What makes an S-tier recruiter

What does it take to recruit the top 0.1% of engineers in the world — and why has talent become the ultimate constraint in AI? In this episode, I’m joined by Chris Vasquez, Founder & CEO of Quantum Talent, one of the most in-demand technical recruiting firms in the AI ecosystem. We discuss why elite engineering talent has become the core bottleneck in AI, how companies can actually attract S-tier builders, what founders get wrong about hiring, and why talent density—not headcount—is the strongest predictor of outcomes in today’s startup environment.

Highlights:

• Why AI founders are “at war” — and recruiting firms are the arms dealers. Defining S-tier talent: clear evidence of greatness, spiky abilities, and proven complexity-handling.
• Capital is abundant; talent is the true constraint in modern AI company building.
• Why companies must tell a compelling story if they lack high-signal founders or top-tier backers.
• How AI’s rapid improvement reshapes recruiting needs — fewer engineers, but far more specialized ones.
• The Sequoia-backed company that failed to hire until they raised their comp bands. (7 declines vs. 17 hires after fixing comp.)
• Why founders should overpay strategically for the roles that matter most.
• Key signals elite engineers look for: founding team quality, investor pedigree, mission clarity, and market upside.
• Why “experience with greatness” de-risks execution in early-stage teams.
• The #1 heuristic Chris wishes he learned earlier: “If you wouldn’t hire 100 of that person, don’t hire one.”
