Senior🎓
Top SchoolAlex Ziehm is a Senior Product Manager specializing in global fraud risk and payments, with nine years of cross-functional experience building ML-driven defenses, onboarding flows, and billing products. At Square he led teams of engineers, ML scientists, designers, and policy experts to launch LLM-backed scam detection that cut scam-email complaints 30% while maintaining >99% precision and expanded fraud models across markets to recover losses after attacks.

Comfortable bridging technical and non-technical stakeholders, Alex also fosters team culture and community engagement in Mexico City, bringing product rigor from startups to large fintechs and a systems-engineering background from University of Virginia.
