Canadian networking startup Tailscale has raised $160 million in Series C funding, pushing its total capital raised to $275 million. The round, announced Tuesday, underscores growing enterprise demand for secure, scalable connectivity in a remote-first, cloud-powered world.
The latest round was led by Amit Kumar from Accel, with support from CRV, Heavybit, Insight Partners, Uncork Capital, and high-profile angel investors like George Kurtz, CEO of Crowdstrike, and Anthony Casalena, CEO of Squarespace.
Tailscale to Accelerate Global Growth and Innovation
With fresh capital in hand, Tailscale plans to double down on product development, expand globally, and strengthen its engineering, sales, and product teams. The company aims to push the boundaries of what secure connectivity looks like for modern organizations.
Tailscale’s platform is built to help DevOps, IT, and security teams securely connect applications, devices, and services — no matter where they’re located. The company’s zero-trust networking solution is designed to be both seamless and powerful, offering tools like just-in-time access, endpoint detection and response (EDR) integrations, and robust identity-based security.
Powering Security in AI, Finance, Healthcare, and More
Already trusted by organizations across healthcare, finance, manufacturing, government, and IoT, Tailscale’s technology has become a go-to solution for secure remote access and private networking. Its growing role in the AI ecosystem is also gaining attention.
AI companies such as Cohere, Groq, Perplexity, Mistral, and Hugging Face rely on Tailscale to securely connect distributed workloads. In these data-intensive environments, Tailscale enables seamless, encrypted communication across cloud instances, edge devices, and internal tools — a critical advantage for developers building next-generation AI systems.
Backed by Top Investors and Tech Leaders
The strong investor backing signals confidence in Tailscale’s vision and market momentum. Accel’s Amit Kumar highlighted the startup’s unique approach to networking and its potential to become a foundational layer for secure internet infrastructure.
With increasing threats to network security and the growing complexity of hybrid and remote environments, Tailscale is positioning itself as a vital tool in the modern enterprise security stack.
