Who We Are

Tacto is an AI-driven procurement platform. Our mission is to strengthen Europe’s industrial “Mittelstand” by future proofing their supply chains. We streamline how companies buy, negotiate and manage procurement – we help them optimize their by far largest cost driver to stay competitive in the long-run. Trusted by hundreds of companies, Tacto transforms procurement into a strategic advantage.

Based in Munich, our team of builders, entrepreneurs and industry experts is creating technology that truly matters. We’re backed by some of the best investors in the world including Sequoia Capital, Index Ventures, Cherry Ventures, Visionaries Club, UVC Partners as well as the founders of Personio, GetYourGuide, Helsing & Forto.

Why It Matters

The industrial Mittelstand – 90,000+ small and medium-sized enterprises – forms Europe’s economic backbone, driving 25% of Germany’s GDP and providing over 30% of jobs. These hidden champions manufacture the physical world around us, from the machines that build our cities to the medical devices that save lives.

Today, a world of growing uncertainty and disruption is threatening their position. To stay competitive, the Mittelstand must unlock new efficiencies – and procurement is their largest, strategic lever to do so.

At Tacto, we deliver tangible cost savings and strategic resilience at a time when it’s needed most. Our work extends beyond technology – it’s about protecting the foundation of Europe’s economy for generations to come.
