Kevin Armstrong

I'm a payments product leader with a track record of building and scaling secure transaction networks at companies like Amazon, SpaceX, and Capital One. Over the past decade, I've shipped high-impact payment systems, led cross-functional engineering loops, and designed merchant infrastructure used by millions of users daily.

Interviews for Product Manager roles at major tech organizations are notoriously opaque. Having sat on both sides of the hiring table at Amazon and SpaceX, I started Armstrong HoldCo to provide direct, honest, and actionable coaching for PM candidates looking to clear the bar.

My coaching philosophy is simple: no generic frameworks or fluff. We focus on real system design, technical commerce intuition, behavioral stories with true depth, and mock loops that mimic the exact rubrics used by Top-tier tech recruiters.
