We understand from sources that this funding has been raised at a $500 million valuation, which is a huge hike.

To date, AppZen’s biggest product has been a service that automatically audits expenses — comparing, for example, an employee’s charges with travel that person has undertaken (along with many other data points) to see if the charges match up; as well as making sure the expenses are compliant with company policies and raising flags when they are not.
