One Take
The Anthropic/OpenAI enterprise revenue flip is the story of the week. 73% of first-time AI buyers choosing Anthropic — after the Pentagon standoff, after the federal contract losses — tells you that enterprise procurement teams are making independent trust judgments that don't track with government contract news. The spreadsheet angle is the practical corollary: buyers aren't adopting AI through new apps, they're adopting it through tools they already use daily. If you're thinking about where to integrate AI for your org, start where people already live — not where the demos look best.
Action item: If you haven't mapped which of your existing tools (Excel, Sheets, Slack, email) have AI capabilities already included in your license, do that this week. You're probably already paying for capabilities your team isn't using.
