One Year of Building Together

One year ago today capped off the craziest 72 hours of our lives. The story of how Cognition and Windsurf came together has been told many times: a first call after 5 p.m. on a Friday, a flurry of texts and emails, almost no sleep, a signed definitive agreement by Monday morning, an announcement tweet that afternoon.

For us on the Windsurf side, it started as one of the scariest times of our lives. Many members of the Windsurf team had just left for Google, recruiters were reaching out to everyone who remained, and customers were calling to understand what was happening. It was a blur of phone calls and meetings to figure out what came next.

On the Cognition side, we knew we had to act fast. Windsurf had millions of users, a brand loved by developers, and a great team. We prepared to head to Windsurf's offices on Saturday with a printed LOI, ready to sign on the spot.

Then, four of us — Jeff and Graham, Scott and Russell — got in a room, and time seemed to slow down. Everything clicked. Cognition had built one of the best engineering orgs in Silicon Valley and was looking for a GTM org; Windsurf had built one of the best GTM orgs and was looking for engineering. Our products didn't even overlap: one of us had been building a cloud agent, the other an IDE. It almost seemed too perfect. Seventy-two hours and very little sleep later, the deal was done.

When we welcomed the Windsurf team to Cognition, we said, "there's only one boat and we're all in it together." One year later, here's what we've built together.

The world has changed in a year

A year ago, most AI code tools were used for simple tasks like autocomplete or explaining a function. Devin was effective at isolated tasks — script writing, bug fixes — but there was a gap between those capabilities and our vision of the future.

Today, Devin has matured from a junior engineer to operating at a mid-to-senior level: launching, scheduling, and managing other Devins, with each new Devin learning from the history of the agents before it. Not only writing code, but testing its own work with computer use, self-verification, and autofixes.

Three days after the deal closed, we shipped Wave 11. We called it "Just Keep Shipping" and it set the tone for the year.

Here's some of what we built over the last 12 months.

The future arrived

We built our own models: SWE-1.5, served at ~1000 tokens per second, then SWE-1.6, then SWE-1.7, launched just last week — the most capable and efficient model we've trained to date. We like to call ourselves the Switzerland of AI, so we put model evaluation in the open with Arena Mode and a public leaderboard.

We launched Devin Review, Devin CLI, Devin 2.2, and Cognition for Government.

Windsurf 2.0 brought every agent into a single command center. Then, we finally unified into one brand with the launch of Devin Desktop, your home for software engineering. Now Devin is available on every surface with any agent and any model.

We put our money where our mouth is with the AI Productivity Guarantee. We entered new industries and partnered with new teams like automakers and systems integrators.

And we became a global company: Cognition's offices now span San Francisco, New York, London, Singapore, and Tokyo. Our teams are on the ground in even more places, and we'll be opening even more international offices soon.

Just keep shipping

We also built many, many other things. Here are some:

July 2025.Voice Mode. Named Checkpoints. @-mention past conversations. Deeper Browser integration. Planning Mode on by default. Workflows and Rules on JetBrains. Devin's MCP Marketplace.

August 2025. DeepWiki in the IDE. Vibe and Replace. Smarter Cascade. Faster Tab. Dev Containers support. 100+ bug fixes in a single wave.

September 2025. Queued Messages.

October 2025. SWE-grep and SWE-grep-mini. IL6-ready.

November 2025. Windsurf Codemaps.

December 2025. Parallel agents. Git worktree support. Multi-pane Cascade. Cascade Dedicated Terminal. Context Window Indicator. Cascade Hooks. System-level Rules and Workflows for enterprise.

January 2026. Plan Mode. Megaplan. Agent Trace. Arena Mode.

February 2026. Tab v2. Variable Aggression. Autofix for review comments.

March 2026. New token-based plans, including Max. Devin can Manage Devins. Schedule Devins.

April 2026. Adaptive. Per-message token counts. Daily limits removed. Self-serve Devin plans. SWE-check.

May 2026. Android emulator support. Devin gets a Windows PC. Auto-Triage.

June 2026. Security in Devin Review. FrontierCode. Devin Fusion.

July 2026. Devin Security Swarm. Devin Security Vulnerability Remediation Program.

Along the way, our team wrote 20M+ lines of code locally, grew from 44 to 350 people, and grew revenue run rate from $73M to $500M+ since merging the brands.

What's next

As we shared when announcing our latest fundraise, we're now shifting to a world of self-driving software development.

Engineers are becoming super engineers, and people who never coded before are able to leverage themselves in ways they never imagined.
