A services company needs the same things as any other: people, customers, invoices and contracts. They usually end up in several different tools that nobody connects, and someone copies hours from one into another at the end of every month.
Keystone puts them in one modular platform. It also covers something specific to a cloud company: engineers reach the cloud consoles of every customer from one page, with rules about who may enter which.
We wrote Keystone to run Magicorn: our people, our customers’ service plans, our invoicing and our access to cloud accounts.
