@davj @fabricegrinda @paultoo @naval @shervin @pioneer_fund I would guess we’ll be number 1 on this list in a few years.
@davj @fabricegrinda @paultoo @naval @shervin Hmm @pioneer_fund has 44 exits. So I'd be over 50, other Pioneer folks would be similar.
@koomen Although the racing game came out pretty well!
@koomen Super cool! I was trying something similar for a racing game for my kids but it didn’t come out this well
My all-time best investments felt both heart-pounding and uncomfortable.
Investing often means feeling uncomfortable, or sometimes even wrong, for long periods of time. When you say no to the investment everyone else is doing, or make the investment no one else wanted to touch, it's almost impossible not to question yourself. But when you're
@johnfelix123 I specifically try to notice when I’m uncomfortable and use that to my advantage in decision-making. Some of my best investments felt very uncomfortable.
@JamesUlan100 Yes one of my all time favorites
This could be so bizarrely perfect. Nathan Fielder is one of my favorites.
Thirty-four days before she reported to prison, Theranos founder Elizabeth Holmes gave Nathan Fielder and Lance Oppenheim access to document her every move. That turned into a three-year project, and A24 will release the resulting documentary this October.
h/acc - accelerate humanity
Be careful what you wish for This is why we need alignment to humankind vs any other goal
For the last few years I've wanted someone to build a time machine for the internet. I'm glad it's a portco! Nice going @ExaAILabs. This will be critical infrastructure for AI.
We built a time machine for the web. Introducing Exa Snapshot: an index of 400 billion historical snapshots of webpages that lets you search as if it's the past. Snapshot is already being used for backtesting prediction models, RL at labs, exploring the pre-AI web, and more.
When I was 13, I beat Chessmaster 4000. I remember printing this certificate and storing it, so that one day, I could show my kids. So they could see it was once possible to defeat the computer at chess.
@notkevinzhang I would try it for categorizing companies by expertise. Lots of other ideas too.

Pioneer x YC S26, in 30 seconds. Live from our database. The spinning dots: the startups in the YC S26 universe. The flying orange dots: our 500+ YC alumni joining individual investment teams. The lines: investment calls and investments.
Peak @pioneer_fund activity during the @ycombinator S26 batch was slightly... what's the word... INSANE.
@SquaredCubeRBX @pioneer_fund @ycombinator Replied!
@kamikariat @pioneer_fund @ycombinator Likewise!
One of the hot rounds in YC S26 announced today. Congrats to @robocurve on their $10M seed round led by Initialized! svpost.com/articles/roboc…
@xdavegoodwin There must be some kind of agreement with China as a next step.
This is not some stupid regulatory capture conspiracy. They are actually worried about the risks. The behaviors of the frontier labs can be explained by game theory. If any one lab slows down, the other wins, and the risk is not reduced. If the US slows down, China wins. Some game theory problems have no solution other than the extreme outcome, and thus require coordination to create a different game dynamic. Coordination is also very difficult and introduces new game theory issues (eg defection). It’s not smart to dismiss the risks as marketing stunts or regulatory capture plans.
We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our
Dario, Elon, and Sam just all publicly agreed to pace the frontier.
