# Head of AI > Head of AI Ltd (UK company 15915080) builds an end-to-end AI operating system for ambitious professional firms. We find the work AI should do, build it into the firm's own workflows and run it, led by a fractional Chief AI Officer, so the firm does more with the same team and is worth more when it sells. First working prototype is typically live in 30 days. Based in London, working with UK firms. Contact: info@headofai.ai, 020 8102 0620.
