With new ownership, this strategic investment will accelerate PainTEQ’s expansion by funding prospective clinical studies, advancing development of next-generation products, and expanding the company’s U.S. commercial presence.

PainTEQ’s flagship product, LinQ®, is a proprietary, allograft-based, drill-less SI joint implant delivered via a minimally invasive posterior approach. To date, LinQ® has been used in over 14,000 procedures and is supported by multiple peer-reviewed clinical studies, including the SECURE study, a prospective clinical trial demonstrating improvements in pain and function alongside a strong safety profile.

Under the leadership of CEO Shanth Thiyagalingam, PainTEQ has demonstrated strong operational discipline and commercial leadership. Thiyagalingam brings more than two decades of interventional experience, including senior commercial leadership roles at Abbott, Nevro, and Stryker.

“Partnering with experienced institutional healthcare investors at Signet and Windham marks an exciting chapter for PainTEQ,” said Thiyagalingam. “With a strengthened balance sheet and new committed ownership group, we are well positioned to deliver innovative solutions for patients suffering from SI joint dysfunction and to continue building a category-leading interventional platform. We are grateful to the founding team and prior owners for laying the groundwork that enables this next phase of company growth.”

Dr. Dawood Sayed, Professor and Division Chief of Pain Medicine at the University of Kansas Medical Center and Vice Chair and Co-Founder of the American Society of Pain and Neuroscience (ASPN), commented: “This investment validates SI joint fusion as a critical treatment pathway. It will accelerate innovation and advance research, expanding treatment options in interventional spine care and making this procedure a long-term standard of care.”

About LinQ: The LinQ SI Joint Stabilization System provides patients with a minimally invasive option to combat pain due to sacroiliac disease. After a thorough diagnostic process, physicians may help alleviate – and in many cases eliminate – chronic pain by placing a single LinQ allograft into the SI joint. With its large graft window, the LinQ implant is designed to create an ideal environment for long-term fusion.
