E.g. I've been in meetings with multiple developers who, if you add up everyone's salary, is well over $1 million/year, debating for way too much time on whether it's worth it to buy a $500/month service to help automate some aspect of devops.
Maybe this wasn't the case for your specific anecdote, but in the scenario I'm describing I got the feeling that a lot of people think about business purchases in the context of their own personal finances rather than in the context of the business's finances. Leading people to be extremely cautious with things like a $10k purchase that would be "expensive" if purchased as an individual and "cheap" if purchased as a company.
In those cases, getting an exec to come in and pull the trigger can help. The exec is used to looking at big picture budgets/strategy, which IC's aren't. (Although I'm sure someone here can come up with another anecdote proving that wrong)
