Houston subsea firm Zupt acquired in offshore tech deal

m&a activity

Houston-based Zupt LLC, a provider of advanced metrology, inspection, and engineering services for offshore energy and renewable projects, has been acquired by Columbus, Ohio-based Rosenxt Holding USA for an undisclosed amount.

Rosenxt says the deal, which closed July 21, represents another step in its long-term strategy to build a portfolio of technology and engineering capabilities for the subsea market in the energy sector.

“Our ambition has always been to think decades ahead,” Hermann Rosen, chairman of Switzerland-based Rosenxt Group, the parent company of Rosenxt Holding USA, said in a news release.

“The future of subsea and offshore industries will be shaped by intelligent technologies that fundamentally change how critical infrastructure is explored, installed, inspected and operated,” he added. “Zupt is another important building block in this vision.”

Rosenxt says offshore operators and installation contractors face pressure to execute subsea projects more efficiently amid workforce shortages, weather concerns, tougher safety standards, and rising capital and operating expenses.

“The offshore sector continues to embrace technologies that enhance data quality, reduce operational risk, and improve decision-making across the asset lifecycle,” Houston M&A attorney Amelia Zhang, who led law firm Norton Rose Fulbright’s representation of Zupt, added in the release.

Rosenxt provides services for the subsea market that combine sensing, robotics, AI, analytics and engineering. Zupt complements those services with offerings for operations, such as high-resolution 3D inspection, digital twin generation, and inspection and engineering technologies for subs.

Zupt President Keith Vickery founded the company in 2005.

Vickery says Zupt “has focused on solving some of the subsea industry’s most demanding marine construction and inspection challenges through innovative engineering, operational experience, and close collaboration with our customers.”

Mordor Intelligence estimates the value of the subsea market will climb from $19.75 billion this year to $25.03 billion in 2031. North America represents the largest segment of the global market.

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."
