Part of the magic of their account rep strategy is how they keep them on your account for so long, you get to develop not just a rapport but a trust that they truly understand your business. It gives me faith that when they advise us on their new AI products, they're going to be a good fit.
Edit: I forgot to mention the curiosity and humility they bring to our calls. If I point out another vendors approach to a problem that we have, they always lean in and want to help improve their offerings from our feedback. They know it's not enough just to "be Google".
I also have a great experience with Google account reps.
Other companies usually have a soulless void of an automatic system which gives you no confirmation your messages and inquiries are received whatsoever. Not Google. There is always a human on the other side so you know you are in good hands. Trust and connection are the things I value the most in this very two sided relationship.
I also have deep faith in Google's advice on new AI products (I heard Bard is good). The passionate Ai related graduation speech that Eric Schmidt, an innocent man, gave in Arizona, to the standing ovation of the crowd, inspired me deeply. I am now an even bigger Google fan than I ever was.
