Greptile

The Senior Engineer Who's Read Every Line of Code

Every developer knows the feeling: you're reviewing a pull request, but the change touches code you've never seen before. You don't know what depends on it, what assumptions it makes, or why it was written that way. Greptile is solving this with an AI code review agent that has read and understood your entire codebase — not just the file being changed.

Founded by Daksh Gupta, Soohoon Choi, and Vaishant Kameswaran — three Georgia Tech computer science graduates — Greptile emerged from Y Combinator's W24 batch with a mission to give every development team access to a reviewer with complete institutional knowledge. The result is an AI agent that integrates directly with GitHub to flag bugs, surface hidden dependencies, and explain complex code in plain English.

What They're Building

Greptile connects to your GitHub repositories and indexes your entire codebase to build deep semantic understanding of how the code fits together. When a pull request is opened, the agent reviews it with that full context — identifying issues a file-level reviewer would miss entirely. It surfaces cross-codebase dependencies, catches subtle bugs introduced by changes in one area that break assumptions in another, and explains what's happening in clear, natural language.

The platform has attracted 500+ paying customers including Stripe, Amazon, PostHog, and Raycast — teams that have seen their PR merge times improve by 4x. With 20 employees and backing from Initialized Capital, Greptile is scaling quickly to meet the demand from engineering teams that want faster, more thorough code review without growing their headcount.

Why It Matters

Code review is one of the most expensive bottlenecks in software development. It's slow, inconsistent, and degrades in quality as codebases grow. A reviewer who has only seen part of the system will miss bugs that a senior engineer with years of context would catch immediately. Greptile's $4.1 million seed round is funding the infrastructure and team needed to make that depth of review available to every engineering organization — regardless of team size or codebase age.

About Daksh Gupta, Soohoon Choi & Vaishant Kameswaran

Daksh Gupta (CEO), Soohoon Choi (CTO), and Vaishant Kameswaran are the three co-founders of Greptile and are all graduates of Georgia Tech's computer science program. Their shared background in CS gave them both the technical foundation to build sophisticated AI tooling and the firsthand experience of the code review problems that engineers face daily on large, fast-moving codebases.

The team went through Y Combinator's W24 batch, where they sharpened Greptile's product around a deceptively simple insight: most AI coding tools only see a slice of the codebase at a time. By indexing the entire repository and maintaining that context during review, Greptile's agent can reason about changes the way a principal engineer would — understanding not just what changed, but what it touches and what could break.

With backing from Initialized Capital and angel investors including Rich Aberman (WePay) and JJ Fliegelman (WayUp), the trio has grown Greptile to 20 employees and 500+ paying customers. Their traction with companies like Stripe and Amazon reflects the strength of their technical approach and the clarity of their focus on the code review workflow specifically, rather than trying to be a general-purpose AI coding assistant.
