Square Robot, Inc.

Based in Massachusetts, US, and founded in 2016 by co-founders William Ohallora, Eric Levitt, and Jerome Vaganay, Square Robot, Inc. operates as a provider of autonomous inspection services using robotic systems to industries such as refining, chemicals, and power generation. In December 2025, Square Robot, Inc. raised an undisclosed amount of series B funding from new investor Marathon Petroleum Corporation, with participation from other unspecified investors.

As of 2024, the company is led by its CEO, David Lamont. Square Robot specializes in the design and manufacturing of autonomous, submersible inspection robots that conduct internal inspections of aboveground storage tanks (ASTs) while the tanks remain operational. These robots utilize advanced technologies, including Phased Array Ultrasonic Transducers (PAUT), to assess tank bottom integrity, focusing on critical zones prone to corrosion that can lead to catastrophic failures. The main service offering includes API 653 and EEMUA 159 certified inspections, catering primarily to industries such as refining, chemical, mining, aviation, renewables, and power generation.

Square Robot's client base includes operators of aboveground storage tanks across various geographical markets, including North America, Europe, and Asia-Pacific, who benefit from improved efficiency, reduced operational downtime, and compliance with regulatory standards. Square Robot generates revenue through direct service contracts with industrial clients that require advanced inspection services for their aboveground storage tanks. Transactions are structured as project-based service agreements, where clients pay for the comprehensive robotic inspection services provided. The company will use the December 2025 funding to support the further development of its robotic platform.
