Charting Bridges

of Knowledge

We bridge science and art to make insight matter.

Our story

We are a boutique data design studio.

We teach and design.
Two paths with one core purpose:
to make data human, emotional, and meaningful.

Our story with data began long before Valentina called herself a designer…

Decorative

As a child I dreamt of becoming a superhero. I would pore over atlases, maps, and illustrated books — fascinated by how images could open up the world.

Decorative

That obsession for finding answers and feeding curiosity never left me. Design became the lens through which I learned to connect the dots, distill complexity, and navigate the world.

Decorative

Over time, I also found my own voice. From self-initiated projects like Poppy Field and Oddityviz to publishing books and collaborating with museums, global brands, and NGOs.

Decorative

My practice has developed a perspective I now share worldwide — from Adobe MAX to Design Thinkers, TedX and beyond.

Decorative

Today, Apostrophe One is more than me. It’s a global network of crazy-talented allies, united by the belief that data design can create human connections and bridges of empathy.

The Apostrophe

Design is a language, and even the smallest mark can carry meaning. Here are our values, punctuated.

WHY APOSTROPHE ONE?

The name comes from the small mark in Valentina’s surname. A grammatical detail that always sparks questions and, over time, became a symbol of our work.

An apostrophe signals connection, omission, and ownership. That’s what we do with data: connect dots, surface what’s hidden, and help people own their story.

APOSTROPHE

Knowledge is Power

Design is a catalyst for change. We help people see clearly, understand deeply, and act with confidence.

COLON

Clarity over Simplicity

We don’t dumb things down. We clarify. We visualise data to reflect the richness of the world, without flattening it.

QUESTION MARK

Problem Seeking

We ask before we answer. We examine data from multiple angles to expose bias, uncover hidden stories and challenge assumptions.

EXCLAMATION MARK

Expert Curiosity

Two decades of experience – yet we feel like we’re just getting started. Curiosity, wonder, and care drive every project.

DASH

Breaking the Mould

No templates. No shortcuts. Every design is crafted to let the data speak and connect with its audience

Public speaking

From Adobe MAX to The Royal Institution, Valentina’s keynotes inspire audiences to see data differently – as a lens to widen perspectives and a language that connects people.

Keynotes

From keynote stages to panel discussions, I speak about data storytelling, visual thinking, and the creative process behind complex information design.
