Greptile

Greptile is an AI code review agent that automatically reviews every pull request with complete context of the codebase — not just the diff. Founded in 2023 by Daksh Gupta, Soohoon Choi, and Vaishant Kameswaran (Georgia Tech alumni) as part of Y Combinator's Winter 2024 batch, Greptile went through YC and raised a $4M seed from Initialized Capital. A $30M Series A led by Benchmark's Eric Vishria at a $180M valuation was reported in talks in July 2025. The company (legally Tabnam, Inc.) is based in San Francisco with a team of 16.

Greptile's technical approach is distinctive: instead of reviewing a PR as an isolated diff, it builds a complete graph index of the repository — every file, function, class, and dependency relationship — and then deploys a swarm of parallel agents to review changes with full cross-file context. This enables Greptile to catch bugs that human reviewers and traditional linters miss, such as unbalanced CUDA releases (caught in NVIDIA's DALI repo), undefined methods breaking downstream steps (Meta PyTorch), and mid-loop overflows creating orphaned keys (Solana). Reviews post to GitHub or GitLab as inline comments with suggested fixes in approximately 3 minutes.

Key integrations make Greptile a central node in agentic development workflows: a 'Fix with Agent' button on every comment that sends the issue with full file context to Claude Code, Codex, Cursor, Conductor, or Devin; /greploop for fully automated review-fix iteration loops; and a Greptile MCP server. TREX (in Beta) extends Greptile to actually write and execute tests in a sandboxed environment for every PR. Trusted by 22,000+ teams including Brex, NVIDIA, Retool, Substack, Scale AI, PostHog, Mintlify, Zapier, WorkOS, Joby Aviation, Bilt, and Crossmint.

Greptile uses a credit-based pricing model. The Starter plan is free for 1 active developer with unlimited repositories and 50 credits/month (50 standard reviews or ~16 TREX reviews). No credit card required.

The Pro plan is $30/seat/month and includes 50 credits per seat, with additional credits available at $1 each. Credits are consumed as follows: 1 credit = 1 standard PR review, 3 credits = 1 TREX runtime review (sandbox test execution). Pro adds team collaboration, admin controls, and access to all Greptile features.

Enterprise pricing is custom and adds SSO, audit logs, self-hosted deployment in your own AWS environment, BYOK (bring your own LLM providers), priority support, and dedicated SLAs. Greptile also offers free usage for qualified open-source projects and significant discounts for pre-Series A startups. A Greptile API is available at discounted bulk pricing for teams building on top of Greptile's codebase intelligence.
