Devin

Devin is an AI software engineering agent built by Cognition AI, a company founded in 2023 and headquartered in San Francisco, California. The product is designed to operate as an autonomous coding agent that can plan, write, test, and debug software with minimal human intervention, working within a sandboxed cloud environment.

The core product, marketed under the name Devin, provides parallel cloud-based agents intended for engineering teams. It can handle tasks such as end-to-end feature development, bug fixing, codebase navigation, and integration with existing developer tooling. Cognition positioned Devin as a tool for augmenting software engineering capacity rather than replacing individual developers, targeting teams that want to scale output without proportional headcount growth.

Cognition AI raised a $21 million seed round in early 2024 led by Founders Fund, with participation from other investors including Patrick and John Collison, Elad Gil, and others. The company was co-founded by Scott Wu, who serves as CEO, along with Steven Hao and Walden Yan. The funding announcement coincided with a widely circulated demonstration of Devin's capabilities, which generated significant attention in the software engineering and AI communities.
