Since he is the RevOps guy, my first question would be how much is this going to save.
Once you go to buy Google Workspace + Slack + Zoom + Jamf + all the other replacements. I doubt it is going to be any cheaper.
--Edit to add. He says you need Gemini so you can be a AI company. Doesn't the Microsoft subscriptions come with CoPilot?
Microsoft Copilot is for all intents and purposes thoroughly useless. It has a 8k char limit and the file upload feature is abysmal.
