Biggest update I’ve ever shared… Bloom (YC X25) raised $3.4M to unlock the creator economy for software. Let’s be honest: web apps are easy, but building and sharing mobile apps sucks - XCode builds, Apple Developer reviews, TestFlight invites… all make going from idea to an app on users’ hands a slow and painful process. With Bloom you can make a full-stack mobile app by talking into your phone and then share it instantly with a single link. --- Bloom started last Christmas. After landing in Barcelona to visit family, I immediately asked my mom where I could buy a monitor. She was confused, but I was on a mission: I needed those two weeks to run experiments on an idea that had been floating around in my head for months – could I build a mobile app that builds mobile apps? This wasn't just any idea. It was the kind that kept me up at night. I wanted to see if this pipe dream was technically feasible – could we dynamically change a mobile app's functionality on the fly? I came back to Zurich with something promising, but nothing definite. In mid-January, I had a critical conversation with my co-founder Sirian Maathuis. We were making steady progress with our previous product, Fireview, but I couldn't shake this feeling about Bloom. "This could be extremely big," I told him. "It could change the world. It's probably the coolest product we could ever build." With the YC application deadline just three weeks away, we pivoted and scrambled to build an MVP. After submitting our application at midnight, Sirian stayed up until 4 AM recording our demo. Once David Lieb saw our application, things moved fast and we got to spend three intense months in San Francisco with YC. We closed our round 5 days before demo day and didn't have a deck - our product demo did all the talking. --- This $3.4M round is led by Moonfire Ventures , with participation from Y Combinator and Pioneer We're also backed by an incredible group of founders and operators Thomas Wolf (Founder/CSO, HuggingFace) Bob van Luijt (Founder/CEO, Weaviate) Jamie Turner (Founder/CEO, Convex) Theo - t3.gg (Founder/CEO, T3Chat) Evan Bacon 🥓 (Expo) cedric (Expo) colinevans (OpenAI) Ron Besseling (Whatsapp) Clive Anyonye (Meta) Robert van Gaal (Google, Vesper) Nick Lenten (Founder/CEO, Ahead Health) Helena (Founder Embassy) Chris Smoak (serial founder & YC alum) Gianmaria Sbetta (Google) Ruben (Founder, VC Corner) Special thanks to those who believed in us from the beginning: Founderful Campus, Andrew Daniels 💜, Chase Myers , S2S, Jamie Turner , and David Lieb We're now back in Europe, building out the founding team that is going to redefine how the next wave of apps is built. If you’re someone that loves building product, solving complex problems and working on the future of software, we’d love to talk. There's so much to build, and we're just getting started.
