In the alphabet, Zed is the end of the line. In Boulder, Colorado, Zed Industries just made the case that it’s the beginning of the next frontier in how humans, machines, and code collide.
Founded in 2021 by three GitHub veterans, Nathan Sobo, Antonio Scandurra, and Max Brunsfeld, the company was born out of frustration with the old guard. These were the minds who built Atom and Tree-sitter, who saw the limitations of text editors that couldn’t keep up with modern development, and who decided to start over in Rust. Zed isn’t some patchwork update to the tools we’ve all tolerated for years, it’s a code editor designed for performance, multiplayer collaboration, and now, for working seamlessly alongside AI agents.
That vision just got rocket fuel. Zed Industries has raised a $32 million Series B led by Sequoia Capital with Sonya Huang stepping onto the board. Redpoint Ventures and Root Ventures doubled down, joined by angel investors from Figma, GitHub, CockroachDB, and Superhuman. Stack that on top of the $10 million Series A from March 2023 and the $2.5 million seed in 2021, and the total haul comes to $44.5 million. For a team of just fifteen, that’s efficiency most startups would sell their soul for.
And here’s why: traction. In a little over a year since going open source, Zed has pulled in 64,000 stars on GitHub, drawn contributions from more than 1,100 developers, and attracted over 150,000 monthly active users. Nine percent of all Rust developers now use Zed, up from 1% last year. The State of AI 2025 report ranked it the second most popular AI IDE, while engineering teams at Anthropic, Linear, Ramp, and Shopify are already running it in production. When legends like Mike Bostock, Mitchell Hashimoto, and Solomon Hykes start coding in your editor, you know you’re onto something real.
This round will push Zed further into uncharted territory: operation-based version control with edit-level granularity, character-level permalinks for contextual code conversations, and persistent AI collaboration that doesn’t just autocomplete, it collaborates. Built in Rust, powered by a GPU-accelerated UI, stitched together with CRDTs, and licensed with GPL, AGPL, and Apache where it matters, Zed is turning the code editor into a multiplayer canvas for both humans and machines.
