1.2M DAUs on Friends

first day at @borndotcom today! time to build some amazing React Native apps 🚀

Super cool to see how positive the feedback on our new Product Preview Life is. It’s exciting to see people extending their social graph with AI friends and building real relationships with them

Happy to share with the public what we’ve been working on. Today, we’re previewing Life: AI friends that feel alive and real. Friends that can send you TikTok’s, know what’s going on in the world, and share content that’s relevant to the era you’re currently in. One of the biggest challenges with AI friends is making conversations stay engaging and genuinely feel real over time. Under the hood, Life combines a recommendation engine with large language models to predict what users want to talk about next. Every conversation generates preference signals that influence future topics, content, and timing, allowing interactions to evolve naturally.

We’re excited to welcome @o_kwasniewski and @SzymonRybczak to Born. They are exceptional engineers and fit perfectly into our mission to rethink how people connect with AI friends through our upcoming product. Together, we’re building the category-defining company in companionship.

We are hiring React Native engineers If you care deeply about craft, product, and building the future of consumer social AI, join us You’ll be working closely with @fabiankamberi and me DMs are open

Start over when good isn't great.

A technically interesting challenge when building Pengu was generating transparent images for each user’s unique Pengu. With over 350 clothing items and countless possible combinations, plus varying device sizes, pre-generating images in the cloud quickly became infeasible. To solve this, we moved the computation to the device itself by leveraging React Native Godot. Here’s how it works: ① The user changes the Pengu’s clothing, and React Native calls a GDScript function. ② Godot opens a subwindow with a specific scene that renders the Pengu. ③ Godot takes a “screenshot” and closes the subwindow. ④ React Native receives the File Path of the screenshot as a return value. You can get quite creative with how you leverage Godot’s subwindows. Screenshots are captured in just a few milliseconds, without the user ever noticing.

One of the most important features for Pengu was the ability to download and launch different games (Godot pck's) on the fly. Under the hood, our React Native Godot library manages the entire Godot lifecycle: stopping, cleaning up, and starting a new instance with a different pck. Everything happens within milliseconds, without restarting the app.

We’re open-sourcing React Native Godot this Sunday. After a year of testing, polishing, and making it scalable across all the different Android devices. Over the next few days, we’ll share all the different features we’ve built and best practices on how to use them. We built much of Pengu’s core functionality on top of this library, and it opened up a whole new world of possibilities for us. I can’t wait to see what you’ll all build with it!

For our new product, we built a chat in React Native that feels like iMessage Here's how we did it: ① Fabric Swift View ② UICollectionView ③ SwiftUI cells via UIHostingConfiguration React is responsible for the state - mutations, fetching, infinite loading - all via React Query. The native Fabric view is purely for rendering. React decides what to show, native decides how to show it The bridge between three frameworks was tricky but worth it. UICollectionView animations come for free and scroll performance is native-smooth No blank spaces and no FPS drops - all powered by the New Architecture Who wants to see the code?

There can never be two social apps that look the same

Consumer social doesn't need form factors that force you to do things. It should multiply what's inside you and give you tools to be human in ways you can't be anywhere else. That's how you reach billions of people. Human relationships are messy, beautifully and brutally so. Greatness starts when you tackle the hard stuff.

Building a consumer (social) app is insanely hard. At Born, we’re obsessed with one thing: quantifiable testing processes. When we started, we had no clue what to even look for--now we do. Here’s the template I wish we had back then 🧵

We’re now @borndotcom and announcing our $15M Series A. Designing joyful experiences has always been my passion. At Born we’re creating AI friends that bring millions of people joy, entertainment, and utility every day. Over the past months, we explored countless ways users could interact with Pengu. I’m incredibly proud of our team for finding a form factor and experience that truly works. Today, Pengu is the largest AI Friend with its own IP, reaching 15M users who send hundreds of thousands of messages every day. I get to build Born with my best friends Fabian and Jannis. With Born, we’re reimagining the future of AI Friends to craft experiences for millions. And yes – we’re hiring.
