At Flexciton, we work with high-tech factories built with investments worth hundreds of millions of dollars, producing advanced chips at the atomic level. It can take up to nine months to fabricate these cutting-edge products.

We are proud to be the only SaaS product in the world that plans and schedules production in high-tech semiconductor fabs, using complex algorithms in real-time, all from our London office.

Our technology consistently delivers the best production schedules, and leading companies like Seagate trust Flexciton to run their production 24/7. With operations across the US, Europe, and expansion into Asia, we are on a path to realise our vision for the Autonomous Factory.
