Houston logistics company works toward software solutions to energy transition challenges

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."

And, predictably, some of those waves are caused by new momentum within the energy transition.

"The energy transition has thrown up a lot of questions for everyone in the maritime industry," Costello says. "The regulations create a lot of questions around cost primarily. ... And that has created a huge number of opportunities for technology."

Fuel as a primary cost for the maritime industry. These cargo ships are traversing the world 24/7 and burning fuel at all times. Costello says there's an increased focus on the fuel process — "all with a goal of essentially reducing carbon intensity usage."

One of the ways to move the needle on reducing the carbon footprint of these ships is optimizing the time spent in port, and specifically the delays associated. Demurrage are charges associated with delays in loading and unloading cargo within maritime shipping, and 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."

The Carbon to Value Initiative (C2V Initiative)—a collaboration between Greentown Labs, NYU Tandon School of Engineering's Urban Future Lab and Fraunhofer USA—has announced 10 startup participants to join the fifth cohort of its carbontech accelerator.

The six-month accelerator aims to help cleantech startups advance their commercialization efforts through access to the C2V Initiative’s Carbontech Leadership Council (CLC). The invitation-only council consists of corporate and nonprofit leaders from organizations like Shell, TotalEnergies, XPRIZE, L’Oréal and others who “foster commercialization opportunities and identify avenues for technology validation, testing, and demonstration,” according to a release from Greentown

“The No. 1 reason startups engage with Greentown is to find customers, grow their businesses, and accelerate impact—and the Carbon to Value Initiative delivers exactly that,” Georgina Campbell Flatter, CEO of Greentown, said in a news release. “It’s a powerful example of how meaningful engagement between entrepreneurs and industry turns innovation into commercial traction.”

The C2V Initiative received more than 100 applications from 33 countries, representing a variety of carbontech innovations. The 10 startups chosen for the 2025 fifth cohort include:

  • Cambridge, Massachusetts-based Sora Fuel, which integrates direct-air capture with direct conversion of the captured carbon into syngas for production of sustainable aviation fuel
  • Brooklyn-based Arbon, which develops a humidity-swing carbon-capture solution by capturing CO₂ from the air or point-source without heat or pressure
  • New York-based Cella Mineral Storage, which works to develop subsurface mineralization technology with integrated software, enabling new ways to sequester CO2 underground
  • Germany-based ICODOS, which helps transform emissions into value through a point-source carbon capture and methanol synthesis process in a single, modularized system
  • Vancouver-based Lite-1, which uses advanced biomanufacturing processes to produce circular colourants for use in textiles, cosmetics and food
  • London-based Mission Zero Technologies, which has developed and deployed an electrified, direct-air carbon capture solution that employs both liquid-adsorption and electrochemical technologies
  • Kenya-based Octavia Carbon, which develops a solid-adsorption-based, direct-air carbon capture solution that utilizes geothermal heat
  • California-based Rushnu, which combines point-source carbon capture with chemical production, turning salt and CO2 into chlorine-based chemicals and minerals
  • Brooklyn-based Turnover Labs, which develops modular electrolyzers that transform raw, industrial CO2 emissions into chemical building blocks, without capture or purification
  • Ontario-based Universal Matter, which develops a Flash Joule Heating process that converts carbon waste such as end-of-life plastics, tires or industrial waste into graphene

The C2V Initiative is based on Greentown Go, Greentown’s open-innovation program. The C2V Initiative has supported 35 startups that have raised over $600 million in follow-on funding.
