Soohoon Choi is a South Korean-American software entrepreneur and co-founder of Greptile, an artificial intelligence company that builds tools to help software engineering teams review, analyze, and understand codebases. Based in San Francisco, Greptile was accepted into the Y Combinator Winter 2024 batch and has raised a total of $30 million in venture capital funding.[1]
Career
Choi studied computer science and mathematics at the Georgia Institute of Technology, graduating in 2023 with degrees in both disciplines.[2] While at Georgia Tech, Choi and his co-founders Daksh Gupta and Vaishant Kameswaran participated in the university's CREATE-X Startup Launch program. The team initially developed an AI-powered customer feedback tool called Tabnam but pivoted after the program's customer-discovery process revealed stronger potential in applying their technology to software development.[3]
Greptile, launched in 2023, builds AI agents that review pull requests in GitHub and GitLab with full contextual understanding of a project's entire codebase. The company's core product uses large language models to analyze code changes, catch bugs, and provide context-aware inline comments during the code review process. Greptile can be deployed via the cloud or self-hosted within a customer's own infrastructure.[4]
The company raised $4.1 million in seed funding from Initialized Capital in 2024.[5] Later that year, Greptile raised $25 million in Series A funding led by Benchmark, bringing the company's total funding to $30 million and its valuation to $180 million.[6]
As of 2026, Greptile serves over 2,000 customers, including companies such as Brex, Substack, Scale AI, Klaviyo, PostHog, and Whoop. The company reports that customers using its platform merge pull requests four times faster on average.[7]
