The hands behind
the fold.

A small studio of precise hands — turning one honest sheet of paper into the email client that holds its shape.

The crease we live by.

CorrielCo began as a single conviction — your correspondence deserves the strength of many layers with the calm of one clean sheet. We fold with intent and we never ship a wrinkle.

Built on Google's trusted APIs, your data stays pressed safely in place while AI sharpens your writing under your full control.

Meet the studio

Three folders, one shared discipline — measure twice, fold once, ship only what lies flat.

Theo Lindqvist

Theo Lindqvist

CEO & Founder

Theo kept Google's infrastructure aligned to the millimeter; every CorrielCo release must lie perfectly flat on his table before it ships.

Amara Osei

Amara Osei

CTO

Amara folds her AI models along careful lines — every one tested crease by crease, released only when it holds its shape.

Yuki Tanaka

Yuki Tanaka

Head of Design

Yuki places every element the way origami masters place a fold — nothing decorative, everything structural.

Pressed into the paper

Privacy, Pressed In

Zero retention folded into the sheet itself, not glued on after. Your emails stay between you and Google's trusted systems.

Always Folding Forward

A public changelog and new folds throughout the year — the paper never sits still.

Members First

We fold what members actually ask for, not what looks cleverest on the shelf. You use it; you shape it.
