📝 EPISODE DESCRIPTION

Dhanji R. Prasanna is the chief technology officer at Block (formerly Square), where he’s managed more than 4,000 engineers over the past two years. Under his leadership, Block has become one of the most AI-native large companies in the world. Before becoming CTO, Dhanji wrote an “AI manifesto” to CEO Jack Dorsey that sparked a company-wide transformation (and his promotion to CTO). *We discuss:*

1. How Block’s internal open-source agent, called Goose, is saving employees 8 to 10 hours weekly
2. How the company measures AI productivity gains across technical and non-technical teams
3. Which teams are benefiting most from AI (it’s not engineering)
4. The boring organizational change that boosted productivity even more than AI tools
5. Why code quality has almost nothing to do with product success
6. How to drive AI adoption throughout an organization (hint: leadership needs to use the tools daily)
7. Lessons from building Google Wave, Google+, and other failed products

🧾 EPISODE SUMMARY

In this episode of Lenny's Podcast, featuring Lenny Rachitsky and Dhanji R. Prasanna, Dhanji Prasanna: How Goose agents save Block 10 hours a week explores inside Block’s AI Revolution: Goose Agents, Culture Shifts, Real Productivity CTO Dhanji R. Prasanna explains how Block became one of the most AI‑native large enterprises, centered around their open-source AI agent platform, Goose. Goose and its mobile cousin Gosling are already saving employees roughly 8–10 hours per week on average in AI-forward teams, with early data suggesting 20–25% manual hours saved company‑wide. The transformation wasn’t just about tools: Block redefined itself as a technology company, reorganized from GM-based business silos into a functional org, and pushed leaders to personally use AI in their daily work. Along the way, Dhanji shares counterintuitive lessons on org design, when not to build tools, and why code quality is largely orthogonal to product success.
