Episode Summary

In this episode of AI for Founders, Ryan Estes sits down with Alfonso Gómez-Jordana Mañas, co-founder of Crossmint and former Google/WhatsApp product manager. Alfonso shares how he went from building “I am not a robot” CAPTCHA to building the rails for a programmable economy. They explore AI agents as financial actors, how micropayments could reshape the internet, and why stablecoins are doubling every few months.

This conversation is a roadmap for founders, builders, and investors who want to understand the intersection of AI, blockchain, and the future of online trust.

Key Takeaways

• Identity and Trust: From CAPTCHA to Crossmint, Alfonso’s career has focused on distinguishing humans from machines and securing digital interactions.
• Programmable Economy: Stablecoins, wallets, and NFTs are the building blocks for embedded finance and AI agent commerce.
• AI Agents as Financial Actors: Agents will soon research, negotiate, and transact on behalf of humans, creating both opportunities and new risk models.
• Micropayments as Defense: Instead of fighting bots with detection, shift to economic incentives—introducing costs for interactions reduces abuse.
• Democratizing Creativity: AI tools replace mediums like watercolor or code-writing, but taste and curation remain uniquely human.
• Regulatory Landscape: New clarity around stablecoins and blockchain is accelerating adoption, but frameworks for equity and tokenized investment are still needed.
• Habit Formation Idea: Alfonso suggests programmable contracts that automatically deduct money if commitments (like gym workouts) aren’t met—an example of blockchain-enabled accountability.
• Vision for 2030: A synergistic world where humans set intent and agents execute, reshaping commerce, communication, and creativity.

Frameworks Discussed

• Intent + Verification Model: Humans express intent, AI agents execute, humans verify results.
• Economic Incentive Framework for Spam/Abuse: Reduce abuse not by detection but by shifting ROI and adding micropayment costs.
• Programmable Economy Stack:
  • Stablecoins = money
  • Wallets = storage
  • NFTs = ownership
  • APIs = infrastructure
• Programmable Habits: Smart contracts enforcing behavior through economic penalties or rewards.
