Our story

Who We Are

Built by a dad who made a board book for his daughter and couldn't stop.

Mara growls. She roars. She stomps around the living room like something prehistoric. So we started calling her "Happy Dinosaur."

On a family trip, I made her a book - crayon drawings on cream paper, ten pages, Mara the Happy Dinosaur goes on an adventure. I printed five copies and surprised my wife with them.

That was four months before Bibbly existed.

Mara loved the book. We read it every morning. She'd grab it off the shelf and shove it in my hands before I'd had coffee. And I couldn't stop thinking: she should have more of these. Not template books with her name pasted in. Books where the characters are her family, in her art style, growing with her.

So I built the engine that makes them.

How we think about recommendations

Quizzes are bad at this. You can't describe your taste in baby names by picking from a dropdown. So we show you two names and you pick one. Then two more. Then two more. Behind the scenes, a logistic regression model with Laplace approximation tracks your preferences across 271 dimensions - phonetics, syllable structure, origin, popularity, semantic meaning. It's the same math behind chess ratings, applied to your taste. We use it for names, clothes, grandparent nicknames, and now the stories we write for your family.
