It’s a risky play. At my enterprise company, we’re not allowed to use a single vendor for everything, we explicitly must use different companies if a favoured vendor hits a certain spend threshold.

This is to prevent cost overruns and solution capture, where every solution to your company’s problems becomes “give it to X vendor” and then X vendor kills a product line and you’re toast.

Salesforce needs to be careful or else they’ll hit that threshold where companies don’t want to use them because you as a client are too small. Google is facing this problem right now.
