AI coding assistants companies: 4 verified, updated November 13, 2026
Presspool has verified 4 AI coding assistants companies. Latest rounds: the 4 announced in dollars total $3.35 billion.
A subset of Presspool's AI coding map: companies whose fit on that map places them in AI coding assistants. Companies whose main product is AI that writes, edits, reviews or tests code: AI coding assistants and editors, autonomous coding agents, AI app builders that generate working software, and AI code review and testing. Each company is already on the parent map, where it was taken from the company's own website and confirmed by an independent source, both linked on the entry. No company pays to be listed.
This map does not have its own weekly question set or answer sample. The questions and answer counts for these companies are on the AI coding map.
| Company | What it does | Latest announced financing |
|---|---|---|
| Cursor | Cursor is an AI coding agent and editor whose agents build, test and demo features on their own, and it runs in the terminal, Slack and GitHub pull-request reviews. | $2.3B, Series D (November 13, 2025) |
| Poolside | Poolside builds open-weight agentic coding models, including the Laguna models. | $500 million, Series B (October 2, 2024) |
| Magic | Magic builds frontier code models to automate software engineering and research. | $320M, round type not disclosed (August 29, 2024) |
| Augment Code | Augment Code's Cosmos platform runs AI agent loops that move software work from spec to verification, with engineers controlling the quality gates. | $227M, Series B (April 24, 2024) |
What counts as AI coding assistants
This page lists companies already on the AI coding map. A company is listed here when the fit recorded on that map names AI coding assistants before any other layer. It is not a separate check. Out of scope: companies on the AI coding map whose fit names a different layer first, and anything the AI coding map excludes. General model labs, coding features inside big platforms such as GitHub Copilot or Amazon Q, and developer tools where AI is a feature rather than the product. Definitions are versioned; this is version 1. Corrections need a public source: see Contact.
Changes
- November 13, 2026: Opened as a subset of the AI coding map. Members are companies already on that map whose fit names this layer first. No separate company check was made for this page.
