GitHub is the default place software teams already host and review code, not an AI lab in its own right, so most teams add Copilot rather than switching platforms. Since Microsoft folded it into the CoreAI division, GitHub runs as a roughly 7,700-person unit inside Microsoft rather than an independent company.
GitHub is a code hosting and developer collaboration platform with more than 500 million repositories, the backbone for open-source and enterprise software teams worldwide. Its defining feature is GitHub Copilot, an AI coding assistant built directly into the platform, spanning autocomplete, in-editor chat, and autonomous multi-step coding agents.

About GitHub
GitHub was founded in April 2008 by Tom Preston-Werner, Chris Wanstrath, P.J. Hyett, and Scott Chacon as a web-based Git repository hosting service built to make code collaboration accessible to developers at any skill level. Microsoft acquired the company in October 2018 for $7.5 billion in stock, folding it into its cloud and AI strategy while keeping GitHub's brand and developer-first culture independent. GitHub is headquartered in San Francisco and, as of September 2025, employed roughly 7,700 people worldwide. GitHub's core product is a code repository and collaboration platform supporting 72 programming languages, providing version control, code review, issue tracking, project management, and CI/CD through GitHub Actions. GitHub Enterprise Cloud adds advanced security, compliance, and management controls for organizations. GitHub Models gives developers API access to frontier language models from Anthropic, Meta, Microsoft, and OpenAI, and the platform integrates with hundreds of third-party cloud, project-management, and security tools. GitHub's most significant recent product is GitHub Copilot, an AI coding assistant launched in 2021 that reached 4.7 million paid subscribers by January 2026, a 75% year-over-year increase, with adoption at nearly 140,000 organizations on Copilot Enterprise. Copilot Chat provides an agentic interface capable of multi-step coding sessions, pull request summaries, and autonomous repository research. On June 1, 2026, GitHub shifted Copilot from request-based to usage-based billing calculated by token consumption. GitHub's business model is consumption-based SaaS: GitHub.com is free for public repositories, GitHub Enterprise Cloud is licensed per user for organizations, and Copilot is licensed separately and increasingly via usage tokens. GitHub also runs GitHub Marketplace (referral revenue from partner integrations), GitHub Sponsors (revenue sharing with open-source maintainers), and GitHub Enterprise Server for on-premises deployment. GitHub's total revenue exceeded $2 billion in annual run rate in 2025-2026, with Copilot cited by Microsoft CFO Amy Hood as the majority driver of incremental growth; GitHub paused new individual Copilot sign-ups in February 2026 due to compute infrastructure strain. Thomas Dohmke served as GitHub's CEO from 2021 until his departure in August 2025 to launch a new venture called Entire; Microsoft chose not to name a replacement, instead folding GitHub into its CoreAI division under Jay Parikh, a former Meta engineering executive who reports directly to Satya Nadella. GitHub's global workforce spans engineering (roughly 2,000-2,500), product and design (800-1,000), and operations, sales, and support (1,200-1,500), based across San Francisco, New York, London, Tokyo, and Sydney with significant remote work. GitHub's stated mission, "GitHub Everywhere," aims to make the platform the default choice for developers from individuals to enterprises. GitHub publishes the annual Octoverse report analyzing repository and language trends, contributes to open-source Git tooling and software supply chain security standards, and offers free accounts and open-source plans. On AI safety, GitHub publishes Copilot system cards per release, lets individual users opt out of having their code used for training (business and enterprise accounts are exempt), and has submitted Copilot Business to third-party red-team evaluation by METR and Apollo Research. GitHub's direct competitors include GitLab (open-source, self-hosted focus), Bitbucket (Atlassian's Git platform), Gitea (self-hosted), and code-intelligence player Sourcegraph, alongside AI-first entrants like Cursor and Zed. GitHub's moat rests on network effects, Microsoft distribution through Codespaces, Azure, and Teams integration, and Copilot's access to frontier models; its main weakness is cloud-only pricing that can alienate organizations wanting on-premises or air-gapped deployments. Under the EU AI Act, GitHub carries systemic-risk obligations as a general-purpose model provider, with compliance audits due by August 2026, and operates under Microsoft's Azure AI governance framework rather than a standalone responsible-scaling policy. GitHub's 2026 priorities center on deepening Copilot's reach: expanding Copilot Chat into its mobile app and Windows Terminal, fine-tuning Copilot on private codebases for Enterprise customers, integrating Microsoft's Phi models to reduce third-party LLM dependency, and hardening Copilot against prompt injection. Microsoft has signaled no near-term GitHub IPO, treating it as a core cloud property alongside Azure and Microsoft 365.

Frequently Asked Questions
How was GitHub funded, and how much is it worth?
GitHub raised early venture funding before being acquired outright by Microsoft in October 2018 in a $7.5 billion all-stock deal. Microsoft does not break out GitHub's financials separately, so the company has no independent valuation, stock ticker, or minority owners; it operates as a wholly owned subsidiary. Its scale shows up in usage instead: annual run-rate revenue has passed $2 billion, with GitHub Copilot cited as the main driver of recent growth.
What products does GitHub make in 2026, and what do they cost?
GitHub's core products are GitHub.com (free for public repositories, paid tiers for private team use), GitHub Copilot (Pro at $10 a month, Business at $19 per user monthly, Enterprise at $39 per user monthly), and GitHub Enterprise Cloud at $210 per user per month for organizations needing advanced security and compliance. GitHub Actions handles CI/CD, and GitHub Models gives API access to frontier models like Claude, GPT-4o, and Llama.
How does GitHub handle data privacy and compliance?
GitHub's certification set covers ISO 27001 and ISO 27701 alongside SOC 2 Type II, plus a GDPR-compliant Data Processing Agreement with Standard Contractual Clauses for international transfers. By default, GitHub does not train models on customer code, keeping data only 30 days for abuse monitoring, and enterprise customers can request zero retention. HIPAA-eligible tiers and EU, Australia, U.S., and Japan data residency are available through Azure-backed infrastructure.
Who are GitHub's main competitors?
GitHub's closest rivals are GitLab, which competes on open-source and self-hosted deployment, Atlassian-owned Bitbucket, and code-intelligence tool Sourcegraph, plus AI-first challengers like Cursor. GitHub leads on scale and AI adoption, with 90% of Fortune 100 companies on the platform and 81% developer preference versus 36% for GitLab in 2026 surveys. It loses on cost, since GitLab's comparable tiers run roughly 35% cheaper, and on open-source philosophy, since GitLab's core product is open while GitHub's is proprietary.
How do you start using GitHub's products?
Individual developers can sign up free at github.com and host unlimited public repositories right away. Adding GitHub Copilot for AI-assisted coding is available directly from account settings, starting with the Pro tier for individuals. Organizations evaluating GitHub Enterprise Cloud or Copilot Enterprise typically work with GitHub's sales team to scope security, compliance, and per-seat pricing.
