Existing investors Accel, Heavybit, Uncork Capital, and angel investors joined the round, led by CRV and Insight Partners. The Toronto-based firm, founded in 2019, provides a WireGuard-based private network connectivity solution with zero-config and end-to-end encryption that interfaces with Google Workspace, Microsoft 365, Okta, Caddy Server, Syncthing, and VScode. Tailscale plans to utilize the fresh cash to hire more people, accelerate expansion, and invest in go-to-market and strategic partner projects, according to the company. “We’ve been pleased to see unexpectedly exuberant, rapid adoption of Tailscale across the community and among our customers. This aggressive funding round represents a clear signal from the market that investors believe in our vision — the Internet’s original vision — of small, trusted, human-scale networks, interconnected,” Tailscale co-founder and CEO Avery Pennarun said.
