Digital Scientists ranks higher on Top 11 (#1 vs #5) for Chief executives, chief operating officers and founders of US companies with 50 to 1,000 people, technology companies first, who are choosing who will build their AI into production because a pilot has stalled, an agent works in the demo and fails on real data, or their systems do not talk to each other..
