After @tobi published his now-famous AI memo, you probably saw similar posts from other founders and CEOs flood this platform. But most companies are still in the “memos and demos” phase — ambitious plans and mandates, “AI-first” roadmaps on board decks, flashy features and

I met @jasonyuan in 2024 while he was building Dot at @newcomputer. I was struck by his thoughtfulness, authenticity, and deep passion for what he was building, and as I looked at what he’s created over time, it became clear that he’s a special person whose intuition allows him

Back in 2013, when I was starting Cover, I was introduced to @bryantchou. I was so impressed by his technical chops and raw intensity that I tried to hire him as our founding engineer. He politely declined to start his own new company instead, called Webflow. But we stayed in

“People [at Notion] are really only concerned about one thing which is making the product good and our customers happy. So Sesame characters are in every single conference room to remind us that it's not our own internal thumbs up that we're looking for. We're really looking to

We take Sesame Street very seriously. There's a character in every meeting room — a small reminder that we're building for the people outside the room, not the ones in it.

The demand for clean, always-on power is exploding, and the grid can't keep up. The team at Endurance Energy is going after one of the biggest untapped sources on the planet: geothermal heat beneath the seafloor. They're building systems to deliver gigawatts of zero-emission

There’s no single archetype of someone who works at @AppliedInt. But most fall into one of three buckets: The domain specialists (like AV simulation PhDs), new talent (there’s always a big cohort of recent grads) and ex-founder or CTO types (they infuse the “startup” energy, even

There are few people in the world I've met who are as dedicated, intense, and ambitious as @SurbhiSarnaSF. I had the honor of first getting to know Surbhi when we were both working at YC, and it was so obvious from my very first interaction that she was someone who would leave a

Applied Intuition has a practice called the culture table. Co-founders @qasar and Peter Ludwig, plus a few other leads (specifically, not managers) meet regularly to make sure manager bloat isn’t creeping in as the headcount has scaled past 1,000. Every six months, ICs score
