We've done many different projects where we have integrated things like Salesforce and Hubspot. For Nordic Semiconductors we created an entirely bespoke ticket application that integrates support engineers directly into the community. From this we created a generic Ticket Application that is used on the a recent Verint site that both 3 Sides and 4 Roads collaborated on. If you are interested, message me and we can give you a demo of what it can do.
