On the practice

“Every Slack message, every Loom, every line of shipped code comes from me — the designer who took the brief. There is no account manager between you and the work, and no junior layer reviewing it after.”

Kazuaki Iso Principal · Osaka

The practice has operated as a solo studio since 2014. A vetted bench of four specialist collaborators — motion, 3D, copy, research — is activated per engagement, but every deliverable is reviewed and shipped under the principal's name.
