Devin (Cognition)
Cognition unveiled Devin in March 2024 as 'the first AI software engineer', capable of taking a Linear ticket and shipping a pull request end-to-end. Independent reviewers (notably Carl Brown's analysis) showed the launch demo was carefully edited and that real-world success rates were modest. Cognition kept iterating and acquired Windsurf in July 2025 to give Devin a real IDE surface. The company's valuation reached $4B+ in 2025 funding rounds.

ðŠĶ Other dead agents tools
Rabbit R1
ð Possibly DeadRabbit launched the R1 in January 2024 with a Teenage Engineering design and a 'Large Action Model' that promised to operate apps for you. Within weeks, reverse engineers showed the device ran a standard Android launcher and that the LAM was largely scripted Playwright automations. Most launch-day integrations (Uber, DoorDash, Spotify) broke or were quietly removed. The company has shipped firmware updates through 2025 but customer count, revenue, and the LAM roadmap have gone quiet.
Olive AI
ðīShutdown / DeadOlive was a healthcare RPA-and-AI company that hit a $4B valuation in 2021 after raising over $900M from General Catalyst, Tiger Global, and Vista. Customer hospitals reported the bots underdelivered and were difficult to maintain. After multiple layoff rounds in 2022 and 2023, Olive sold its two remaining business units to Waystar and Humata Health in October 2023 and shut down. The brand is gone; the website now serves a single sunset notice.
â Frequently Asked Questions
Does Devin actually work?
On well-scoped tasks with good test coverage, yes. On open-ended product work, results vary and most teams still review every PR.
How much does Devin cost?
Pricing is per 'Devin unit' of compute, typically starting around $20/mo plus usage. Enterprise plans negotiate.
How does Windsurf fit in?
Cognition acquired Windsurf in July 2025 to give Devin a first-party IDE where it can pair with humans rather than only running headless.
Is Devin a Cursor competitor?
Partially. Cursor is an AI-augmented IDE for humans. Devin is an autonomous agent. The line blurs as both add the other's features.
