Cooper Hollmaier

Senior Product Manager | Growth • Platforms • eCommerce

I build platforms and growth capabilities that empower teams, enhance customer experiences, and deliver measurable business impact.

Core Philosophy

Bias for action: Better to make a bad decision and learn than no decision at all.
Challenge the norm: Don't accept low quality simply because that's something others have accepted.
Strong opinions, loosely held: Push hard for what you believe until evidence proves otherwise.
Scaled impact: If something works, build it once and use it everywhere, don't solve the same problem team by team.
Clarity is critical: Align the room around one validated customer problem instead of 4 unvalidated ones.
