Inside the event

What's happening? Bilt.me is teaming up with Time Rich Club and WisprFlow, and Koah the ad network built for AI apps, to host Mobile App Hackathon Night in New York: an evening for getting a real mobile app out of your head and onto your phone, with AI. A friendly hackathon where the only rule is to ship something by the end of the night. Most app ideas never leave the Notes app. Tonight yours does. No code needed. Bring a fresh idea or something you've already started. Describe what you want in plain language, keep refining it, and leave with an app running on your phone that you can show people. All you need is a laptop and the willingness to call something done. You'll be hacking alongside founders, designers, coders and people with too many ideas in their Notes app. Come solo or bring a friend, and we'll help you find teammates. Why come? Build your app with Bilt.me, then hear from Koah on how AI apps start making money from day one. 🍕 Pizza on us Format Teams of one or two. A quick kickoff, then three hours of heads-down hacking with a clear finish line: get it working on your phone. We wrap with demos, so everyone sees what got shipped.
