In this episode of Sourcery, we cover:

• Why AI is a 100x opportunity vs. past tech shifts

• The collaborative intelligence stack from semiconductors to AI teammates

• The difference between real vs. vibe revenue

• Valuations, hype cycles, and Mayfield’s investment philosophy

5 Key Takeaways

• AI is a 100x wave – Unlike the PC, web, cloud, or mobile eras, AI combines conversational interfaces and reasoning/action, unlocking a truly global expansion of creators.

• Collaborative intelligence is the future – Humans + AI “teammates” will create a $3–6T market opportunity by augmenting knowledge workers

• Valuations are overheated – Billion-dollar seed rounds are unsustainable; Mayfield stays disciplined by aligning on founder–VC win-wins

• Revenue quality matters – Durable businesses need real customers, high margins, & repeatability; “vibe revenue” isn’t enough

• Entrepreneur traits beat ideas – Authenticity, teamwork, EQ, mission-orientation, & persistence are the most reliable signals for long-term success
