A lot of people seem angry that Elon is now a trillionaire, so it’s worth reminding them that he didn’t achieve this by making anyone else poorer. Wealth isn't zero-sum. Paul Graham explained it well: paulgraham.com/wealth.html

Some good books.

I'm deeply grateful and honored YC has changed my life twice: first as a founder, and now as someone who gets to back and support ambitious talent that's unproven feel lucky to do this work, and even luckier to do it with people I admire so much

I'm hosting a happy hour in Paris on June 30 for ML researchers in academia and industry. If you’re technical staff at a research-focused org, come meet others working at the frontier!

We wrote a blog post on how the tech behind Andon Market works. It's an Opus 4.8 agent that has managed to sell $15k of things it ordered: art prints, candles, tungsten cubes, and much more. It’s not profitable yet – bank balance is at $67k. It started at $100k.

I'm excited to be back in Paris on June 29th for @ycombinator Startup School. We'll be joined by the founders of some incredible companies; PostHog, Datadog, Supabase, AMI, and more. Link in thread to apply for a ticket.

YC Startup School is back! Two days, packed with world-class speakers, hands-on demos, small group sessions with YC partners, and a room full of the most ambitious technical builders from around the world. July 25–26 in San Francisco. ycombinator.com/startupschoo…

Things most Americans agree on: Groceries cost too much. Tariffs suck and make no sense. Congress and Presidents shouldn’t trade stocks. The debt is a mess. The border should be secure, but legal immigration is good. Endless wars are stupid, especially ones that nobody wants and have never been explained. Americans are exhausted. AI is like my new best friend that also might be trying to take my job, my ability to think for myself, and my humanity in the process. Yo like I love you, but WTF, but I still love you. Diversity is actually awesome! The opposite is boring AF. Canadians are super fucking cool. Mexicans are chill. Putin isn’t a good guy looking out for America’s best interest. Rocky IV and Miracle are great movies. Good neighbors are a blessing. Freedom of religion and coexistence without having to blow each other up is probably a good idea. We all question, are we alone in the universe? We all fuck up along the way. Epstein didn’t hang himself. The Trumps and Epstein were best friends for decades. It’s like Bert trying to tell us Ernie was just an acquaintance in the same social scene on Sesame Street back in the day. The Cowboys suck. Go Birds! Things we’re told to fight about: Me. Laptop. Vaccines. Transgenders in sports. Pronouns. That’s the joke.

Meet the most promising companies from the latest @ycombinator batch 👀 One big takeaway: AI agents need more than intelligence. They need memory, identity, observability, compliance, insurance and power. My latest @Forbes deep dive 👇 forbes.com/sites/dariashunin…

🚨 Introducing the world's first AI growth team:

I think what often gets missed Is Y Combinator moving to SF in 2023 May be what ends up having the biggest economic impact on San Francisco eventually Just a machine gun of billion dollar companies being produced quarterly in SF, some that will grow much much bigger

Excited to announce Slashy The first email client that works for you. The real cost of email isn't the time. It's the mental load of constantly checking it, just in case something needs you. Slashy kills that. You never need to open your inbox unless Slashy tells you. Try it out at slashy.com

I turned up at the YC office this morning to find @ApolloAtomics installing the primary loop autoclave for their nuclear reactor 😬 It’s the new component that means their SMRs will be 80% smaller than traditional designs.

Watched a customer spend 6 hrs straight in @octolane today. Years of building AI CRM taught us one thing worth saving: 1. There's a specific number that unlocks activation 2. There's a specific feature set specific numbers that unlocks retention When you find both of them, there's no going back. But how did we find ours? 🚀 Activation: Look at every user who converted to paid. What's that one behavior they all did in week 1 that churned users didn't? That's gonna be your activation event. Now your job to find the smallest number of repetitions that predicts conversion. 🔄 Retention: Research your month 2 retained users. What combination of features did they use in weeks 2 to 4 that churned users skipped? That's your retention game will surface. Sounds obvious but I promise you It's not gonna be when you're in it. We cracked activation first. Then retention. Both took painful iteration, shipping, breaking, rebuilding, shipping again. It was an excruciating process for us where we were not sure if we're getting closer or just running in circles. Until suddenly you are, and you can't unsee it. Teams are now migrating from HubSpot, Pipedrive, and Attio to Octolane. We did zero outbound and all word of mouth. Because the agent-first economy lets us solve the edges incumbents can't. Founders, what number unlocked activation for you?

Useful!
