It Started in a Trampoline Hall
Two years ago, I was at a trampoline hall with my 5-year-old daughter. In a moment of trying to explain something to her, we accidentally jumped on the same pad. She broke her leg.
Home-bound with a plastered leg that needed to stay elevated, she received a gift from a teacher friend: a collection of TipToi interactive books. As I watched her explore these books with the magical pen that made them speak and sing, a thought struck me: "What if I could create my own content? I could make stories about fairies, the history of dragons, anything she loves..."
"I figured those books would never entertain her for 2 weeks straight, so I thought, wouldn't it be great if it was possible to create my own material?"
Down the Rabbit Hole
That simple wish sent me on an unexpected journey. I made a video explaining the TipToi concept to two friends, raving about the potential if there was a way to make books for the platform. Soon, I was diving deep into electrical engineering, infrared sensors, optics, dot patterns, and patent research – territories completely new to me.
What fascinated me most was how the infrared sensor filters out the colored picture to reveal hidden dot patterns, and how the pen retains state to enable scenarios and puzzles. But after seeing the reverse-engineered formats TipToi used, I felt empathy for the Ravensburger team – creating a TipToi book was terribly complicated.
From Hacking to Building
I spent months trying to build my own optical sensor, wrestling with frequency filters, IR bands, and lens distances. It wasn't easy at all. I managed to get something that could see dot patterns, but the closed SDK and obtuse binary formats of TipToi made me realize: hacking the existing system would never reach its full potential. I needed to build something new.
More Than Interactive Books
What started as a wish to create custom books for my daughter has evolved into something much bigger. As a board game maker (Money Maker Games), I know how even with graphics and manuals, games can be difficult to comprehend. As a musician working with sheet music in studios, I've experienced the struggle of trying to re-hear crucial parts.
But the real game-changer is education. Everyone talks about "individualized learning," but it's mostly a hoax – you'd need three teachers in every classroom to truly achieve it. Imagine if teachers could create different books with exercises for each individual student, tracking their progress through a dashboard. That's the world Papiro is building.
"What I considered a 'simple' project is not straightforward at all..."
Today, we're finalizing our prototype platform with a "pen emulator" – and fittingly, our demo book tells the story of two entrepreneurs building a business. It's meta, but it perfectly demonstrates how authors can use consistent characters and interactive elements to bring any story to life.
Join Our Journey
From that trampoline hall accident to reimagining how billions interact with printed materials – board games, sheet music, educational content, restaurant menus, tourist guides – Papiro is on a mission to make paper truly interactive and accessible to everyone.
We're currently preparing to open our first funding round. If you believe in a world where any printed material can become interactive, where teachers can truly personalize learning, and where creativity has no bounds – we'd love to hear from you.
