How do I negotiate compensation without damaging my relationship with the recruiter?

Frame it as a partnership. You're not making demands — you're asking how you can both align on long-term incentives. Most recruiters expect candidates to negotiate, and they're your advocate internally. Use language like: "I'd love to partner with you to find something that works for both of us." Show gratitude throughout the process. A recruiter who likes you will push harder for you behind the scenes.
