Tailscale, a company that enables organizations of all sizes to easily create and manage human-scale, trustworthy, private networks, has secured $100 million in Series B funding. The round is led by CRV and Insight Partners with participation from Accel, Heavybit, Uncork Capital, and prominent individual investors. Tailscale plans to use the fresh capital to hire top engineering talent to expand the company’s product-led growth, as well as scale out its go-to-market and strategic partner initiatives.

Founded in 2019, Tailscale helps make private network connectivity fast, effortless, and seamless while allowing security teams to rest easy with end-to-end encryption, no single point of failure, near-instantaneous setup, and zero-config. The company said it experienced 1200% YoY growth and continues to sustain 20% growth quarter over quarter in active monthly users, primarily due to organic word-of-mouth.

Tailscale is based on WireGuard, the open source, opinionated standard for secure connectivity, and is set up and configured in a matter of minutes on average. It integrates with existing identity services including Google Workspace, Microsoft 365, and Okta for seamless authentication and delivers an all-in-one Zero Trust solution for Secure Access Service Edge (SASE), Identity and Access Management (IAM), and Privileged Access Management (PAM) that simply works.

Tailscale integrates with cloud-native tooling that developers depend on such as Syncthing, VScode, and Caddy Server. It also helps remove common remote development hurdles by securely connecting the right people to the right resources.

Tailscale has released remote development integrations with GitPod, Coder, Materialize, GitHub Codespaces, and Indent in the last six months alone.
