Episode notes
Rebuild Org To Match AI Augmentation
- Do redesign your org from first principles around the capabilities you need with AI augmentation, not around arbitrary headcount targets.
- Block took a blank sheet, defined the roadmap and required skills, then built the org to match, choosing reinvestment over pure cost cuts.
Cuts Came From Role Needs Not Targets
- The 40% reduction was outcome-driven, not target-driven: Block built up required roles to maintain stability, compliance, and its roadmap.
- Jennings emphasizes discipline-level automation differences, with product development most affected.
Centralize Functions To Create Centers Of Excellence
- Functionalizing Block centralized engineering, design, and product to create centers of excellence and reduce duplication across Square, Cash App, and Afterpay.
- Jennings pairs that with a strong DRI model so projects keep decentralized speed with centralized quality.
