About InterWest Partners

InterWest Partners is a long-running Menlo Park-based venture firm with roughly four decades of history investing in healthcare and technology, with a healthcare practice focused on biotech, medical devices, and selectively healthcare IT. The fund has had a quieter recent profile compared to peers but maintains an active healthcare investment mandate with checks in the Series A and B range, generally $5M to $15M, and the ability to lead. Healthcare exposure is meaningful and historically concentrated in therapeutics and devices rather than pure digital health software. AI focus is welcome in drug discovery, medical imaging, and computational biology where the technology meaningfully advances a clinical product. Founders best suited are Series A and B CEOs in therapeutics, medical devices, or AI-driven life sciences with strong scientific credentials and a clear regulatory and reimbursement path. Founders who do not fit include digital health services-only businesses, consumer wellness, and pre-product teams without strong scientific founders. Geographic preference is US with a Bay Area bias but no hard regional constraint. The entry path is warm introduction through a portfolio CEO, a Bay Area life sciences operator, or a co-investor at funds like Versant or Frazier. LinkedIn outreach to a partner with a focused scientific summary is a reasonable secondary option. Expect deep scientific diligence, regulatory questions, and a long-term board partner who will engage on clinical strategy. Founders should confirm fund pacing and active partner availability given the firm’s lower recent profile.
