View company profile

The PetLab Co. is a pet wellness brand founded in 2018 by Chris Masanto and Damian Grabarczyk. The company is dedicated to enhancing pet health and quality of life by providing high-quality, science-backed supplements and educating pet owners on building healthy habits for their animals. Initially focusing on canine health, PetLab Co. offers a range of products addressing common concerns such as immune support, joint care, gut health, and dental hygiene. Their mission is driven by the belief that pets are family and deserve the best possible care to live long, healthy, and happy lives. This philosophy originated from co-founder Chris Masanto's experience with his own dog, Krystal, which inspired him to explore ways to improve and extend the lives of pets through better nutrition and proactive wellness.

Since its launch, PetLab Co. has experienced rapid growth, establishing itself as a significant player in the direct-to-consumer pet supplement market. The company emphasizes research-backed ingredients and transparency in its product development, collaborating with PhD nutritionists, product experts, clinical scientists, and specialized veterinarians. This commitment to scientific evidence and innovation is evident in products like their ProBright® Advanced dental powder. PetLab Co. has built a strong global community of pet owners, leveraging an engaging online and social media presence to connect with customers and provide educational content. The company's success attracted a majority stake acquisition by BC Partners in early 2025, a move intended to support further growth, innovation, and expansion of its product portfolio and market reach. Headquartered in London, PetLab Co. also has a significant presence in North America and serves a global customer base, continually striving to be a trusted partner in pet health.
