500+ founders. 1,500+ nominations. 100 companies. The Black Flag 100 is back 🏴☠️ The premise is simple. Founders know who's building the next great companies, so we asked them one question: "Which early-stage companies are you most excited about right now?" (Only rules: Out of stealth in the last two years, not on last year's list) We tally up the 100 most-nominated companies and the BF100 for 2026 is ready to set sail. The list also celebrates the great investors backing these companies. Here's what they're building: 🛡️ 27% Defense 🚀 22% Aerospace 🤖 22% Robotics & Manufacturing 🧠 19% AI And where: 🌉 40% Bay Area 🏖️ 20% SoCal 🗽 18% East Coast 🤠 8% Texas Hard tech. Hard problems. The next generation of critical technology, being built mostly on the coasts and increasingly everywhere. To every founder on the list, and every founder still out there chasing storms over certainty: keep building. We need you. It's a pirate's life 🏴☠️ Full list in the comments.
