It's model routing
Think through this situation: "A founder pushes back hard on your cost recommendation in the values round. What response best demonstrates the truth-seeking they're screening for?" Give the practical answer in plain words.
Step 1 of 2
When pushed, engage the substance. State your reasoning, ask what evidence would change their mind, offer what would change yours.
Folding instantly reads as low conviction; digging in past the evidence reads as low ego control.
Have a real example of changing your mind when the data contradicted you.
“I was sure the migration would pay back in two quarters; the utilization numbers said four, so I rescoped it” is the shape they want.
High ownership without claiming the team's work. In a flat org with no thick management layer, you escalate by earning trust, not by org chart.
Name a failure you owned cleanly and what you changed.
A founder can smell a generic answer. Have a genuine reason FinOps-for-AI at Cursor's scale is the problem you want next.
Tie it to the unsolved nature of the problem, not to the company's logo.
“I think the most impactful cost move isn't squeezing utilization - it's model routing. Most completions are simple and don't need the biggest model. If we route by request complexity, we cut cost per inference without touching the latency users feel. I'd want to validate the complexity classifier's error rate before betting on it, but that's where I'd start.”
Bring one strong, defensible opinion about Cursor's cost or product strategy and bring the conditions under which you'd abandon it. Stating an opinion shows conviction; naming what would change your mind shows truth-seeking. That pairing is exactly the value they're screening for, demonstrated instead of claimed.
