The studio
✦ Est. 2025Formely Ceylon Agency
Formerly Ceylon Agency
Now building full-stack brands.
Concept Knock grew out of Ceylon Agency, where we spent years running strategy, design and marketing. We rebuilt the studio to go deeper full-service branding plus the digital and tech chops (websites, product) that used to be a separate lane.
While Ceylon Agency still exists, our entire focus and creative energy is now poured into Concept Knock. It's a new form, a rebrand, and an evolution of how we build for ambitious founders.
