Don't wait for the future. Build it. B150 is the professional network reimagined for GenAI builders — the coders, filmmakers, designers, marketers, and creators using AI to ship real things. This isn't another feed. It's where the people actually building with GenAI show their work, trade what's working, find collaborators, and launch together. WHO IT'S FOR For the builders, the tinkerers, the tastemakers. The ones turning sparks into stories, side hustles into careers, and projects into movements. - Vibe Coding — founders launching new ideas - Vibe Designing — creators building next-gen content - Vibe Marketing — marketers automating workflows - Vibe Filmmaking — filmmakers creating blockbusters - Vibe Gaming — devs building AAA titles - Vibe Creating — experimenting with AI art, music, and writing If you're using GenAI to build something real, this is your network. WHAT YOU CAN DO A COMMUNITY FEED WITHOUT THE NOISE Focused posts, helpful voices, and genuine conversations that move your work forward. No engagement bait. No AI slop. Just builders talking to builders. SHOWCASE YOUR WORK Build a profile that proves you're an AI expert. Show your projects, tools, and skills in a way that makes your work impossible to ignore. DISCOVER THE AI TOOL STACK Explore the Marketplace — a curated guide to the products powering builders across code, design, video, music, and more. Find tools that actually work. List your own and reach the creators who need them. FIND JOBS. FIND TALENT. A focused board of AI job listings and talent across design, engineering, product, and beyond. Whether you're hiring or looking, you'll find people who actually ship. LAUNCH YOUR PROJECT Share your work early. Get beta users and unfiltered feedback from fellow creators who've been there. Build momentum before you launch, not after. JOIN VIBEATHONS AND LIVE EVENTS Build events where creators ship something real in a weekend. Make friends. Make things. Make a dent. ORGANIZE YOUR NETWORK Manage meaningful connections in one place. Filter for strong connections, require personal messages on requests, and keep your network signal-heavy. LEARN FROM OTHER BUILDERS See how others are using GenAI to build products, create films, and automate workflows. Stay in the loop on tool launches, model releases, and AI breakthroughs — so you're always building with fresh ideas. PEER COMMUNITIES (COMING SOON) Small peer groups that keep you accountable, supported, and inspired. A group who's got your back. A NOTE FROM THE FOUNDER I built B150 as a solo founder because something was missing. So many insanely talented builders were putting work into the world, but there was no place built for them to be seen, supported, or celebrated. I vibe coded the entire platform in under 3 months. No team. No funding. Just a Cursor account, $260.40 in credits, and a clear vision: help builders launch publicly, grow faster, and build real momentum. B150 is for the ones who don't just talk — they build. — Adam Perlis, Founder JOIN THE BUILDERS REVOLUTION Download B150 and join the creators reshaping what's possible with GenAI. Start shipping real things with the people building the future alongside you.
I Was There
Read full descriptionHide full description
I Was There is a new take on social networking. It offers users event driven posts where they can share experiences with other users, posting pictures, videos, and text based stories about events in their lives. Threads for specific types of experiences allow you to connect with others who were there. Connect the experience, experience the connection. Blips are events. Blip threads about shared experiences such as concerts, sporting events, festivals, or any other community occasion. Anyone can create a Blip for any type of event, and anyone can upload their media and narratives in the form of Echoes. Cairns are memorials. Cairn threads to connect around the loss of a loved one. Anyone can create a Cairn to honor someone they have lost, or even to remember their pet, and anyone can upload media and narratives to share stories and memories. Monuments are achievements. Monument threads celebrate accomplishments and wins, from buying a first home to graduation to getting a promotion. These Milestones can either be a community announcement or individually proclaimed. Landmarks are destinations. Landmark threads revolve around global locations, either by category or specific point on the map. Want to know where Glowing Lagoons exist? Check the thread. Been to a Black Sand Beach? Share to the thread! Or, join or create a thread for any place. Pebbles are all about you. They are individual experiences not connected to other users except through our natural desire to share. Toss a Pebble and see if it makes a splash! I Was There: housing memories across nations and generations. — Subscription — I Was There is free to download and all users can view, create, and contribute to Blips and Cairns.
