Exactly twelve years ago I launched Frontback — a strange, hopeful attempt to make social feel more honest. Now none of my friends post anymore. So I’m building something kind of similar… but totally different. medium.com/@fredd/twelve-yea…

When you're building a social app, you're actually building three products: the core, the graph, and the growth. The Core is what users do and feel inside the app. It’s the easy part — it’s the “I have an idea for an app” that friends call you excited about. The Graph is the network — how they find friends, connect, interact, and stay tied together. A great graph makes the app sticky and essential. The Growth is the engine — how the app spreads naturally, how new users find it, and why they stick. Growth has to be designed, not hoped for.

Amis codeurs européens, if you're in AI, definitely check out @betaworks new AI Camp: Agents. They go deep on emerging tech and are great US backers of EU startups!  betaworks.com/camp

Just added the first outside tester knowing it’s way too early, but waiting for a decent MVP is always a terrible mistake. I hope you like our v0 @mvaloatto

We added 10 more friends and it's really fun. Always terrified to share a work in progress, but we now know our concept is sticky. Next step is to seed to a few ideal users with a proper sharing flow.
