It has been really easy for us as marketers, having one platform that can manage all our campaigns (both B2B & A/A) in an integrated way with CRM integration so we have 1 view into what's happening across both channels! The support team are very helpful when needed - not always something you get from some other platforms out there but they're top notch anyway :) Nothing at this stage though? Would love more integrations like Zapier or similar which would make life easier even further down road too I believe!! We've had success integrating it within Salesforce via Journey Builder where members sign up / login using their own credentials rather than being directed through O365 etc..
This then feeds straight back directly onto HubSpot account giving them details about customer journey right throughout funnel process helping deliver personalised experiences along path towards becoming future clients!
