Greptile

Greptile is a San Francisco-based developer tools company that makes an AI code review agent. The product connects to GitHub or GitLab, builds a graph index of an entire repository — files, functions, classes and dependencies — and then runs a swarm of parallel agents over each pull request to assess the impact of changes beyond the diff. Findings are posted as PR comments, typically in about three minutes, with suggested fixes. Unlike file-by-file linters, the system is designed to catch multi-file logical bugs, security risks and style violations by reasoning across the whole system.

The agent personalizes over time: it reads other engineers' PR comments to learn a team's coding standards, incorporates thumbs-up/thumbs-down reactions and replies to suppress irrelevant suggestions, and auto-detects existing convention files such as CLAUDE.md and .cursor/rules. Teams can also write custom rules in plain English. Greptile positions itself as a "central validation layer" that sits between coding agents and production: review comments can be handed off in one click to Claude Code, Cursor, Codex, Conductor or Devin, a Greptile MCP server exposes comment context and learned rules to any AI agent, and a /greploop command lets a coding agent iterate with Greptile until issues are resolved. A newer agent, TREX, writes and runs tests for each PR in a sandbox to surface missed edge cases. Additional integrations include Jira and Notion, so a review can check a PR against the requirements of its linked ticket.

Greptile is offered as a cloud service (SOC 2 Type II) or self-hosted via Docker Compose or Kubernetes/Helm, including air-gapped environments and customer-supplied LLM providers, with SSO/SAML and audit logs for enterprise buyers. Twelve languages are listed as fully supported (Python, JavaScript, TypeScript, Go, Elixir, Java, C, C++, C#, Swift, PHP, Rust), with other languages supported at lower quality. The company also maintains public repositories including on-prem Helm charts (akupara), a CLI, a VS Code extension, a Codex plugin and agent skills.

Founding story

The three founders — Daksh Gupta, Soohoon Choi and Vaishant Kameswaran — met through Georgia Tech, where Gupta and Choi graduated in 2023 and Kameswaran studied computer science. They entered Georgia Tech's CREATE-X Startup Launch program with a different product, an AI shopping assistant called Tabnam, and pivoted after customer discovery showed their technology was better suited to software development. Gupta has credited CREATE-X with introducing him to co-founder Choi. Press coverage reports the company began in 2023 during a hackathon in San Francisco's South of Market district.

Business model

B2B SaaS sold on a per-seat subscription with credit-based usage. A free Starter tier covers one active developer with unlimited repositories and 50 credits per month; the Pro tier is $30 per seat per month including 50 credits per seat, with additional credits at $1 each. One credit equals one standard review and three credits equal one TREX review. Enterprise deployments add self-hosting, SSO, audit logs and dedicated support, and the review engine is also available via API with discounted bulk pricing.

Recurring per-seat subscription revenue plus consumption-based credit purchases, with API licensing at bulk rates and enterprise/self-hosted contracts.

Traction

The company's site states that more than 22,000 teams use Greptile; a January 2026 Georgia Tech article cites more than 2,000 customers. Greptile reported reviewing over 500 million lines of code in September 2025 and preventing more than 180,000 bugs that month, and its documentation claims 100,000+ bugs caught in production per month, an average review time of about three minutes and 9x faster time to merge. At its Y Combinator launch the company cited 250+ companies using the product. Y Combinator lists a team size of 35; a December 2024 press report described six employees at that time.

Latest developments

In September 2025 Greptile announced a $25 million Series A led by Benchmark Capital, with continued participation from Cory Levy, Y Combinator and Initialized Capital, and released Greptile v3 — a rewrite of the agent architecture with learning from human PR comments, a Greptile MCP server, Jira and Notion integrations, auto-detection of CLAUDE.md and .cursorrules files, and copyable prompts for coding agents. A January 2026 Georgia Tech article reported total capital raised of $30 million and a $180 million valuation, with more than 2,000 customers. The company is also offering early access to TREX, an agent that autonomously writes and runs tests for every pull request.
