What Sourcebot does

Sourcebot is an open source code understanding platform for massive codebases. We’re used by thousands of engineers in some of the largest companies in the world, including NVIDIA, Red Hat, Wikimedia, and Arista Networks. Understanding code, not writing it, is the primary bottleneck for large engineering teams. For developers, this means onboarding onto complex codebases faster. For AI agents, it means getting the necessary code context to minimize hallucinations and maximize cohesion within the wider codebase. Sourcebot solves this by giving developers and AI agents the ability to regex search across millions of lines of code instantly, as well as ask questions across thousands of repos using any flagship reasoning model. Being open source and on-prem, we can get deployed in enterprises within minutes before other tools even get approval. We met a decade ago at McGill University and have been building together full time for over 2 years. We’ve personally felt the pain of understanding large codebases while working at Microsoft, EA, Ubisoft, Google, and Meta.

Helping humans and AI agents understand massive codebases

What is your company going to make? Please describe your product and what it does or will do.

We're building an open source platform that helps developers and AI agents understand large codebases. Our product allows instant regex search across millions of lines of code and lets users ask questions across thousands of repositories using powerful reasoning models. It deploys on-prem quickly so enterprises can approve it faster than other tools.

Where do you live now, and where would the company be based after YC?

We currently live in San Francisco, CA, and the company is based here and would remain here after YC.

Explain your decision regarding location.

We live in San Francisco where a lot of our customers and potential partners are, plus it's a hub for AI and developer tooling startups. Staying here makes sense given our connections and team location.

Frequently Asked Questions

Is this the real Sourcebot YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Sourcebot's public data (launch notes, founder backgrounds, product description). It shows how a company like Sourcebot would present itself to YC, not the text they submitted.
