03 / The idea

From the team
at Astra AI

The way we build
software has changed.

The conversation in Ljubljana
should change with it.

Most of the code we ship at Astra is written by models. Our engineers spend their time on architecture, review, and the systems that produce and verify that code. A small team can now build things that used to take a department.

We wanted to bring that conversation into one room. People who deploy this stuff in production. The tools they use. The decisions they make. What actually works.

We were also there to meet great engineers in the region, and hopefully work with some of them. That’s why we put on this evening with Vercel.

Thank you, Ljubljana.— The Astra AI team

04 / Thank you

The evening is over.
The conversation isn’t.

Thank you to everyone who joined us at Odiseja on 22 September, and to Guillermo, Lars, Tjaž, Boris, and Klemen for sharing how they build.

Event concluded

Let’s keep
building.
