• Emergo by UL: Global medical device regulatory and quality consulting arm of UL, with dedicated Human Factors Engineering services. Larger incumbent offering HFE as part of a broader portfolio (regulatory, quality, clinical) — overlaps with Thay Medical on FDA/EU MDR usability validation but serves many other adjacent needs.
