Tailscale

Mesh VPN building private networks between devices based on identity, replacing traditional VPN concentrators.

Tailscale creates encrypted point-to-point WireGuard connections between a user's devices and servers, with access defined by identity rather than network location. Setup takes minutes and requires no central concentrator, which has driven adoption from homelabs to enterprises, including connectivity for AI and GPU workloads. Founded in 2019, it raised a Series C in 2025.
