A-Rent Test Equipment, LLC (“A-Rent” or the “Company”), a leading provider of electrical test equipment rentals, calibration, and asset management services, today announced a majority growth investment from Bregal Sagemount (“Sagemount”), a leading growth-focused private equity firm. The partnership will support A-Rent’s continued expansion and its commitment to helping customers maintain safe, reliable electrical infrastructure.
Founded in 2019 by Paul Seppanen with backing from Sterling Partners, A-Rent is headquartered in Burr Ridge, Illinois, and provides equipment used to verify the functionality, safety and reliability of critical electrical infrastructure. The Company differentiates itself through its extensive fleet, technical expertise, responsive service, and focus on equipment reliability. A-Rent offers same-day pickup and next-day delivery from four strategically located distribution facilities nationwide, with a fifth scheduled to open in Hillsboro, Oregon, in late 2026.
A-Rent currently serves more than 1,000 active customers, including electrical testing firms, engineering firms, contractors, utilities and equipment manufacturers, across the utility, data center, industrial and manufacturing, oil and gas, and renewable energy markets. Building on its foundation in electrical testing, A-Rent established a growing presence in the mission critical industry by providing liquid cooled load banks and accessories for data center testing and commissioning. “Our customers rely on us to provide calibrated, project-ready equipment when and where they need it,” said Paul Seppanen, Founder and Chief Executive Officer of A-Rent. “Sagemount understands the standards our customers expect and shares our ambition for A-Rent’s next chapter. With its support, we can serve more customers and broaden our capabilities while maintaining the responsiveness and technical expertise that define A-Rent.”
The investment will support the addition of electrical test equipment, development of new distribution locations, expansion of A-Rent’s load bank offering, and continued enhancement of the Company’s commercial and technology infrastructure. Sagemount brings an extensive track record of investing across digital infrastructure and equipment leasing.
“Paul and the team have scaled A-Rent rapidly while maintaining the availability and service levels its customers value,” said Gene Yoon, Founder and Managing Partner at Sagemount. “We look forward to partnering with them to support A-Rent’s expansion across new markets and product categories and build on the strong platform they have created.”
“Growing power demand from data centers, grid modernization and electrification is increasing the need for testing across both new and existing infrastructure,” said Will Breskman, Partner at Sagemount. “A-Rent’s scale and national reach position the Company well to serve that demand.”
Lincoln International acted as the exclusive financial advisor to A-Rent. Goodwin Procter LLP and Kirkland & Ellis LLP served as legal counsel to Sagemount.
