How Does Claygent Achieve Running 5,000 Rows in Under a Minute? Technical Insights Requested

Hey, I have a technical question regarding Claygent. Multiple people I talked to claim that Claygent can run 5k rows in less than a minute. That's an insane number. Does anyone understand (technically) how Clay does it? What's the concurrency level for the agent, what does the unit economics look like and so on.
