How about Microsoft? You were one of their first Office 365 resellers as well.

With Microsoft services, one exciting area is delivering big complex projects that will grow on the heels of the Azure IoT Platform.

Another growth area is Dynamics 365. Microsoft recently made Dynamics not just a CRM, but really true financial management in the cloud. They've consolidated all the pieces of those ERP solutions they bought in the last years. This is a great solution for the midmarket. There's nothing else like it.
