About a week later, the main stakeholder from that business called to say things went great, and give us insight into behind-the-scenes.
You see, that company had bought another software the year prior that had turned out to be a disaster. It didn't do what they needed it to, and there was no one to help them sort out the issues. Their CMO and team had committed tens of thousands of pounds to a software and company that was ineffective.
So, no one can blame you (or their CMO) for wanting to be certain a MarTech vendor is the right fit, really stands by the product, and will be there if help is needed further down the line.
