I'm Jona Schwarz. I am currently building something new in AI.

Previously, I was an engineer at Emdash (YC W26), an open-source agentic development environment with over 1 million downloads.

Before that, I worked with Zentio, Aurelius Group and Willis Towers Watson. I also built Recal, a calendar scheduling API that hit #2 Product of the Day on Product Hunt and spoke at Global AI Bootcamp Berlin.
