We’re launching @JudgmentLabs today and announcing $32M in funding. As AI agents take on more of the work that creates economic value, they generate massive amounts of production data: the clearest record of how they behave with users, software, and the real world. Judgment builds infrastructure for improving AI agents from production data.










The best part of our job is finding truly out-of-distribution people—the ones you know you’ll be in business with for life. A lot will be said about how exceptional @bfspector , @amspector100 , and @aidanmantine are as founders—there’s little debate there. What matters even more is who they are as people. They’ve pushed me and the @novaholdings team to think bigger and work harder. We’re lucky to call them close friends. Getting to wake up every day and help them pursue a mission we believe in is a privilege we’ll never take for granted. @flappyairplanes take off !



Data centers dominate AI, but they're hitting physical limits. What if the future of AI isn't just bigger data centers, but local intelligence in our hands? The viability of local AI depends on intelligence efficiency. To measure this, we propose intelligence per watt (IPW): intelligence delivered (capabilities) per unit of power consumed (efficiency). Today’s Local LMs already handle 88.7% of single-turn chat and reasoning queries, with local IPW improving 5.3× in 2 years—driven by better models (3.2×) and better accelerators (1.7×). As local IPW improves, a meaningful fraction of workloads can shift from centralized infrastructure to local compute, with IPW serving as the critical metric for tracking this transition. (1/N)

One year ago today, I cold outreached @Henrymlien . Within 15 minutes of our first coffee chat, I was already convincing him to join us on a new adventure. A year later, it’s clear that nothing we do today would be possible without him. Anyone who’s had the chance to work with Henry knows his work ethic and passion are truly out of distribution. Thank you for taking a bet on us, Henry. At just 19, the world is already yours. Here’s to the next hundred. @novaholdings


In middle school, with money earned performing magic shows I opened my first investment account. At Stanford, captivated by the markets, I realized a paradigm shift was on the horizon. Today, I am excited to announce our $5.7M raise, led by @novaholdings. With the developments in AI, I knew I could no longer wait to start @vigillabs. At Vigil, we are building the engine to understand markets in realtime, designed for our own traders.
