View company profile

We are Satalia, an enterprise AI company founded in 2008 with a mission to radically improve the efficiency of organizations and reinvent how they operate. Our journey began as a spin-off from UCL's Computer Science department, and since then, we've grown into a global team of over 100 experts with deep knowledge in AI and optimisation. We're proud to have built enterprise AI solutions for some of the world's most recognizable names, including Tesco, PwC, and The Coca-Cola Company. Our work with Tesco, for instance, resulted in what they consider the world's best last-mile delivery system, which continues to optimize 100,000 deliveries daily. We are not just about building technology; we are thought leaders in AI safety, ethics, and governance, striving to create a future where everyone is free to live beyond themselves. We are purpose-driven, working with our clients and partners to tackle some of the most significant challenges facing humanity today.

Our expertise lies in combining machine learning with optimisation to build decision-making systems that drive significant value and operational efficiency. We offer a range of solutions, from AI strategy and custom development to specific products for logistics and workforce optimisation. For example, our Satalia Delivery product optimizes vehicle fleet routes and schedules in real-time, while Satalia Workforce automates the allocation of people to their work, enhancing productivity and employee satisfaction. In 2021, we were acquired by WPP, the world's largest marketing and communications company, becoming their dedicated AI experts. This partnership has allowed us to further develop our AI for marketing, launching innovative 'Brain' technologies that help brands understand their audiences better, create content at scale, and optimize it across all channels. We are committed to pushing the boundaries of AI innovation, delivering efficiency, revenue, and growth for our clients while always considering the ethical implications and societal impact of our work.
