AI-Powered Code Review

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

We built an AI that reviews Pull Requests to find bugs and risky code changes. It's trained on millions of code contributions and helps engineering teams ship faster with higher confidence.

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

We live and work in Stockholm, Sweden. After YC, the company would still be based in Stockholm.

Explain your decision regarding location.

Stockholm has a strong engineering talent pool and a vibrant tech community. It's where we live and built Codeball, so we want to keep building here.

Frequently Asked Questions

Is this the real Codeball YC application?

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