San Francisco, CA — August 3, 2026 — Lamart Corporation (Lamart or the Company), a family-owned manufacturer of engineered, coated and laminated flexible materials serving technically demanding applications, announced today that it has entered into a new ownership partnership with Industrial Growth Partners (IGP), a San Francisco-based private equity firm providing transformative capital for the industrial market. The Hirsh family will remain significant minority shareholders in Lamart and the Company’s day-to-day leadership and operations will remain unchanged.
With operations in Clifton, NJ, San Diego, CA, and Ensenada, Mexico, Lamart is a critical manufacturer of high-performance tapes, films, insulating materials and fabrics to the aerospace and defense, space, automotive, construction, energy, medical, industrial, and optical end markets.
“Our family has spent over seven decades building Lamart as a problem solver for our customers,” said Jonathan Hirsh, Chief Executive Officer of Lamart. “Partnering with IGP allows our team and our family to invest in the next phase of Lamart’s growth, while preserving the culture, craftsmanship and customer focus that have always defined Lamart.”
Craig Hirsh, President and Chief Revenue Officer of Lamart, said the timing reflects years of internal groundwork and planning. “We have kept a long list of capital investments on the whiteboard for some time, driven by customer demand and market opportunities,” he said. “The investment by IGP enables Lamart to execute on that plan with people who get how this industry works. We have already hit the ground running with upgrading one of our existing coaters.”
“Lamart has built a reputation for solving complex materials challenges in highly engineered applications, and the Company’s profile and strategy fits with IGP’s long history of transforming advanced materials companies,” said Roy Seroussi, Partner at IGP. “We are excited to partner with the Hirsh family and the broader Lamart team to support the Company’s next phase of growth.”
Brian Orkin, also a Partner at IGP, pointed to the next phase of growth. “Our goal is to accelerate Lamart’s growth with coating and converting capacity expansion, broadening the portfolio of technologies while pursuing strategic add-on acquisitions to expand the Company’s reach into adjacent materials, end markets and geographies.”
