4FOX Ventures is a Swiss venture capital firm based in Geneva that invests in early-stage healthcare and technology companies. The firm typically backs companies from pre-seed to Series A, with particular interest in medtech, diagnostics, and deep-tech innovation emerging from strong scientific and engineering ecosystems.

The firm has shown selective but meaningful activity in neurotechnology through investments such as Artiria Medical, which develops neurointerventional guidewires, and Positrigo, which focuses on brain imaging for dementia diagnostics. These positions suggest a practical interest in clinically relevant neurotech rather than a broad sector-wide mandate.

4FOX Ventures focuses primarily on Switzerland, with additional exposure to Asian markets. Its relevance lies in linking Swiss science-driven startups with early capital and broader international market access.
