About
Codeium was founded to democratize AI-powered coding assistance by making high-quality code generation and understanding available to every developer, not just those at well-resourced enterprises. The company built its own proprietary AI models trained specifically on code, allowing it to offer a fast, accurate coding assistant without depending on third-party model providers. Codeium's core technology supports over 70 programming languages and integrates natively into more than 40 IDEs, covering the full range of developer workflows from autocomplete to multi-file edits.\n\nCodeium's platform offers both a free tier for individual developers and an enterprise product — Windsurf for Teams — that provides shared context, admin controls, codebase-aware suggestions, and compliance features for engineering organizations. The assistant performs inline autocomplete, chat-based code Q&A, and autonomous multi-step code generation, enabling developers to move faster without sacrificing code quality. Enterprise customers benefit from air-gapped deployment options and fine-tuning on proprietary codebases, making Codeium viable in regulated and security-sensitive environments.\n\nCodeium reached $40 million in ARR with over 700,000 developers and 1,000-plus enterprise customers, processing more than 100 billion tokens daily at the time of its acquisition by Cognition in July 2025 for $2.85 billion. Total funding prior to the acquisition was $243 million. The acquisition by Cognition, the AI software engineering company behind the Devin AI agent, positions Codeium's infrastructure and customer base as a foundation for next-generation autonomous software development.
