Introducing Mirai, the world’s first virtual neighborhood tour, backed by a16z @Speedrun. World models are going to change how we experience the physical world. We’re building the application layer to enable that. Our first deployment is real estate, for agents, brokerages, property platforms, and developers. Mirai turns any address into an explorable simulation of the surrounding neighborhood. Walk the streets. Visit the nearby café. Explore the park. Follow your commute. See what your day-to-day life there could actually look like before you move.

Today, we're killing the billable hour for patent work. Fearn Legal (@fearnlegal ) is a modern patent firm built from the ground up on our own operating system, FearnOS. What that means: → Flat fees, not hourly billing → Drafts in days, not months → Experienced patent attorneys reviewing every application → One platform for your entire portfolio, with permissions you control If you're building something worth protecting, we'd love to help.

Today, we’re launching an ambitious new school called The Horowitz Andreessen Academy. Based in San Francisco, The Academy serves the most promising young high school graduates. We think this can be an elite institution that attracts top tier talent. One that prepares students for the future rather than remaining stuck in the past. The #1 goal is to help students learn to build, which is the most important skill in the AI era. They'll learn primarily by pursuing their own projects, either individually or in groups. There are classes and guest lectures, too, from some truly amazing people who have built modern-day Silicon Valley. The Academy is designed as a network, since that’s the reason students go to school in the first place. Core to that network are our 10 Founding Partners: Anduril, Anthropic, Coinbase, Google, Meta, NVIDIA, OpenAI, Palantir, Replit, and Stripe. The network includes over 50 hiring partners and over 200 speakers and mentors. To join as a hiring partner or faculty member, you can apply on our website. We raised $42M in funding led by @a16z. I'll be CEO and @pmarca and @eriktorenberg will join me on the board. Applications are open for our Founding Class Fellowship, which will be one year and tuition-free. Eventually, pending regulatory approval, we plan to offer a two-year program that charges tuition, similar in cost to an elite private university. We're looking for the most unusually ambitious young builders on the planet. Come join us in San Francisco: theacademysf.com/

Today, we’re introducing Tenera: behavioral simulations for product teams. Teams are shipping faster than ever, but product decision making hasn’t caught up. For every big bet, product leaders face the same binary choice: ship on instinct, or wait weeks for validation. Tenera predicts how users will react to software before it ships. We train a dedicated model per persona, grounded in customer evidence and behavioral data, so predictions reflect how your specific users behave, not a generic average. It helps teams prioritize, pressure test, and validate high-stakes product decisions - faster and at scale. The winners won’t be the teams that build the most. They’ll be the teams that know what to build first. Book a demo ↓ trytenera.ai
