A studio built for storytellers

CIS Studio is a Buenos Aires-based creative team with over 15 years of experience bringing children's books to life. Since 2010, we've illustrated more than 100 books for authors and publishers around the world.

We specialize in children's illustration because it lets us do something adults rarely get to do — play with imagination freely. And we believe every story deserves that kind of energy.

When you work with us, you're not working with a single freelancer. You're working with a dedicated team that handles illustration, design, formatting, and animation — all under one roof, with one clear point of communication.

HOW IT WORKS

A clear, guided process from idea to finished book

1. You share your story

Tell us about your book, characters, and goals. Whether you’re just starting or already publishing, we’ll understand where you are and what you need.

You receive high-quality, publishing-ready files — including interior pages, covers, and formatting if needed — ready for print and platforms like Amazon KDP.
