Today that looks like AI that reviews pull requests in GitHub, catching bugs and enforcing standards. Greptile reviews 5B lines of code every month for 22,000+ customers. Problems we’re excited about - Coding standards can be idiosyncratic and are often poorly documented; can we build agents that learn them through osmosis like a new hire might? - Can we identify for each customer what types of PR feedback they do and don’t care about in order to increase signal-to-noise ratio? - Some bugs are best caught by running the code. Can we autonomously deploy feature branches and use agents to try to break the application? - How do we secure a product that processes highly sensitive code across cloud, self-hosted, and air-gapped environments? Trajectory - 22,000+ customers - 5B lines of code reviewed every month - Scaled from $0 to eight figures in ARR - Raised $30M from Benchmark, Y Combinator, Paul Graham, and Initialized ## Team - We have assembled a small, talent dense team who have scaled critical functions at companies like Stripe, Google, Figma, etc. ## Responsibilities - Own Greptile’s security posture across the product, infrastructure, and internal systems - Consult on risky code changes and critical architecture decisions - Fix pentest findings and patch reported vulnerabilities - Manage our bug bounty program and coordinate vulnerability response - Design, implement, test, and deploy secure product and infrastructure improvements - Work directly with engineers to make security part of how we build, rather than a final review step ## Qualifications - B.S. Computer Science or equivalent degree, undergraduate or higher - 3+ years of software engineering, DevOps, or security engineering experience - Experience with JavaScript/TypeScript - Deep knowledge of application, infrastructure, and cloud security - Experience working on security-critical products and complex architectures - Strong judgment when evaluating vulnerabilities, technical tradeoffs, and risk You will like this role if - You want to work on a product that thousands of developers rely on - You want real ownership over the security of a fast-growing technical product - The chaos of high growth and things breaking is exciting to you - You like being in an office every day around other smart people who are excited about what they’re building - You love solving very hard problems. - You specifically prefer working in-person over working remote ## About Greptile ## Company Overview - **One-liner**: Greptile provides an AI-powered code review agent that analyzes pull requests with full codebase context to catch bugs, enforce standards, and autonomously test changes. - **Entity Type**: Private (Y Combinator W24; raised $4M seed + Series A – amount undisclosed – as of Sep 2025) - **Headquarters**: San Francisco, California, USA - **Founded**: 2023 - **Founders**: Daksh Gupta, Soohoon Choi, Vaishant Kameswaran ## Core Business - **Primary industry**: AI-powered developer tools / code quality & validation. - **Target customers**: B2B; engineering teams at startups to enterprises (defense, healthcare, financial services). - **Mission or purpose**: “Build agents that autonomously validate, test, and QA code changes before they are merged” – helping teams merge faster and catch more bugs as software becomes more critical. ## Products & Services - **Greptile Core (AI Code Review)**: A SaaS platform that indexes a codebase into a graph of files, functions, and dependencies, then uses a swarm of AI agents to review every pull request. Integrates with GitHub, GitLab, and coding agents (Claude Code, Cursor, Codex, Devin). Pricing: $30/seat/month (50 credits included, $1/additional credit). - **TREX (Autonomous Test Agent)**: An agent that writes and runs tests for every PR in a sandboxed environment to catch bugs and missed edge cases. - **Greptile API**: Programmatic access for custom integrations, with discounted bulk pricing. - **MCP / Claude Code Plugin**: Connects Greptile to AI agents for sharing comment context and auto-resolving issues. - **Self-Hosted Deployment**: Available in an air-gapped AWS environment, with support for custom LLM providers. SOC 2 compliant, SSO, audit logs, dedicated support. ## Market Standing - **Valuation / Market Cap**: Not disclosed. - **Key Metric**: Total funding – $4M seed (June 2024) + Series A (amount undisclosed, announced Sep 2025). Annual revenue not publicly available. - **Notable Investors / Partners**: Y Combinator (Winter 2024), Brad Flora (primary partner). Customers include Stripe, Amazon, PostHog, Raycast, Vouch, Podium, and YC’s internal software team. - **Growth Signals**: Over 9,000+ teams using Greptile; team grew from 20 (early 2025) to 35 (latest YC profile); attracted enterprise customers in defense, healthcare, and financial services; introduced self-hosted, air-gapped deployment for compliance-heavy industries. ## Competitive Advantages - **Full codebase context**: Builds a graph index of files, functions, and dependencies (not just diff context) – catches multi-file logical bugs and style violations. - **Continuous learning**: Reads engineers’ comments on PRs to adapt to team-specific coding standards over time. - **Autonomous testing (TREX)**: Writes and runs tests in a sandbox for every PR, reducing manual QA burden. - **Enterprise readiness**: SOC 2, self-hosted on customer’s VPC, SSO, audit logs, support for air-gapped environments. - **Language support**: Full support for 12+ languages (Python, JS/TS, Go, Java, C/C++, Rust, etc.). ## Strategic Focus - **Becoming the “central validation layer”** for all code changes, especially as AI-generated code increases. - **Deepening integrations with coding agents** (Claude Code, Cursor, Codex, Devin) to make Greptile the default quality gate. - **Expanding enterprise sales** into regulated industries (defense, healthcare, fintech) via self-hosted and compliance features. - **Growing the team** – hiring across engineering, GTM, and operations (all in San Francisco). ## Why Work Here - **Culture**: Small, tight-knit team of researchers, engineers, and designers in San Francisco. High autonomy and ownership. Focus on solving hard problems in code quality. - **Work model**: All open roles are listed as “San Francisco” – likely office-first with some flexibility (hybrid). The team is described as “based in San Francisco” and “small group”. - **Perks & compensation**: Equity (0.10% – 0.30% for some roles per YC jobs), competitive salary ($140K–$160K for engineering roles). Discounts for open-source projects and pre-Series A startups. - **Engineering culture**: Building agents that autonomously validate and test code; strong emphasis on quality, security, and continuous improvement. Opportunity to shape the future of code review at scale. ## Sources 1. [greptile.com](https://www.greptile.com/) – Official product page 2.
