Through disciplined investment, strategic acquisitions and targeted leadership additions, SeaCube Container Leasing, a global provider of intermodal equipment, is on a mission to enhance its ability to deliver reliable, scalable and sustainable refrigerated equipment solutions and customer value.
“Volatility is now a constant,” Bob Sappio, CEO of SeaCube, said. “Amid shifting trade policy and rising geopolitical risk, the refrigerated cargo market continues to prove durable.”
As part of its growth strategy, SeaCube has strengthened its leadership team with key senior appointments to support its continued transformation:
- Jakob Karstoft, chief commercial officer, leads global commercial strategy with an emphasis on customer-focused solutions and sustainable growth. Based in Europe, he brings broad experience from over 15 years at Maersk Line.
- Ben Thomas, chief financial officer, succeeds long-time SeaCube CFO Dave Doorley, who was instrumental in driving the company’s sustained growth and will retire in June 2026. Thomas’s appointment reflects a well-deserved promotion following his significant contributions as SeaCube’s vice president and treasurer since 2019.
- James Armstrong, senior vice president, emerging business, oversees SeaCube Cold Solutions and Martin Container, leading the combined platform’s strategic growth and operational direction. He is responsible for shaping go-to-market strategy and developing portable cold storage solutions for customers across the U.S. Armstrong’s focus is on building nationally scalable service capabilities while maintaining the relationship-driven, local approach that defines SeaCube’s customer experience.
- Matthew Salmi, vice president of marketing and commercial strategy, guides SeaCube’s brand, marketing and communications as the company advances its solutions-focused approach, connecting customers with innovative cold chain offerings.
A key milestone in SeaCube’s growth is the acquisition of Martin Container, a nearly 50-year-old, family-owned portable cold storage company serving the West Coast. SeaCube has also partnered with The Wonderful Company to establish the Shafter facility as its primary Central Valley depot, supporting storage and maintenance needs across California, Arizona and Nevada.
“Companies that succeed will be those that think beyond the assets, embrace technology and deliver solutions that meet evolving customer needs,” Sappio said. “At SeaCube, providing solutions is central to everything we do. It’s how we adapt, innovate, overcome and grow, and it will continue to be key to our continued success.”
