Investing in builders @accel and @ucberkeley. Magic is just spending more time on something than anyone might reasonably expect. Nobody gets my movie references

Spent a few days in El Segundo last week. It's an easy-to-miss spot near the beach. Nothing flashy. Just warehouses, big doors, steel buildings. You can smell and hear the hum, sparks, smell of metal and resin. Nobody talks about "disruption" or "changing the world" here. It's…

Dan invested in Scale two months after I joined Accel. What a journey to witness end-to-end, led by an impossibly bright young CEO in @alexandr_wang, who drove the AI revolution with a force of nature culture & company. Special week for Accel with two ~30B outcomes (h/t @circle)
We’ve been fortunate to partner with @alexandr_wang and the @Scale_AI team since the days when they were working out of @daniel_levine’s basement. Thanks for bringing us along for the ride, and here’s to what’s next. 🚀 Read more about Scale, Meta, and our continued partnership…

San Francisco is cleaner and more pleasant than at any point over the last 5 years. Just went for a walk on Valencia and it was awesome. It’s nice to see elected officials delivering. 👏 @DanielLurie
