Gryphon Investors, a middle-market private equity firm based in San Francisco, has purchased Vetnique Labs.

Headquartered in Naperville, Ill., Vetnique develops a range of pet products including supplements and topical products for digestive health, allergy and dermatological support, ear care, active lifestyle and calming support. In partnership with founder and CEO James Bascharon, who will remain in his current role and maintain a significant equity stake in the business, Gryphon will invest in expanding the company’s product and geographic reach while supporting its mission of developing and delivering products for pets.

“As we continue to see increased use of supplements with companion animals, we believe that Vetnique will stand out as offering differentiated solutions that provide real and lasting benefits for pets,” says Bascharon.

William Blair & Co. LLC served as the financial advisor to Gryphon. Raymond James served as financial advisor to Vetnique. Kirkland & Ellis LLP acted as legal advisor to Gryphon.
