Thesis
Westlake BioPartners is a life science venture capital firm founded in 2018, headquartered in Westlake Village, California. With approximately $1.3 billion raised across multiple funds, including a $450 million third fund launched in July 2023, the firm focuses on incubating and building early-stage biotechnology companies. Their investment thesis is "people-first," aiming to empower entrepreneurs developing life-saving medicines by identifying deprioritized technologies or molecules and building companies around them. They provide venture funding, company formation, board support, and hands-on operational and scientific assistance. Key sectors include biopharma, life sciences, cell and gene therapy, immuno-oncology, engineered cell therapy, oncology drug discovery, and antibody-drug conjugates, with additional investments in healthcare, biotechnology, and technology. Westlake BioPartners targets early-stage investments, leading or co-leading seed and Series A rounds, and reserves capital for follow-on investments through clinical proof-of-concept. Their geographic scope is primarily the United States, with a strategic advantage in the Greater Los Angeles area. They operate exclusively as direct investors, taking equity positions.
