Houston software startup Voyager is making waves in its quest to improve efficiency — and stem billions of dollars in losses — in the maritime bulk-shipping business. Now, it's got some fresh capital to help it achieve that mission.

On August 21, Voyager revealed it secured $1.5 million in seed funding from four investors from around the world: Austin-based ATX Venture Partners, Houston- and California-based Blue Bear Capital, New York City-based GreenHawk Capital, and Oman-based Phaze Ventures. Previous investors include Boulder, Colorado-based Techstars and Spring-based Knightsgate Ventures.

With its software-as-a-service offering, Voyager aims to modernize the workflows of operators in the maritime bulk-commodities industry. The company says its technology will become more vital as autonomous shipping and internet- and Internet of Things-enabled cargo vessels grow in popularity.

Voyager's technology enables all communication tied to a shipment to be handled via its web dashboard and app, essentially creating a one-stop shop for people who need to track messages about maritime bulk shipments.

"Shipping bulk commodities like crude oil, gas, and petrochemicals is still a highly manual and complex process, with $360 billion in ocean freight managed globally by email, phone, fax, and text in a high-volume, fast-paced environment," Matthew Costello, co-founder and CEO of Voyager, says in a release. "Data is decentralized and unstructured, and the process is rife with inefficiencies, lost opportunities, costly human errors and, overarchingly, billions in losses."

One shipment alone generates more than 4,000 emails and hundreds of documents, with at least 10 companies collaborating across several time zones, according to Voyager.

Voyager says the $1.5 million in funding will go toward:

  • Expanding its line of SaaS products.
  • Attracting more customers. This includes a foray into the oil and gas sector.
  • Enlarging its engineering, development, marketing, and sales teams. Voyager currently employs seven people at the company's new office in downtown Houston. Plans call for a 10-member workforce by the end of 2019 and a 20-member workforce by the end of 2020.

Costello and Bret Smart, Voyager's chief operating officer, launched the company in 2018. Both are veterans of the maritime industry, where they conducted a study that found roughly 40 percent of workers' time was spent on simple, low-value tasks like manual data entry. With that research in hand, Costello and Smart — who worked together at Stolt-Nielsen, a London-based provider of liquids transportation and storage that has a Houston office — came up with the Voyager software.

Among Voyager's customers are brokerage, terminal, and agency businesses, as well as ship owners and commodity producers. The company says one of its customers has realized more than $4 million in annual bottom-line savings by switching to Voyager, with another customer pegging its annual savings at $1.5 million.

"As industries move away from email to digital-based communication, Voyager will become a critical system of engagement," Costello says.

Down the road — or, in this case, the shipping channel — Voyager plans to supplement its cloud-based offerings with capabilities like machine learning and analytics.

"Opportunities for innovation in maritime abound, as the need for technological advancements exist in one of the world's biggest industries. Voyager is poised to be the leader in maritime operations," says Chris Shonk, managing partner of ATX Venture Partners.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
