80% of enterprise revenue from 1% of customers — catastrophe or TAM?
Ramp found 80% of OpenAI and Anthropic's enterprise revenue comes from just 1% of their customers (with the caveat that Ramp's data skews toward tech-forward early adopters). The obvious read is concentration risk. But unless you believe that 1% has use cases totally dissimilar from everyone else, the other read is that the remaining addressable market is absolutely enormous.
