evident that not only was there a huge desire and requirement for what people wanted to do under water, but Houston was likely an epicenter for it," Radford says on the Houston Innovators Podcast.

With this in mind — and an entrepreneurial itch — Radford started Houston Mechatronics Inc. in 2014. He's grown the company through a few venture capital raises and across the energy biz and into new industries. Now, he's looking to take the company global with plans for opening new offices in the United Kingdom and in the Asia Pacific region.

"We're absolutely going to be a global company," Radford says, explaining that new clients in these areas are what's calling for the new offices. "The next 12 months of this company are going to be extremely vibrant and dynamic."

Radford also discusses how the pandemic has affected his business and his challenges raising a round in the episode of the podcast. You can listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes

Houston Innovation Awards honor Don Kendall Jr. with posthumous​ Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida
