Greptile is an AI code review agent that reviews pull requests with full context of your codebase, using a "swarm" of agents to catch bugs, security risks, and multi-file logical issues that a single-pass reviewer would miss, built by Greptile, Inc.
Who builds it
Greptile was co-founded in 2023 by Daksh Gupta, Soohoon Choi, and Vaishant Kameswaran, Georgia Tech alumni, and went through Y Combinator's Winter 2024 batch. The company raised a $4 million seed round led by Initialized Capital after YC, then a $25 million Series A led by Benchmark in September 2025, bringing total funding to roughly $30 million at a reported valuation near $180 million.
Core features
- Full-codebase indexing: builds a graph of a repository's files, functions, and dependencies so review comments account for how a change ripples through the rest of the code, not just the diff.
- Parallel agent review: multiple agents assess a pull request's changes and their broader impact simultaneously.
- Continuous learning: the system adapts to a team's coding standards based on how engineers respond to its comments over time.
- Custom rules: teams can enforce their own conventions written in plain English rather than a rules DSL.
- TREX runtime validation (public beta): writes and runs tests for a PR inside a sandbox rather than only doing static analysis.
- IDE and agent integration: one-click fixes can be sent to Claude Code, Cursor, Codex, or Devin, and Greptile connects to other AI agents via its own MCP server.
Pricing
- Starter (Free): unlimited repositories, 50 monthly credits, 1 active developer seat; a standard review costs 1 credit and a TREX review costs 3 credits; includes a 14-day free trial.
- Pro: $30/seat/month, 50 credits per seat per month included, additional credits at $1 each; unlimited users and repositories, custom rules, and unlimited external app connections; also includes a 14-day free trial.

- Open-source projects under MIT or Apache licenses qualify for free access, and pre-Series A startups under $2M revenue get a 50% discount.
Who it's for
Engineering teams on GitHub or GitLab who want an automated first-pass reviewer with real codebase context rather than a generic linter — Greptile cites more than 9,000 teams using the product, including Brex, NVIDIA, PostHog, Retool, and Substack. The free Starter tier suits individual developers and small projects, Pro fits teams that want unlimited reviewers and repos without an enterprise contract, and Enterprise targets larger organizations that need self-hosting and SOC 2-aligned compliance controls.
