About Venta AI

Lucas and Stefan founded their first AI company seven years ago (later acquired) and, learning from that journey, launched Venta AI to build AI employees for sales teams. We believe organizations must harness AI to stay competitive, and our mission is to make AI accessible, compliant, and transparent for European businesses.

We raised a € 2M pre-seed round from Y Combinator, Google’s AI fund and others. Venta AI is already in productive use at a fast growing number of companies and we are currently working hard to release our third version with advanced AI-features.

Our Why

We believe AI should handle the repetitive, so people can focus on what truly matters. We’re here to help our customers win, drive innovation, and strengthen Europe’s economic power.

Our How

We work with structure, speed, and real passion. We celebrate progress, challenge each other, and boldly try new things — always focused on creating real value, not just ticking boxes.
