ZeroTier started with a simple idea: networking shouldn’t be hard. We cut through the chaos of legacy systems with secure, encrypted connections that just work, whether it’s one device or a fleet. Forget complexity. Just connect and go.
ZeroTier enables partners to solve some of today’s most critical connectivity challenges.
We know simplicity is harder than complexity. We believe networking should be both simple and intuitive.
We’ve helped shift the industry toward decentralized networking, proved “impossible” demos could become reality, and endured where most startups fade.
Rooted in curiosity and resilience, we take pride in solving hard problems together and know the most exciting work still lies ahead.
What began as a side project to make networking simpler has grown into a platform used by millions worldwide. This is the story of ZeroTier’s journey.
Frustrated by slow, manual networking inside a U.S. government project, our founder, Adam Ierymenko, began coding a better way. His goal: make it effortless to connect devices directly, supporting privacy and decentralization. Two years of spare-time coding led to an open-source release in 2013. On the day it went live, his newborn daughter helped tap the enter key to publish the first version, a fitting start to something built for the next generation.
ZeroTier evolved quickly: ports to Windows, macOS, iOS, and Android; the first version of Central; and the first paying users. Early demos left people stunned (“that’s impossible”), while enterprise customers began deploying ZeroTier in real-world scenarios from Bitcoin hardware to military backpack radios. The first institutional investor, Anorak, joined in 2019, marking the transition from side project to real company.
Pandemic disruption accelerated usage by 20% in a month and pushed the company fully remote. A second seed round, followed by a Series A, led by Battery and Bonfire, provided fuel for growth. The leadership team expanded with Andrew Gault stepping in as CEO in 2024, freeing Adam to focus on building next-generation products. During this period, Adam also faced and overcame a battle with cancer. The team carried the company forward, a testament to its strength and resilience. Today, ZeroTier connects millions of devices across industries while laying the foundation for post-quantum secure networking.
ZeroTier continues to innovate by:
Developing advanced security and connectivity features to keep pace with evolving customer needs.
Expanding enterprise capabilities without sacrificing simplicity.
Staying true to the mission of autonomy, security, and ease at scale.
ZeroTier’s leadership team is driven by the belief that networking should be simple, secure, and reliable.
We’re always looking for smart, no-nonsense people who are ready to make an impact. Your next move starts here.
