About
Tabnine is a Tel Aviv, Israel-based AI code completion and developer productivity platform — backed by $67.4 million in total funding including a $25 million Series B led by Telstra Ventures and Atlassian Ventures in November 2023 — providing 1 million+ developers and 10,000+ enterprise customers (including Accenture and LG Electronics) with AI-powered code suggestions, whole-line completion, function generation, and an enterprise-grade AI coding assistant that offers on-premise deployment, strict data privacy controls, and customization on proprietary codebases — differentiating from GitHub Copilot and Cursor through enterprise security compliance and code privacy guarantees. Recognized as a Gartner Visionary in the 2025 AI Code Assistants Magic Quadrant, Tabnine supports 30+ programming languages and 20+ IDEs.
In talks to raise $2B at $50B valuation in Apr 2026 (Thrive, a16z, Nvidia). $2B+ ARR; revenue projected >$6B by EOY 2026. Used by 50%+ of Fortune 500.
About
Cursor is an AI-first code editor founded in 2022 by a small team of MIT researchers, built as a fork of Visual Studio Code with native large-language-model intelligence woven directly into the editing experience. Its mission is to make software engineers dramatically more productive by embedding AI reasoning into every layer of the IDE — from autocomplete to multi-file edits to natural-language code generation — rather than bolting AI on as an afterthought.\n\nThe platform centers on a VSCode-compatible editor that developers can adopt with zero workflow disruption, layering in features like Tab (predictive multi-line completion), Chat (context-aware in-editor assistant), and Composer (autonomous multi-file refactoring agent). Cursor reads and indexes entire codebases, allowing it to propose changes that span dozens of files coherently. It supports all major languages, integrates with existing extensions, and lets teams configure which underlying model — GPT-4o, Claude, or others — powers suggestions. Fortune 500 engineering teams adopt it alongside individual developers, and it is used by more than half of Fortune 500 companies.\n\nCursor reached $2 billion in annualized recurring revenue by early 2026 and raised at a $29.3 billion valuation, cementing its position as the dominant commercial AI coding tool. The company raised $2.3 billion in total funding and is widely regarded as the category-defining product in agentic IDE software, outpacing GitHub Copilot on developer mindshare metrics in multiple surveys.
