Strum AI
At Strum, we're reimagining technology that powers global supply chain using a fresh AI-first approach. Most supply chains are still stuck with Excel or enterprise tools that take months (and $MM) to adopt. Our mission is to lower that barrier — making it possible for any business, big or small, to access modern forecasting, inventory, and planning solutions in days, not months. We’re on our journey to democratizing supply chain technology.
