Vlocity is close to the Veeva model and for good reasons.
Many of the founders of Veeva started at Siebel where they worked on vertical market solutions. They migrated to Vlocity whose business model is Veeva+1. Actually it’s already Veeva+4 (verticals) and the model is set to expand. If founder and CEO David Schmaier has his way, the number will be about 24 which is the number of verticals whose development he supervised at Siebel.
