Everything on Lounge works in your pocket
The feed, in-person meetups by city, the news desk, the tools directory and the podcast player, built for the phone, not shrunk to fit it. Add it to your home screen and it opens like an app.
One link for everything you have built
Add the products you have launched, the company you run, the demos worth a look and the AI stack you use. Have a GitHub or Hugging Face? Connect them and repos, models and demos import themselves. The page keeps itself current, achievements, masterminds attended, the lot. It is the link builders send instead of a résumé or a deck.
- ✓Products, projects and demos with upvotes
- ✓Company, role and ARR band for founders
- ✓GitHub and Hugging Face synced hourly, if you use them
- ✓Public by default, members-only if you prefer
