Greptile, a startup that aims to teach Large Language Models (LLMs) to answer hard questions in plain English about large real-world codebases, has announced its $4.1M seed round led by Initialized Capital, with participation from angels including Rich Aberman and JJ Fliegelman. The company believes that software engineering is difficult not because of the complexity of incremental code but due to the lack of understanding the wider context of the codebase. Greptile's novel approach to indexing and searching large codebases mirrors how experienced engineers do it, allowing developers to use a chatbot or API to answer nuanced questions about their company's codebase. The AI expert can support tasks such as reviewing merge requests, diagnosing bugs, and updating internal documentation, making it an essential tool for software teams with unique processes. With its single API platform, Greptile provides a flexible solution that can be easily configured into any type of AI dev tool, creating cohesion across different tools and applications. The company's founding team is highly technical, small, and always shipping, and they are actively recruiting programmers interested in building tools to help developers get more out of their software development lifecycle.
