I'm a technical cofounder who has already been through the full cycle of building and launching a startup. I know what it takes to go from idea to product , and I've done it before.

My previous startup was B2B, where I learned how to sell, how to listen to the market, and how to turn feedback into product decisions. That experience shaped how I think about users, retention, and growth.

What I'm bringing to the table is rare: the technical depth to ship fast, the entrepreneurial experience to avoid early mistakes, and a product that is already built and already growing in one of the largest markets in the world.

Librivia is a social reading platform live and growing in Brazil. We built what the reading world has been missing: a place where your entire literary journey lives — discovering books, tracking your progress, joining reading clubs, connecting with friends, and sharing your story as a reader.
What makes it different is intelligence. The platform learns who you are as a reader over time, using AI and machine learning to deliver recommendations, insights, and experiences that feel personal — not generic. We have a pipeline of ML-driven features that turn reading into something social, viral, and deeply engaging.
Brazil was just the beginning. The global market for passionate readers is massive and underserved, and we're ready to expand — Europe, North America, and beyond.
I'm looking for a cofounder with experience in B2C growth, international expansion, or community building. Someone who sees the same opportunity I do: reading is one of the most universal human habits, and no one has built the platform it deserves.
Let's build it together.
