Shyam Sankar is Palantir's chief technology officer and the man most responsible for making its business and technology work. He joined in 2006 as employee #13, when Palantir was one of Silicon Valley’s freakshows: a small and somewhat demented chickenhawk of a startup with a buggy demo and no customers. For 20 years, largely from the shadows, he has brute forced it into the spearhead of "defense tech" and a $320 billion company. He embedded with intelligence analysts in Virginia, special operators in Iraq and Afghanistan, and on the factory floors of some of the world’s biggest companies—building and rebuilding software in the field, sometimes with phones taped to his head so he could give and take feedback while keeping his hands free to code. He invented the “Forward Deployed Engineer,” which has since become the object of both skepticism and imitation. Alex Karp, Palantir's mercurial co-founder and CEO, says the company would not exist without him. The same can be said of the modern defense tech industry, many of whose founders cut their teeth working for Shyam. In this deeply reported profile, @JeremySternLA tells the story of the most pivotal but hidden figure behind America’s most controversial company. He also gives the clearest explanation you'll read of what Palantir actually does, whether its valuation is justified or absurd, and what any of this has to do with the company’s mission to save Western civilization. It begins in the Grand Ballroom of The Pierre hotel and winds through Nigeria and India, Florida and California, Iraq and Afghanistan. It ends with a rabbi, a monkey, and a lesson in what it means to buy time in the face of a coming fire. Only in Colossus:

Announcing Series C We’ve raised $1.4B, valuing the company at over $14B With this capital, we will accelerate our mission to build omni-bodied intelligence 🚀 skild.ai/blogs/series-c




Today, we’re excited to announce our $150M Series A at a $1.7B valuation—nearly 3× our May seed round. Since launching evaluations in Sept, our annualized consumption run rate has surpassed $30M. Our mission is clear: to measure and advance the frontier of AI for real-world use, ensuring that developers, researchers, enterprises, and everyday users can understand how AI behaves where it matters most. The round was led by @Felicis and UC Investments (@UofCalifornia), with participation from @a16z, @TheHouseFund, LDVP, @kleinerperkins, @lightspeedvp and @LaudeVentures. This milestone reflects a growing industry consensus: AI cannot scale responsibly without independent, transparent, and continuous evaluation. Over the past year, LMArena has become the world’s most trusted community platform for understanding how AI models perform in real-world conditions. As AI reaches billions of people across the globe, the need for measurement grounded in lived experience—not benchmarks alone—has never been more urgent. Today, we serve more than 5 million monthly users across 150 countries. Together, our community generates over 60 million conversations every month, evaluating model capability and reliability across text, code, image, video, and search. We will move even faster to build new features and improve our product experience for the community to evaluate the frontier of AI. This unprecedented engagement signals a fundamental shift in expectations: the world now demands AI that is measurable, comparable, and accountable. This new funding allows us to meaningfully scale our engineering, research, platform operations, and community initiatives to meet accelerating global demand. With our team, partners, and global community behind us, we’ll keep redefining how the AI frontier is measured and advanced—on our path to building the world’s most trusted evaluation platform.
