I'm organizing an incredible group of optimists to host the 2035 Worlds' Fair — the kind of World's Fair that we only read about in history textbooks. Even before San Francisco hosted the 1915 Panama-Pacific International Exposition, our fair city has been the Frontier — the place where dreams become reality. In 1915, the SF Exposition introduced the world to modern marvels like the telephone, the car, and the airplane. Since then, we've created the Internet, smartphones, movies, reusable rockets, self-driving cars, and mRNA vaccines. The Worlds' Fair 2035, San Francisco, will celebrate our shared progress, and introduce the world to what's next. We'll also celebrate: the 90th Anniversary of the U.N., on the stage where it was created; the 100th Anniversary of the Social Security Act, at America's finest public university; the 65th Anniversary of the Summer of Love, at the amphitheater where it started; the 1st Public Demonstration of the U.S.S. Enterprise, America's most advanced nuclear vessel, at Starfleet HQ; and more. With the support of our donors, we will construct the Next Great American Monument, right in the middle of San Francisco Bay. We will construct a new "Statue of Liberty of the West," a new monument honoring American values. The San Francisco Worlds' Fair Company is a publicly-held California non-profit corporation. Right now, we're competing for the 2035 International Exposition bid against Shenzhen, China (and nobody else.) You should vote for us, because we guarantee a Worlds' Fair worthy of the World's Fairs of old. The 2035 Worlds' Fair will celebrate the scientific, artistic, technologic, and societal progress that humanity has created on Earth in the last 120 years, and it will showcase the world of the future. If you've ever seen pictures of those glorious World's Fairs, like in Chicago, San Francisco, New York, London, Paris, and Vienna: that's what we're building. Join us. Read more: 2035expo.com

Partner & Head of Operations
2015 - 2022
SignalFire is what happens when AI nerds run a VC firm. We've built unique technology to identify and empower exceptional founders in ways that a traditional VCs still can't imagine. My review, as a founder: ⭐⭐⭐⭐⭐ As the first Associate, then a Principal, then Partner, I invested in the next generation of AI technology, augmented AI systems, legaltech, and fintech (incl. blockchain & digital assets) As Head of Operations, I built and ran the back office of our SEC-Registered Investment Adviser from $0 to $3B+ AUM. I executed 650+ investments (60%+ as the lead investor), raised 35 funds, and managed finance, audit, legal & fundraising to get us from 0->1. Today, we're much bigger, and we're one of only ~20 US VC firms to be a fully ILPA-compliant RIA — and we're still the only firm that's AI-native. Read more: signalfire.com
